Population annealing with topological defect driven nonlocal updates for spin systems with quenched disorder

Cirauqui, David; Garcia March, Miguel Angel; Saavedra, J.R.M.; Lewenstein, Maciej; Grzybowski, Przemyslaw R. (American Physical Society, 2024-04-11)

[EN] Population annealing, one of the currently state-of-the-art algorithms for solving spin -glass systems, sometimes finds hard disorder instances for which its equilibration quality at each temperature step is severely ...
Symplectic time-average propagators for the Schrodinger equation with a time-dependent Hamiltonian

Blanes Zamora, Sergio; Casas, Fernando; Murua, Ander (American Institute of Physics, 2017-03-21)

[EN] Several symplectic splitting methods of orders four and six are presented for the step-by-step time numerical integration of the Schrodinger equation when the Hamiltonian is a general explicitly time-dependent real ...
Two distinguishable impurities in BEC: squeezing and entanglement of two Bose polarons

Charalambous, Christos; Garcia March, Miguel Angel; Lampo, Aniello; Mehboudi, Mohammad; Lewenstein, Maciej (SciPost Foundation, 2019-01)

[EN] We study entanglement and squeezing of two uncoupled impurities immersed in a Bose-Einstein condensate. We treat them as two quantum Brownian particles interacting with a bath composed of the Bogoliubov modes of the ...
