Quantum Impurities as Probes of Finite-Temperature Fluctuations in Two-Dimensional Bose Gases

Victor Velasco, Gabriele Spada, Giovanni Midei +2

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…

Pairing amplification induced by nonadiabatic effects on the electron-phonon interaction throughout the BCS-BEC crossover

Victor Velasco, Giovanni Midei, Massimo Capone +1

Nonadiabatic effects in the electron-phonon coupling are important whenever the ratio between the phononic and the electronic energy scales, the adiabatic ratio, is non negligible.…

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…

Predictive power of the Berezinskii-Kosterlitz-Thouless theory based on Renormalization Group throughout the BCS-BEC crossover in 2D superconductors

Giovanni Midei, Koichiro Furutani, Luca Salasnich +1

Recent experiments on 2D superconductors allow the characterization of the critical temperature and of the phase diagram across the BCS-BEC crossover as a function of density. We o…

Tunable BCS-BEC crossover, reentrant, and hidden quantum phase transitions in two-band superconductors with tunable valence and conduction bands

Giovanni Midei, Andrea Perali

Two-band electronic structures with a valence and a conduction band separated by a tunable energy gap and with pairing of electrons in different channels can be relevant to investi…
