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…
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…
