Emergent Dimensionality in Diluted Power-Law Quantum Walks
G. A. Domínguez-Castro, L. Santos
We investigate single-excitation quantum walks across the one-to-two-dimensional crossover in diluted power-law hopping models. Using arrays of coupled chains of length ,…
Polarons and bipolarons in Rydberg-dressed extended Bose-Hubbard model
G. A. Domínguez-Castro, L. Santos, L. A. Peña Ardila
Impurities immersed in hard-core Bose gases offer exciting opportunities to explore polaron and bipolaron physics. We investigate the ground state properties of a single and a pair…
Emergent interaction-induced topology in Bose-Hubbard ladders
David Wellnitz, Gustavo A. Domínguez-Castro, Thomas Bilitewski +3
We investigate the quantum many-body dynamics of bosonic atoms hopping in a two-leg ladder with strong on-site contact interactions. We observe that when the atoms are prepared in…
Topological floating phase of dipolar bosons in an optical ladder
Henning Korbmacher, Gustavo A. Domínguez-Castro, Mateusz Łącki +2
Ultracold dipolar hard-core bosons in optical ladders provide exciting possibilities for the quantum simulation of anisotropic XXZ spin ladders. We show that introducing a tilt alo…
Momentum-selective pair creation of spin excitations in dipolar bilayers
Thomas Bilitewski, G. A. Domínguez-Castro, David Wellnitz +2
We study the temporal growth and spatial propagation of quantum correlations in a two-dimensional bilayer realising a spin-1/2 quantum XXZ model with couplings mediated by long-ran…
Polarons and bipolarons in a two-dimensional square lattice
Shanshan Ding, G. A. Domínguez-Castro, Aleksi Julku +2
Quasiparticles and their interactions are a key part of our understanding of quantum many-body systems. Quantum simulation experiments with cold atoms have in recent years advanced…
Localization of Pairs in One-Dimensional Quasicrystals with Power-Law Hopping
G. A. Domínguez-Castro, R. Paredes
Pair localization in one-dimensional quasicrystals with nearest-neighbor hopping is independent of whether short-range interactions are repulsive or attractive. We numerically demo…
Quantum walkers in a disordered lattice with power-law hopping
G. A. Domínguez-Castro, R. Paredes
We study the effects of interparticle interactions and power-law tunneling couplings on quantum walks executed by both a single one and a pair of hard-core bosons moving in clean a…
Relaxation of ferromagnetic domains in a disordered lattice in 2D
C. Madroñero, G. A. Domínguez-Castro, L. A. González-García +1
We investigate the relaxation process of ferromagnetic domains in 2D subjected to the influence of both, static disorder of variable strength and weak interactions. The domains are…
