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…
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…
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…
