Dissipative framework for subsystem dynamics of noninteracting quantum chains
Michele Coppola, Zala Lenarčič
When only local observables of a many-body quantum system are of interest, it is desirable to formulate a reduced description within the Hilbert space of the corresponding subsyste…
Learning the non-Markovian features of subsystem dynamics
Michele Coppola, Mari Carmen Bañuls, Zala LenarÄiÄ
The dynamics of local observables in a quantum many-body system can be formally described in the language of open systems. The problem is that the bath representing the complement…
A Hubbard exciton fluid in a photo-doped antiferromagnetic Mott insulator
Omar Mehio, Xinwei Li, Honglie Ning +7
The undoped antiferromagnetic Mott insulator naturally has one charge carrier per lattice site. When it is doped with additional carriers, they are unstable to spin fluctuation-med…
Generalized Gibbs ensembles in weakly interacting dissipative systems and digital quantum computers
Iris UlÄakar, Zala LenarÄiÄ
Identifying use cases with superconducting circuits not critically affected by the inherent noise is a pertinent challenge. Here, we propose using a digital quantum computer to sho…
