Electron Shuttle Waiting Times for Electric Field Sensing

Alberto Mayorgas, Alberto López-García, Enamul Haque +1

We explore the use of waiting-time statistics in a quantum electron shuttle for electric-field sensing. Electron shuttles convert nanomechanical motion into charge transport, showi…

Fast Arbitrary Qutrit Gates for NV Centers in the Low-Field Regime

Alberto López-García, Marcel Morillas-Rozas, Alberto Mayorgas +1

The ground state of the negatively charged NV center forms a spin-1 manifold providing a versatile platform for sensing and information processing. Here we present a scheme for imp…

Excited-state quantum phase transitions and chaos in a three-level Lipkin model

Alberto Mayorgas, Pedro Pérez-Fernández, Álvaro Sáiz +1

Excited-state quantum phase transitions (ESQPTs) have been extensively studied in two-level models, but their characterization remains challenging in systems displaying mixed regul…

Lieb-Mattis ordering theorem of electronic energy levels in the thermodynamic limit

Manuel Calixto, Alberto Mayorgas, Julio Guerrero

Lieb-Mattis theorem orders the lowest-energy states of total spin of a system of interacting fermions. We generalize these predictions to fermionic mixtures of particle…

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…

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…

Localization measures of parity adapted U()-spin coherent states applied to the phase space analysis of the -level Lipkin-Meshkov-Glick model

Alberto Mayorgas, Julio Guerrero, Manuel Calixto

We study phase-space properties of critical, parity symmetric, -quDit systems undergoing a quantum phase transition (QPT) in the thermodynamic limit. The leve…

Schmidt decomposition of parity adapted coherent states for symmetric multi-quDits

Julio Guerrero, Antonio Sojo, Alberto Mayorgas +1

In this paper we study the entanglement in symmetric -quDit systems. In particular we use generalizations to of spin coherent states and their projections on defin…

Information diagrams in the study of entanglement in symmetric multi-quDit systems and applications to quantum phase transitions in Lipkin-Meshkov-Glick D-level atom models

Julio Guerrero, Alberto Mayorgas, Manuel Calixto

In this paper we pursue the use of information measures (in particular, information diagrams) for the study of entanglement in symmetric multi-quDit systems. We use generalizations…

Entanglement and U(D)-spin squeezing in symmetric multi-quDit systems and applications to quantum phase transitions in Lipkin-Meshkov-Glick D-level atom models

Manuel Calixto, Alberto Mayorgas, Julio Guerrero

Collective spin operators for symmetric multi-quDit (namely, identical -level atom) systems generate a U symmetry. We explore generalizations to arbitrary of SU(2)-spin…

Role of mixed permutation symmetry sectors in the thermodynamic limit of critical three-level Lipkin-Meshkov-Glick atom models

M. Calixto, A. Mayorgas, J. Guerrero

We introduce the notion of Mixed Symmetry Quantum Phase Transition (MSQPT) as singularities in the transformation of the lowest-energy state properties of a system of identical par…
