Temporal bistability in the dissipative Dicke-Bose-Hubbard system
Tianyi Wu, Sayak Ray, Johann Kroha
We consider a driven-dissipative system consisting of an atomic Bose-Einstein condensates loaded into a two-dimensional Hubbard lattice and coupled to a single mode of an optical c…
Non-Markovian Dynamics of Open Quantum Systems via Auxiliary Particles with Exact Operator Constraint
Tim Bode, Michael Kajan, Francisco Meirinhos +1
We introduce an auxiliary-particle field theory to treat the non-Markovian dynamics of driven-dissipative quantum systems of the Jaynes-Cummings type. It assigns an individual quan…
ARPES signature of the competition between magnetic order and Kondo effect in CeCoGe3
Peng Li, Huiqing Ye, Yong Hu +16
The competition between magnetic order and Kondo effect is essential for the rich physics of heavy fermion systems. Nevertheless, how such competition is manifested in the quasipar…
Asymmetry effects on the phases of RKKY-coupled two-impurity Kondo systems
Krzysztof P. Wójcik, Johann Kroha
In a related work [arXiv:2106.07519] we have shown that in the two-impurity Anderson (2iA) model with two hosts coupled by spin exchange in the most symmetric case there are either…
Critical slowing down of fermions near a magnetic quantum phase transition
Chia-Jung Yang, Kristin Kliemt, Cornelius Krellner +3
A universal phenomenon in phase transitions is critical slowing down (CSD) - systems, after an initial perturbation, take an exceptionally long time to return to equilibrium. It is…
Classical route to ergodicity and scarring phenomena in a two-component Bose-Josephson junction
Debabrata Mondal, Sudip Sinha, Sayak Ray +2
We consider a Bose-Josephson junction (BJJ) formed by a binary mixture of ultracold atoms to investigate the manifestation of coherent collective dynamics on ergodicity and quantum…
