text: "Given a real semisimple connected Lie group $G$ and a discrete torsion-free\r\nsubgroup
$\\Gamma < G$ we prove a precise connection between growth rates of the\r\ngroup
$\\Gamma$, polyhedral bounds on the joint spectrum of the ring of\r\ninvariant
differential operators, and the decay of matrix coefficients. In\r\nparticular,
this allows us to completely characterize temperedness of\r\n$L^2(\\Gamma\\backslash
G)$ in this general setting."

text: "We prove Feynman-Kac formulas for the semigroups generated by selfadjoint\r\noperators
in a class containing Fr\\\"ohlich Hamiltonians known from solid state\r\nphysics.
The latter model multi-polarons, i.e., a fixed number of quantum\r\nmechanical
electrons moving in a polarizable crystal and interacting with the\r\nquantized
phonon field generated by the crystal's vibrational modes. Both the\r\nelectrons
and phonons can be confined to suitable open subsets of Euclidean\r\nspace. We
also include possibly very singular magnetic vector potentials and\r\nelectrostatic
potentials. Our Feynman-Kac formulas comprise Fock space\r\noperator-valued multiplicative
functionals and can be applied to every vector\r\nin the underlying Hilbert space.
In comparison to the renormalized Nelson\r\nmodel, for which analogous Feynman-Kac
formulas are known, the analysis of the\r\ncreation and annihilation terms in
the multiplicative functionals requires\r\nnovel ideas to overcome difficulties
caused by the phonon dispersion relation\r\nbeing constant. Getting these terms
under control and generalizing other\r\nconstruction steps so as to cover confined
systems are the main achievements of\r\nthis article."

text: "In this proceeding we consider a translation invariant Nelson type model
in\r\ntwo spatial dimensions modeling a scalar relativistic particle in interaction\r\nwith
a massive radiation field. As is well-known, the corresponding Hamiltonian\r\ncan
be defined with the help of an energy renormalization. First, we review a\r\nFeynman-Kac
formula for the semigroup generated by this Hamiltonian proven by\r\nthe authors
in a recent preprint (where several matter particles and exterior\r\npotentials
are treated as well). After that, we employ a few technical key\r\nrelations and
estimates obtained in our preprint to present an otherwise\r\nself-contained derivation
of new Feynman-Kac formulas for the fiber\r\nHamiltonians attached to fixed total
momenta of the translation invariant\r\nsystem. We conclude by inferring an alternative
derivation of the Feynman-Kac\r\nformula for the full translation invariant Hamiltonian."

text: "Given a geometrically finite hyperbolic surface of infinite volume it is
a\r\nclassical result of Patterson that the positive Laplace-Beltrami operator
has\r\nno $L^2$-eigenvalues $\\geq 1/4$. In this article we prove a generalization
of\r\nthis result for the joint $L^2$-eigenvalues of the algebra of commuting\r\ndifferential
operators on Riemannian locally symmetric spaces $\\Gamma\\backslash\r\nG/K$ of
higher rank. We derive dynamical assumptions on the $\\Gamma$-action on\r\nthe
geodesic and the Satake compactifications which imply the absence of the\r\ncorresponding
principal eigenvalues. A large class of examples fulfilling these\r\nassumptions
are the non-compact quotients by Anosov subgroups."

text: In this article we prove meromorphic continuation of weighted zeta functions
in the framework of open hyperbolic systems by using the meromorphically continued
restricted resolvent of Dyatlov and Guillarmou (2016). We obtain a residue formula
proving equality between residues of weighted zetas and invariant Ruelle distributions.
We combine this equality with results of Guillarmou, Hilgert and Weich (2021)
in order to relate the residues to Patterson-Sullivan distributions. Finally we
provide proof-of-principle results concerning the numerical calculation of invariant
Ruelle distributions for 3-disc scattering systems.

text: "We present a numerical algorithm for the computation of invariant Ruelle\r\ndistributions
on convex co-compact hyperbolic surfaces. This is achieved by\r\nexploiting the
connection between invariant Ruelle distributions and residues\r\nof meromorphically
continued weighted zeta functions established by the authors\r\ntogether with
Barkhofen (2021). To make this applicable for numerics we express\r\nthe weighted
zeta as the logarithmic derivative of a suitable parameter\r\ndependent Fredholm
determinant similar to Borthwick (2014). As an additional\r\ndifficulty our transfer
operator has to include a contracting direction which\r\nwe account for with techniques
developed by Rugh (1992). We achieve a further\r\nimprovement in convergence speed
for our algorithm in the case of surfaces with\r\nadditional symmetries by proving
and applying a symmetry reduction of weighted\r\nzeta functions."

We provide a Lieb-Robinson bound under substantially relaxed\r\nassumptions on
the potentials. We also improve the associated one-body\r\nLieb-Robinson bound
on $L^2$-overlaps to an almost ballistic one (i.e., an\r\nalmost linear light
cone) under the same relaxed assumptions. Applications\r\ninclude the existence
of the infinite-volume dynamics and clustering of ground\r\nstates in the presence
of a spectral gap. We also develop a fermionic continuum\r\nnotion of conditional
expectation and use it to approximate time-evolved\r\nfermionic observables by
local ones, which opens the door to other applications\r\nof the Lieb-Robinson
bounds."

text: "In the Bogoliubov-Fr\\\"ohlich model, we prove that an impurity immersed
in a\r\nBose-Einstein condensate forms a stable quasi-particle when the total
momentum\r\nis less than its mass times the speed of sound. The system thus exhibits\r\nsuperfluid
behavior, as this quasi-particle does not experience friction. We do\r\nnot assume
any infrared or ultraviolet regularization of the model, which\r\ncontains massless
excitations and point-like interactions."

text: "For a compact Riemannian locally symmetric space $\\Gamma\\backslash G/K$
of\r\narbitrary rank we determine the location of certain Ruelle-Taylor resonances\r\nfor
the Weyl chamber action. We provide a Weyl-lower bound on an appropriate\r\ncounting
function for the Ruelle-Taylor resonances and establish a spectral gap\r\nwhich
is uniform in $\\Gamma$ if $G/K$ is irreducible of higher rank. This is\r\nachieved
by proving a quantum-classical correspondence, i.e. a\r\n1:1-correspondence between
horocyclically invariant Ruelle-Taylor resonant\r\nstates and joint eigenfunctions
of the algebra of invariant differential\r\noperators on $G/K$."
