Frustrated quantum spin systems in small triangular lattices studied with a numerical method
D. Castells-Graells, A. Yuste, A. Sanpera
The study of quantum frustrated systems remains one of the most challenging subjects of quantum magnetism, as they can hold quantum spin liquids, whose characterization is quite el…
Entanglement scaling at first order phase transitions
A. Yuste, C. Cartwright, G. De Chiara +1
First order quantum phase transitions (1QPTs) are signaled, in the thermodynamic limit, by discontinuous changes in the ground state properties. These discontinuities affect expect…
Using Random Boundary Conditions to simulate disordered quantum spin models in 2D-systems
A. Yuste, M. Moreno-Cardoner, A. Sanpera
Disordered quantum antiferromagnets in two-dimensional compounds have been a focus of interest in the last years due to their exotic properties. However, with very few exceptions,…
Mesoscopic superpositions of Tonks-Girardeau states and the Bose-Fermi mapping
M. A. García-March, A. V. Yuste-Roca, B. Juliá-Díaz +1
We study a one dimensional gas of repulsively interacting ultracold bosons trapped in a double-well potential as the atom-atom interactions are tuned from zero to infinity. We conc…
Shortcut to adiabaticity in internal bosonic Josephson junctions
A. Yuste, B. Juliá-Díaz, E. Torrontegui +3
We extend a recent method to shortcut the adiabatic following to internal bosonic Josephson junctions in which the control parameter is the linear coupling between the modes. The a…
