Supersolid phase in two-dimensional soft-core bosons at finite temperature
Sebastiano Peotta, Gabriele Spada, Stefano Giorgini +2
The supersolid phase of soft-core bosons in two dimensions is investigated using the self-consistent Hartree-Fock and quantum Monte Carlo methods. An approximate phase diagram at f…
Quantum geometry in superfluidity and superconductivity
Sebastiano Peotta, Kukka-Emilia Huhtinen, Päivi Törmä
We review the theoretical description of the role of quantum geometry in superfluidity and superconductivity of multiband systems, with focus on flat bands where quantum geometry i…
Flat band transport and Josephson effect through a finite-size sawtooth lattice
Ville A. J. Pyykkönen, Sebastiano Peotta, Philipp Fabritius +3
We study theoretically the transport through a finite-size sawtooth lattice coupled to two fermionic reservoirs kept in the superfluid state. We focus on the DC Josephson effect an…
Flat band induced non-Fermi liquid behavior of multicomponent fermions
Pramod Kumar, Sebastiano Peotta, Yosuke Takasu +2
We investigate multicomponent fermions in a flat band and predict experimental signatures of non-Fermi liquid behavior. We use dynamical mean-field theory to obtain the density, do…
Spin-Imbalanced Pairing and Fermi Surface Deformation in Flat Bands
Kukka-Emilia Huhtinen, Marek Tylutki, Pramod Kumar +3
We study the attractive Hubbard model with spin imbalance on two lattices featuring a flat band: the Lieb and kagome lattices. We present mean-field phase diagrams featuring exotic…
