Quantum Impurities as Probes of Finite-Temperature Fluctuations in Two-Dimensional Bose Gases
Victor Velasco, Gabriele Spada, Giovanni Midei +3
Two-dimensional quantum gases provide a distinctive setting in which enhanced thermal fluctuations, finite-size effects, and two-body bound-state formation are intrinsically intert…
Signature in sound-mode of the exciton bilayer two-dimensional superfluid transition
Giovanni Midei, Filippo Pascucci, Milorad V. Milosevìc +3
Obtaining definitive evidence of exciton superfluidity in electron-hole bilayers in zero magnetic field remains a major longstanding challenge since the condensate is electrically…
Confinement and finite-range effects in a quasi-two-dimensional gas of fermionic dimers
Giovanni Midei, Jordi Boronat, Grigory E. Astrakharchik
We investigate the ground-state properties of ultracold two-component Fermi gases in the presence of a transverse harmonic potential, focusing on the strongly interacting regime in…
Upper critical magnetic field and multiband superconductivity in artificial high-Tc superlattices of nano quantum wells
G. Campi, A. Alimenti, G. Logvenov +10
Artificial high-Tc superlattices (AHTS) composed of quantum building blocks with tunable superconducting critical temperature have been synthesized by engineering their nanoscale g…
Amplitude, phase, and topological fluctuations shaping the complex phase diagram of two-dimensional superconductors
Koichiro Furutani, Giovanni Midei, Andrea Perali +1
We study the amplitude and phase fluctuations of the Ginzburg-Landau quasiorder parameter for superconductors in two spatial dimensions. Starting from the mean-field critical tempe…
