As their energy reaches down to only a few meV, they are present at all temperatures and substantially influence the properties of magnetic systems. To study the spin excitations in solids from first principles, we have developed a computational scheme based on many-body perturbation theory within the full-potential linearized augmented plane-wave (FLAPW) method. The main quantity of interest is the dynamical transverse spin susceptibility or magnetic response function, from which magnetic excitations, including single-particle spin-flip Stoner excitations and collective spin-wave modes as well as their lifetimes, can be obtained. In order to describe spin waves we include appropriate vertex corrections in the form of a multiple-scattering T matrix, which describes the coupling of electrons and holes with different spins. The electron–hole interaction incorporates the screening of the many-body system within the random-phase approximation. To reduce the numerical cost in evaluating the four-point T matrix, we exploit a transformation to maximally localized Wannier functions that takes advantage of the short spatial range of electronic correlation in the partially filled d or f orbitals of magnetic materials. The theory and the implementation are discussed in detail. In particular, we show how the magnetic response function can be evaluated for arbitrary k points. This enables the calculation of smooth dispersion curves, allowing one to study fine details in the k dependence of the spin-wave spectra. We also demonstrate how spatial and time-reversal symmetry can be exploited to accelerate substantially the computation of the four-point quantities. As an illustration, we present spin-wave spectra and dispersions for the elementary ferromagnet bcc Fe, B2-type tetragonal FeCo, and CrO2 calculated with our scheme. The results are in good agreement with available experimental data.","lang":"eng"}],"external_id":{"isi":["000356811000008"],"pmid":["24577607"]},"language":[{"iso":"eng"}],"ddc":["530"],"quality_controlled":"1","year":"2014","date_created":"2020-08-27T21:00:45Z","publisher":"Springer","title":"Spin excitations in solids from many-body perturbation theory","type":"book_chapter","status":"public","editor":[{"first_name":"Cristiana","last_name":"Di Valentin","full_name":"Di Valentin, Cristiana"},{"first_name":"Silvana","full_name":"Botti, Silvana","last_name":"Botti"},{"first_name":"Matteo","full_name":"Cococcioni, Matteo","last_name":"Cococcioni"}],"department":[{"_id":"296"},{"_id":"35"},{"_id":"15"},{"_id":"230"}],"user_id":"16199","series_title":" Topics in Current Chemistry","_id":"18471","file_date_updated":"2020-08-30T14:48:45Z","isi":"1","pmid":"1","has_accepted_license":"1","publication_identifier":{"eisbn":["978-3-642-55068-3"],"eissn":["1436-5049"],"issn":["0340-1022"],"isbn":["978-3-642-55067-6"]},"publication_status":"published","intvolume":" 347","page":"259-301","citation":{"apa":"Friedrich, C., Şaşıoğlu, E., Müller, M., Schindlmayr, A., & Blügel, S.

Although computationally more demanding than density functional theory, it has the distinct advantage that the exact expressions for all relevant observables, including the ground-state total energy, in terms of the Green function are known explicitly. The most important application, however, lies in the calculation of excited states, whose energies correspond directly to the poles of the Green function in the complex frequency plane. The accuracy of results obtained within this framework is only limited by the choice of the exchange-correlation self-energy, which must still be approximated in actual implementations. In this respect, the GW approximation has proved highly successful for systems governed by the Coulomb interaction. It yields band structures of solids, including the band gaps of semiconductors, as well as atomic and molecular ionization energies in very good quantitative agreement with experimental photoemission data.","lang":"eng"}],"publication":"Many-Electron Approaches in Physics, Chemistry and Mathematics"},{"type":"journal_article","status":"public","user_id":"16199","department":[{"_id":"296"},{"_id":"35"},{"_id":"15"},{"_id":"170"},{"_id":"230"}],"_id":"18473","file_date_updated":"2020-08-30T14:52:27Z","article_type":"original","isi":"1","article_number":"05FY02","publication_status":"published","has_accepted_license":"1","publication_identifier":{"issn":["0021-4922"],"eissn":["1347-4065"]},"citation":{"short":"S.

As in our recent study of rubrene using the same methodology [S. Yanagisawa, Y. Morikawa, and A. Schindlmayr, Phys. Rev. B 88, 115438 (2013)], this increase in the bandwidth is due to the strong variation of the GW self-energy correction across the Brillouin zone, which in turn reflects the increasing hybridization of the HOMOu states of neighboring picene molecules from Γ to Y. In contrast, the width of the lower HOMO (HOMOl) band along Γ–Y remains almost unchanged, consistent with the fact that the HOMOl(Γ) and HOMOl(Y) states exhibit the same degree of hybridization, so that the nodal structure of the wave functions and the matrix elements of the self-energy correction are very similar."}],"external_id":{"isi":["000338316200158"]},"language":[{"iso":"eng"}],"ddc":["530"],"issue":"5S1","quality_controlled":"1","year":"2014","date_created":"2020-08-27T21:21:24Z","publisher":"IOP Publishing and The Japan Society of Applied Physics","title":"Theoretical investigation of the band structure of picene single crystals within the GW approximation"},{"file_date_updated":"2022-01-06T06:53:34Z","department":[{"_id":"296"},{"_id":"35"},{"_id":"15"},{"_id":"170"},{"_id":"230"}],"user_id":"16199","series_title":"Key Technologies","_id":"18474","status":"public","editor":[{"full_name":"Blügel, Stefan","last_name":"Blügel","first_name":"Stefan"},{"first_name":"Nicole","last_name":"Helbig","full_name":"Helbig, Nicole"},{"first_name":"Volker","full_name":"Meden, Volker","last_name":"Meden"},{"first_name":"Daniel","last_name":"Wortmann","full_name":"Wortmann, Daniel"}],"type":"book_chapter","conference":{"location":"Jülich","end_date":"2014-03-21","start_date":"2014-03-10","name":"45th Spring School of the Institute of Solid State Research"},"main_file_link":[{"url":"http://hdl.handle.net/2128/8540","open_access":"1"}],"volume":74,"author":[{"full_name":"Friedrich, Christoph","last_name":"Friedrich","first_name":"Christoph"},{"last_name":"Schindlmayr","orcid":"0000-0002-4855-071X","full_name":"Schindlmayr, Arno","id":"458","first_name":"Arno"}],"oa":"1","date_updated":"2025-12-16T08:07:31Z","intvolume":" 74","page":"A4.1-A4.21","citation":{"chicago":"Friedrich, Christoph, and Arno Schindlmayr. “Many-Body Perturbation Theory: The GW Approximation.” In Computing Solids: Models, Ab Initio Methods and Supercomputing, edited by Stefan Blügel, Nicole Helbig, Volker Meden, and Daniel Wortmann, 74:A4.1-A4.21.

We exploit controlled (multi-)terahertz waveforms with peak fields of 72 MV cm−1 to drive coherent interband polarization combined with dynamical Bloch oscillations in semiconducting gallium selenide. These dynamics entail the emission of phase-stable high-harmonic transients, covering the entire terahertz-to-visible spectral domain between 0.1 and 675 THz.

Furthermore, the investigated zone center A1 -TO phonon modes are characterized by a pronounced stoichiometry dependence.

The formation of the NC structure plays an important role in the process of fission of higher-order (N) solitons in optical fibers. After the splitting of the initial N soliton into a nonuniform chain of fundamental quasisolitons, the tallest one travels along the entire chain, through consecutive collisions with other solitons, and then escapes, while the remaining chain of pulses stays as a bound state, due to the radiation-mediated interaction between them. Increasing the initial soliton's order, N, leads to the transmission through, and release of additional solitons with enhanced power, along with the emission of radiation, which may demonstrate a broadband supercontinuum spectrum. The NC dynamical regime remains robust in the presence of extra perturbations, such as the Raman and self-steepening effects, and dispersion terms above the third order. It is demonstrated that essentially the same NC mechanism is induced by the TOD in finite segments of periodic wave trains (in particular, soliton chains). A difference from the mechanical NC is that the TOD-driven pulse passing through the soliton array collects energy and momentum from other solitons. Thus, uniform and nonuniform arrays of nonlinear wave pulses offer an essential extension of the mechanical NC, in which the quasiparticles, unlike mechanical beads, interact inelastically, exchanging energy and generating radiation. Nevertheless, the characteristic phenomenology of NC chains may be clearly identified in these nonlinear-wave settings too.","lang":"eng"}],"type":"journal_article","publication":"Physical Review A ","language":[{"iso":"eng"}],"article_number":"063808","user_id":"49063","department":[{"_id":"293"}],"_id":"43254","citation":{"chicago":"Driben, R., B.A. Malomed, A.

In the presence of the trapping harmonic-oscillator (HO) potential, we report the existence of even, odd, and asymmetric spatial modes. They feature alternating domains with opposite directions of the pseudospin, i.e., antiferromagnetic structures, which is explained by the interplay of the linear couplings, HO confinement, and repulsive self-interaction. The number of the domains is determined by the strength of the SO coupling. The modes are constructed analytically in the weakly nonlinear system. The dynamical stability of the modes is investigated by means of the Bogoliubov–de Gennes equations and direct simulations. A notable result is that the multi-domain-wall (DW) structures are stable, alternating between odd and even shapes, while the simplest single-DW structure is unstable. Thus, the system features a transition to the complex ground states under the action of the SO coupling. The addition of the Zeeman splitting transforms the odd modes into asymmetric ones via spontaneous symmetry breaking. The results suggest possibilities for switching the binary system between states with opposite (pseudo)magnetization by external fields, and realization of similar stable states and dynamical effects in solid-state and nonlinear-optical settings emulated by the SO-coupled BECs."}],"status":"public","publication":"Physical Review A ","type":"journal_article","article_number":"013607","language":[{"iso":"eng"}],"_id":"43258","department":[{"_id":"293"}],"user_id":"49063"},{"abstract":[{"text":"We demonstrate that trapping of dispersive waves between two optical solitons takes place when resonant scattering of the waves on the solitons leads to nearly perfect reflections.

One can expect that such interactions have an influence on the second harmonic generation. We apply the Discontinuous Galerkin Time Domain method and the hydrodynamic Maxwell-Vlasov model to simulate the linear and nonlinear optical response from SRR arrays. The simulations show that dense placement of the constituent building blocks appears not always optimal and collective effects can lead to a significant suppression of the near fields at the fundamental frequency and, consequently, to the decrease of the SHG intensity. We demonstrate also the great role of the symmetry degree of the array layout which results in the variation of the SHG efficiency in range of two orders of magnitude."}],"publication":"Ultrafast Phenomena and Nanophotonics XVII","title":"Optimal second-harmonic generation in split-ring resonator arrays","date_created":"2018-08-21T07:38:08Z","publisher":"SPIE","year":"2013","file_date_updated":"2018-08-21T07:41:47Z","department":[{"_id":"15"},{"_id":"293"},{"_id":"170"},{"_id":"61"},{"_id":"230"}],"series_title":"SPIE Proceedings","user_id":"49063","_id":"3961","status":"public","editor":[{"first_name":"Markus","last_name":"Betz","full_name":"Betz, Markus"},{"full_name":"Elezzabi, Abdulhakem Y.","last_name":"Elezzabi","first_name":"Abdulhakem Y."},{"full_name":"Song, Jin-Joo","last_name":"Song","first_name":"Jin-Joo"},{"last_name":"Tsen","full_name":"Tsen, Kong-Thon","first_name":"Kong-Thon"}],"type":"conference","doi":"10.1117/12.2003279","volume":8623,"author":[{"first_name":"Yevgen","last_name":"Grynko","id":"26059","full_name":"Grynko, Yevgen"},{"full_name":"Meier, Torsten","id":"344","last_name":"Meier","orcid":"0000-0001-8864-2072","first_name":"Torsten"},{"first_name":"Stefan","last_name":"Linden","full_name":"Linden, Stefan"},{"last_name":"Niesler","full_name":"Niesler, Fabian B.
