Steady-state properties of a thermodynamically unbalanced Fermi gas
Pedro Ribeiro
The current-carrying steady-state that arises in the middle of a metallic wire connected to macroscopic leads is characterized regarding its response functions, correlations and en…
Post-quench dynamics and suppression of thermalization in an open half-filled Hubbard layer
Igor V. Blinov, Pedro Ribeiro, A. N. Rubtsov
We study the time evolution of a half-filled Hubbard layer coupled to a magnon bath after a quench of the Hubbard interaction. Qualitatively different regimes, regarding the asympt…
Role of coherence in transport through engineered atomic spin devices
Alexey M. Shakirov, Yulia E. Shchadilova, Alexey N. Rubtsov +1
We give a further step in the quantum mechanical description of engineered atomic spin structures by deriving a master equation of the Redfield type that governs the dynamics of th…
The Functional Integral formulation of the Schrieffer-Wolff transformation
Farzaneh Zamani, Pedro Ribeiro, Stefan Kirchner
We revisit the Schrieffer-Wolff transformation and present a path integral version of this important canonical transformation. The equivalence between the low-energy sector of the…
Interaction-tuned Anderson versus Mott localization
Andrey E. Antipov, Younes Javanmard, Pedro Ribeiro +1
Disorder or sufficiently strong interactions can render a metallic state unstable causing it to turn into an insulating one. Despite the fact that the interplay of these two routes…
Transient phases and dynamical transitions in the post quench evolution of the generalized Bose-Anderson model
Dmitry V. Chichinadze, Pedro Ribeiro, Yulia E. Shchadilova +1
The exact description of the time evolution of open correlated quantum systems remains one of the major challenges of the condensed matter theory, specially for asymptotic long tim…
