Nonlocal Quantum Phase Transitions
Alessandro Coppo, Aanal Jayesh Shah, Hadiseh Alaeian +3
Phase transitions are paradigmatic examples of emergent phenomena, in which symmetries present at the microscopic level can be spontaneously broken in the thermodynamic limit. Two…
Cuprate Twistronics for Quantum Hardware
Tommaso Confalone, Flavia Lo Sardo, Yejin Lee +12
Recent advances in the manipulation of complex oxide layers, particularly the fabrication of atomically thin cuprate superconducting films via molecular beam epitaxy, have revealed…
Collective quantum enhancement in critical quantum sensing
Uesli Alushi, Alessandro Coppo, Valentina Brosco +2
Critical systems represent a valuable resource in quantum sensing and metrology. Critical quantum sensing (CQS) protocols can be realized using finite-component phase transitions,…
Nonlinearity-driven Topology via Spontaneous Symmetry Breaking
Alessandro Coppo, Alexandre Le Boité, Simone Felicetti +1
Topology and nonlinearity are deeply connected. However, whether topological effects can arise solely from the structure of nonlinear interaction terms, and the nature of the resul…
