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…
