Emergent BEC mechanism in flat-band superconductors
V. Berger, I. S. Tupitsyn, B. Currie +3
The formation of bound bosonic pairs of fermions, followed by their Bose-Einstein (quasi) condensation (BEC), is a foundational mechanism of superconductivity. At low filling, flat…
Low-temperature Depletion of Superfluid Density in the Absence of Galilean Symmetry
Viktor Berger, Nikolay Prokof'ev, Boris Svistunov
Landau theory of superfluidity associates low-temperature flow of the normal component with the phonon wind. This picture does not apply to superfluids in which Galilean invariance…
"Depletion" of Superfluid Density: Universal Low-temperature Thermodynamics of Superfluids
Viktor Berger, Nikolay Prokof'ev, Boris Svistunov
In a Galilean superfluid, the depletion of superfluid density with rising temperature can be attributed to thermally excited non-interacting phonons. For systems without Galilean s…
Numerical Study of Disordered Noninteracting Chains Coupled to a Local Lindblad Bath
Viktor Berger, Andrea Nava, Jens H. Bardarson +1
Disorder can prevent many-body quantum systems from reaching thermal equilibrium, leading to a many-body localized phase. Recent works suggest that nonperturbative effects caused b…
