We theoretically and experimentally reveal that when the structural symmetry of the meta-atom is incompatible with the lattice symmetry of an array, some generalized nonlinear geometric phases appear, which offers new possibilities for harmonic generation control beyond the accessible symmetries governed by the selection rule. The underlying mechanism is attributed to the modified rotation of the effective principal axis of a dense meta-atom array, where the strong coupling among the units gives rise to a generalized linear geometric phase modulation of the pump light. Therefore, nonlinear geometric phases carried by third-harmonic emissions are the natural result of the wave-mixing process among the modes excited at the fundamental frequency. This mechanism further points out a new strategy to predict the nonlinear geometric phases delivered by the nanostructures according to their linear responses. Our design is simple and efficient and offers alternatives for the nonlinear meta-devices that are capable of flexible photon generation and manipulation.","lang":"eng"}],"language":[{"iso":"eng"}],"main_file_link":[{"url":"https://pubs.acs.org/doi/full/10.1021/acsphotonics.3c01163","open_access":"1"}],"doi":"10.1021/acsphotonics.3c01163","publication_identifier":{"issn":["2330-4022","2330-4022"]},"author":[{"last_name":"Liu","first_name":"Bingyi","full_name":"Liu, Bingyi"},{"full_name":"Geromel, René","last_name":"Geromel","first_name":"René"},{"full_name":"Su, Zhaoxian","first_name":"Zhaoxian","last_name":"Su"},{"full_name":"Guo, Kai","last_name":"Guo","first_name":"Kai"},{"last_name":"Wang","first_name":"Yongtian","full_name":"Wang, Yongtian"},{"full_name":"Guo, Zhongyi","first_name":"Zhongyi","last_name":"Guo"},{"first_name":"Lingling","last_name":"Huang","full_name":"Huang, Lingling"},{"id":"30525","full_name":"Zentgraf, Thomas","first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101"}],"year":"2023","title":"Nonlinear Dielectric Geometric-Phase Metasurface with Simultaneous Structure and Lattice Symmetry Design","article_type":"original","intvolume":"        10","publication_status":"published","date_updated":"2024-04-16T06:47:40Z","oa":"1","citation":{"ama":"Liu B, Geromel R, Su Z, et al.

We initiate the study of a quantum analogue of NPSPACE, denoted\r\nStreaming-QCMASPACE (SQCMASPACE), where an exponentially long classical proof\r\nis streamed to a poly-space quantum verifier. Besides two main results, we also\r\nshow that a quantum analogue of Savitch's theorem is unlikely to hold, as\r\nSQCMASPACE=NEXP. For completeness, we introduce Streaming-QMASPACE (SQMASPACE)\r\nwith an exponentially long streamed quantum proof, and show SQMASPACE=QMA_EXP\r\n(quantum analogue of NEXP). Our first main result shows, in contrast to the\r\nclassical setting, the solution space of a quantum constraint satisfaction\r\nproblem (i.e. a local Hamiltonian) is always connected when exponentially long\r\nproofs are permitted. For this, we show how to simulate any Lipschitz\r\ncontinuous path on the unit hypersphere via a sequence of local unitary gates,\r\nat the expense of blowing up the circuit size. This shows quantum\r\nerror-correcting codes can be unable to detect one codeword erroneously\r\nevolving to another if the evolution happens sufficiently slowly, and answers\r\nan open question of [Gharibian, Sikora, ICALP 2015] regarding the Ground State\r\nConnectivity problem. Our second main result is that any SQCMASPACE computation\r\ncan be embedded into \"unentanglement\", i.e. into a quantum constraint\r\nsatisfaction problem with unentangled provers. Formally, we show how to embed\r\nSQCMASPACE into the Sparse Separable Hamiltonian problem of [Chailloux,\r\nSattath, CCC 2012] (QMA(2)-complete for 1/poly promise gap), at the expense of\r\nscaling the promise gap with the streamed proof size. As a corollary, we obtain\r\nthe first systematic construction for obtaining QMA(2)-type upper bounds on\r\narbitrary multi-prover interactive proof systems, where the QMA(2) promise gap\r\nscales exponentially with the number of bits of communication in the\r\ninteractive proof."}]},{"doi":"10.1063/5.0142389","article_number":"141702","language":[{"iso":"eng"}],"date_updated":"2023-04-06T06:02:58Z","publication_status":"published","intvolume":"       122","article_type":"original","title":"Three-dimensional dipole momentum analog based on L-shape metasurface","year":"2023","author":[{"full_name":"Li, Tianyou","first_name":"Tianyou","last_name":"Li"},{"full_name":"Chen, Yanjie","last_name":"Chen","first_name":"Yanjie"},{"full_name":"Wang, Yongtian","last_name":"Wang","first_name":"Yongtian"},{"id":"30525","full_name":"Zentgraf, Thomas","last_name":"Zentgraf","first_name":"Thomas","orcid":"0000-0002-8662-1101"},{"full_name":"Huang, Lingling","first_name":"Lingling","last_name":"Huang"}],"publication_identifier":{"issn":["0003-6951","1077-3118"]},"type":"journal_article","keyword":["Physics and Astronomy (miscellaneous)"],"department":[{"_id":"15"},{"_id":"230"},{"_id":"289"},{"_id":"623"}],"date_created":"2023-04-06T06:01:06Z","abstract":[{"text":"The achievement of a flat metasurface has realized extraordinary control over light–matter interaction at the nanoscale, enabling widespread use in imaging, holography, and biophotonics. However, three-dimensional metasurfaces with the potential to provide additional light–matter manipulation flexibility attract only little interest. Here, we demonstrate a three-dimensional metasurface scheme capable of providing dual phase control through out-of-plane plasmonic resonance of L-shape antennas. Under circularly polarized excitation at a specific wavelength, the L-shape antennas with rotating orientation angle act as spatially variant three-dimensional tilted dipoles and are able to generate desire phase delay for different polarization components. Generalized Snell's law is achieved for both in-plane and out-of-plane dipole components through arranging such L-shape antennas into arrays. These three-dimensional metasurfaces suggest a route for wavefront modulation and a variety of nanophotonic applications.","lang":"eng"}],"issue":"14","publication":"Applied Physics Letters","user_id":"30525","volume":122,"publisher":"AIP Publishing","_id":"43421","status":"public","quality_controlled":"1","citation":{"ieee":"T.

Typically, bulky pulse compressors consisting of gratings or prisms are used\r\nto address this issue by precompensating the dispersion of the optical components. However, these devices are only able to compensate for a part of the dispersion (second-order dispersion). Here, we present a compact pulse-shaping device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral phase delay allowing for a full dispersion control. Furthermore, with specific phase encodings, this device can be used to temporally reshape the incident laser pulses into more complex pulse forms such as a double pulse. We verify the performance of our device by using an SHG-FROG measurement setup together with a retrieval algorithm to extract the dispersion that our device applies to an incident laser pulse."}],"main_file_link":[{"url":"https://pubs.acs.org/doi/full/10.1021/acs.nanolett.2c04980","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1021/acs.nanolett.2c04980","title":"Compact Metasurface-Based Optical Pulse-Shaping Device","year":"2023","author":[{"last_name":"Geromel","first_name":"René","full_name":"Geromel, René"},{"last_name":"Georgi","first_name":"Philip","full_name":"Georgi, Philip"},{"full_name":"Protte, Maximilian","first_name":"Maximilian","last_name":"Protte","id":"46170"},{"full_name":"Lei, Shiwei","last_name":"Lei","first_name":"Shiwei"},{"id":"49683","full_name":"Bartley, Tim","last_name":"Bartley","first_name":"Tim"},{"last_name":"Huang","first_name":"Lingling","full_name":"Huang, Lingling"},{"first_name":"Thomas","last_name":"Zentgraf","orcid":"0000-0002-8662-1101","full_name":"Zentgraf, Thomas","id":"30525"}],"publication_identifier":{"issn":["1530-6984","1530-6992"]},"publication_status":"published","date_updated":"2023-05-12T11:17:51Z","article_type":"original","intvolume":"        23"},{"doi":"10.1109/lpt.2023.3277515","language":[{"iso":"eng"}],"intvolume":"        35","publication_status":"published","date_updated":"2023-06-06T10:13:05Z","publication_identifier":{"issn":["1041-1135","1941-0174"]},"author":[{"id":"38254","last_name":"Kruse","first_name":"Stephan","full_name":"Kruse, Stephan"},{"last_name":"Serino","first_name":"Laura","full_name":"Serino, Laura","id":"88242"},{"id":"88605","full_name":"Folge, Patrick Fabian","last_name":"Folge","first_name":"Patrick Fabian"},{"last_name":"Echeverria Oviedo","first_name":"Dana","full_name":"Echeverria Oviedo, Dana"},{"first_name":"Abhinandan","last_name":"Bhattacharjee","full_name":"Bhattacharjee, Abhinandan"},{"first_name":"Michael","last_name":"Stefszky","full_name":"Stefszky, Michael","id":"42777"},{"id":"37144","full_name":"Scheytt, J.

Wave-mixing experiments are often described with semiclassical models, where the light is modeled classically and the material quantum mechanically. Here, however, we use a fully quantized model, where the light is given by a quantum state of light. Quantum light involves more degrees of freedom than classical light as e.g., its photon statistics and quantum correlations, which is a promising resource for quantum devices, such as quantum memories. The light-matter interaction is treated with a Jaynes-Cummings type model and the quantum field is given by a single mode since the quantum dots are embedded in a microcavity. We present numerical simulations of the four-wave-mixing response of a homogeneous system for pulse sequences and find a significant dependence of the result on the photon statistics of the incident pulses. The model constitutes a problem with a large state space which arises from the frequency distribution of the transition energies of the inhomogeneously broadened quantum dot ensemble that is coupled with a quantum light mode. Here we approximate the dynamics by summing over individual quantum dot-microcavity systems. Photon echoes arising from the excitation with different quantum states of light are simulated and compared."}],"series_title":"SPIE Proceedings","language":[{"iso":"eng"}],"article_number":"124190H","doi":"10.1117/12.2647700","author":[{"id":"55958","full_name":"Rose, Hendrik","last_name":"Rose","orcid":"0000-0002-3079-5428","first_name":"Hendrik"},{"full_name":"Grisard, S.","last_name":"Grisard","first_name":"S."},{"last_name":"Trifonov","first_name":"A.

PVVBs are typically generated through the superposition of perfect vortex beams, which suffer from the limited number of topological charges (TCs). Furthermore, dynamic control of PVVBs is desirable and has not been reported. We propose and experimentally demonstrate hybrid grafted perfect vector vortex beams (GPVVBs) and their dynamic control. Hybrid GPVVBs are generated through the superposition of grafted perfect vortex beams with a multifunctional metasurface. The generated hybrid GPVVBs possess spatially variant rates of polarization change due to the involvement of more TCs. Each hybrid GPVVB includes different GPVVBs in the same beam, adding more design flexibility. Moreover, these beams are dynamically controlled with a rotating half waveplate. The generated dynamic GPVVBs may find applications in the fields where dynamic control is in high demand, including optical encryption, dense data communication, and multiple particle manipulation.","lang":"eng"}]},{"keyword":["Atomic and Molecular Physics","and Optics"],"type":"journal_article","department":[{"_id":"15"},{"_id":"230"},{"_id":"623"},{"_id":"288"}],"date_created":"2023-07-03T14:08:36Z","abstract":[{"text":"Interference between single photons is key for many quantum optics experiments and applications in quantum technologies, such as quantum communication or computation.
