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…
Superconducting dome due to the Fano-Feshbach shape resonance in artificial high-Tc superlattices
Gaetano Campi, Andrea Alimenti, Danielle Villa +7
In this work we provide compelling experimental validation of the Bianconi Perali Valletta (BPV) theory predicting a superconducting dome based on a quantum material design of Arti…
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…
Berezinskii-Kosterlitz-Thouless transition with enhanced phase stiffness in -wave strongly coupled two-dimensional superconductors
Sathish Kumar Paramasivam, Andrea Perali, Milorad V. MiloÅ¡eviÄ
We reveal the key role of the -wave symmetry of the superconducting gap in strongly coupled two-dimensional superconductors in determining the properties of the Berezinskii-Kost…
Beyond Random Phase Approximation in electron-hole bilayer superfluidity
Filippo Pascucci, Stefania De Palo, Sara Conti +3
We derive the normal and anomalous proper polarization functions and the screened Coulomb interactions in a two-dimensional superfluid electron-hole bilayer, including all first-or…
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…
