Competing many-body interactions in systems of trapped ions
A. Bermudez, D. Porras, M. A. Martin-Delgado
We propose and theoretically analyse an experimental configuration in which lasers induce 3-spin interactions between trapped ions.By properly choosing the intensities and frequenc…
Unifying all classical spin models in a Lattice Gauge Theory
G. De las Cuevas, W. Dür, H. J. Briegel +1
We show that the partition function of all classical spin models, including all discrete Standard Statistical Models and all abelian discrete Lattice Gauge Theories (LGTs), can be…
Topology induced anomalous defect production by crossing a quantum critical point
A. Bermudez, D. Patanè, L. Amico +1
We study the influence of topology on the quench dynamics of a system driven across a quantum critical point. We show how the appearance of certain edge states, which fully charact…
VBS State Induced by Impurity Frustration in Cr8Ni
J. Almeida, M. A. Martin-Delgado, G. Sierra
We provide a physically meaningful picture of the nature of the ground state of the Cr8Ni compound in the regime where it is a spin singlet. According to this picture, the anisotro…
Chirality Quantum Phase Transition in the Dirac oscillator
A. Bermudez, M. A. Martin-Delgado, A. Luis
We study a relativistic spin-1/2 fermion subjected to a Dirac oscillator coupling and a constant magnetic field. An interplay between opposed chirality interactions culminates in t…
Twisted Order Parameter applied to Dimerized Ladders
J. Almeida, M. A. Martin-Delgado, G. Sierra
We apply the twisted order parameter (TOP) for dimerized quantum spin ladders to locate the critical phases that separate gapped phases representing quantum spin liquids of various…
