Capturing magic angles in twisted bilayer graphene from information theory markers
Manuel Calixto, Alberto Mayorgas, Octavio Castaños
Zero energy eigenstates of the twisted bilayer graphene Hamiltonian at the Dirac point show a high sensitivity to the twist angle near the magic angles where the effec…
Localization and entanglement characterization of edge states in HgTe quantum wells in a finite strip geometry
Manuel Calixto, Octavio Castaños
Quantum information measures are proposed to analyze the structure of near-gap electronic states in HgTe quantum wells in a strip geometry o…
GKLS Vector Field Dynamics for Gaussian States
Hans Cruz-Prado, Octavio Castaños, Giuseppe Marmo +1
We construct the vector field associated to the GKLS generator for systems described by Gaussian states. This vector field is defined on the dual space of the algebra of operators,…
Quantum revivals in HgTe/CdTe quantum wells and topological phase transitions
A. Mayorgas, M. Calixto, N. A. Cordero +2
The time evolution of a wave packet is a tool to detect topological phase transitions in two-dimensional Dirac materials, such as graphene and silicene. Here we extend the analysis…
Faraday rotation and transmittance as markers of topological phase transitions in 2D materials
M. Calixto, A. Mayorgas, N. A. Cordero +2
We analyze the magneto-optical conductivity (and related magnitudes like transmittance and Faraday rotation of the irradiated polarized light) of some elemental two-dimensional Dir…
Fidelity, entropy, and Poincaré sections as tools to study the polyad breaking phenomena
M. Bermúdez-Montaña, R. Lemus, O. Castaños
The correlation diagram of the vibrational energy spectra associated with the stretching modes of triatomic molecules such as CO and HO is analyzed by means of two interact…
Searching for pairing energies in phase space
M. Calixto, O. Castaños, E. Romera
We obtain a representation of pairing energies in phase space, for the Lipkin-Meshkov-Glick and general boson Bardeen-Cooper-Schrieffer pairing models. This is done by means of a p…
Fidelity, susceptibility and critical exponents in the Dicke model
M. A. Bastarrachea-Magnani, O. Castaños, E. Nahmad-Achar +2
We calculate numerically the fidelity and its susceptibility for the ground state of the Dicke model. A minimum in the fidelity identifies the critical value of the interaction whe…
Neutrinoless Double Beta Decay in Heavy Deformed Nuclei
Jorge G. Hirsch, O. Castaños, P. O. Hess
The zero neutrino mode of the double beta decay in heavy deformed nuclei is investigated in the framework of the pseudo SU(3) model, which has provided an accurate description of c…
