A Statistical Benchmark for BosonSampling
Mattia Walschaers, Jack Kuipers, Juan-Diego Urbina +4
Computing the state of a quantum mechanical many-body system composed of indistinguishable particles distributed over a multitude of modes is one of the paradigmatic test cases of…
The semiclassical propagator in fermionic Fock space
Thomas Engl, Peter Plößl, Juan Diego Urbina +1
We present a rigorous derivation of a semiclassical propagator for anticommuting (fermionic) degrees of freedom, starting from an exact representation in terms of Grassmann variabl…
Many-Body Spin Echo
Thomas Engl, Juan Diego Urbina, Klaus Richter +1
We predict a universal echo phenomenon present in the time evolution of many-body states of interacting quantum systems described by Fermi-Hubbard models. It consists of the cohere…
Multiparticle correlations in mesoscopic scattering: boson sampling, birthday paradox, and Hong-Ou-Mandel profiles
Juan-Diego Urbina, Jack Kuipers, Quirin Hummel +2
The interplay between single-particle interference and quantum indistinguishability leads to signature correlations in many-body scattering. We uncover these with a semiclassical c…
