Hilbert Space Black Hole Analog: Unidirectional Transport without Driving
Elvira Bilokon, Valeriia Bilokon, Frank Großmann +2
Black holes permit matter to cross their event horizon in only one direction. We show that interacting bosons in optical lattices with asymmetric barrier exhibit an analogous pheno…
Revealing quantum effects in bosonic Josephson junctions: a multi-configuration atomic coherent states approach
Yulong Qiao, Frank Grossmann
The mean-field approach to two-site Bose-Hubbard systems is well established and leads to nonlinear classical equations of motion for the population imbalance and the phase differe…
Entanglement in the full state vector of boson sampling
Yulong Qiao, Joonsuk Huh, Frank Grossmann
The full state vector of boson sampling is generated by passing S single photons through beam splitters of M modes. The initial Fock state is expressed withgeneralized coherent sta…
Non-Markovian Vibrational Relaxation Dynamics at Surfaces
Eric W. Fischer, Michael Werther, Foudhil Bouakline +2
Vibrational dynamics of adsorbates near surfaces plays both an important role for applied surface science and as model lab for studying fundamental problems of open quantum systems…
Quantum approach to the thermalization of the toppling pencil interacting with a finite bath
Sreeja Loho Choudhury, Frank Grossmann
We investigate the longstanding problem of thermalization of quantum systems coupled to an environment by focusing on a bistable quartic oscillator interacting with a finite number…
Schrödinger-cat states in Landau-Zener-Stückelberg-Majorana interferometry: a multiple Davydov Ansatz approach
Lu Wang, Fulu Zheng, Jiaming Wang +2
Employing the time-dependent variational principle combined with the multiple Davydov Ansatz, we investigate Landau-Zener (LZ) transitions in a qubit coupled to a ph…
