Electron Shuttle Waiting Times for Electric Field Sensing
Alberto Mayorgas, Alberto López-GarcÃa, 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-GarcÃa, 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, Ãlvaro 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 ef…
