Open quantum systems in thermal non-ergodic environments
Carlos A. Parra-Murillo, Max Bramberger, Claudius Hubig +1
The dynamics of an open system crucially depends on the correlation function of its environment, . We show that for thermal non-Harmonic environments may not decay…
Occupation-constrained interband dynamics of a non-hermitian two-band Bose-Hubbard Hamiltonian
Manuel H. Muñoz-Arias, Carlos A. Parra-Murillo, Javier Madroñero +1
The interband dynamics of a two-band Bose-Hubbard model is studied with strongly correlated bosons forming single-site double occupancies referred to as doublons. Our model for res…
Generation of robust entangled states in a non-hermitian periodically driven two-band Bose-Hubbard system
Carlos A. Parra-Murillo, Manuel H. Muñoz-Arias, Javier Madroñero +1
A many-body Wannier-Stark system coupled to an effective reservoir is studied within a non-Hermitian approach in the presence of a periodic driving. We show how the interplay of di…
Off-resonant many-body quantum carpets in strongly tilted optical lattices
Manuel H. Muñoz-Arias, Javier Madroñero, Carlos A. Parra-Murillo
An unit filling Bose-Hubbard Hamilonian embedded in strong Stark field is studied in the off-resonant regime inhibiting single and many-particle first order tunneling resonances. W…
Exact numerical methods for a many-body Wannier Stark system
Carlos A. Parra-Murillo, Javier Madroñero, Sandro Wimberger
We present exact methods for the numerical integration of the Wannier-Stark system in a many-body scenario including two Bloch bands. Our ab initio approaches allow for the treatme…
Power dependence of Klyshko's Stokes-anti-Stokes correlation in the inelastic scattering of light
Carlos A. Parra-Murillo, Marcelo F. Santos, Carlos H. Monken +1
The Stokes and anti-Stokes components in the inelastic scattering of light are related to phonon statistics and have been broadly used to measure temperature and phonon lifetimes i…
Quantum diffusion and thermalization at resonant tunneling
Carlos A. Parra-Murillo, Javier Madroñero, Sandro Wimberger
Nonequilibrium dynamics and effective thermalization are studied in a resonant tunneling scenario via multilevel Landau-Zener crossings. Our realistic many-body system, composed of…
Non-hermitian approach to decaying ultracold bosonic systems
S. Wimberger, C. A. Parra-Murillo, G. Kordas
A paradigm model of modern atom optics is studied, strongly interacting ultracold bosons in an optical lattice. This many-body system can be artificially opened in a controlled man…
A two-band Bose-Hubbard model for many-body resonant tunneling in the Wannier-Stark system
Carlos A. Parra-Murillo, Javier Madroñero, Sandro Wimberger
We study an experimentally realizable paradigm of complex many-body quantum systems, a two-band Wannier-Stark model, for which diffusion in Hilbert space as well as many-body Landa…
