Two-time Correlations Probing the Dynamics of Dissipative Many-Body Quantum Systems: Aging and Fast Relaxation
Bruno Sciolla, Dario Poletti, Corinna Kollath
Two-time correlations are a crucial tool to probe the dynamics of many-body systems. We use these correlation functions to study the dynamics of dissipative quantum systems. Extend…
Dissipative quantum dynamics of fermions in optical lattices: a slave-spin approach
Jean-Sebastien Bernier, Dario Poletti, Corinna Kollath
We investigate the influence of a Markovian environment on the dynamics of interacting spinful fermionic atoms in a lattice. In order to explore the physical phenomena occurring at…
Exploring Unconventional Hubbard Models with Doubly Modulated Lattice Gases
Sebastian Greschner, Luis Santos, Dario Poletti
Recent experiments show that periodic modulations of cold atoms in optical lattices may be used to engineer and explore interesting models. We show that double modulation, combinin…
Work and Efficiency of Quantum Otto Cycles in Power Law Trapping Potentials
Yuanjian Zheng, Dario Poletti
We study the performance of a quantum Otto cycle driven by trapping potentials of the form . This family of potentials possesses a simple scaling property which…
