Parity-dependent double degeneracy and spectral statistics in the projected dice lattice
Koushik Swaminathan, Anouar Moustaj, Jose L. Lado +1
The paper studies how the energy levels of a fermionic system on a dice lattice with π‑flux behave, finding that even and odd particle numbers follow different random‑matrix statis…
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…
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…
Coexistence of ergodic and non-ergodic behavior and level spacing statistics in a one-dimensional model of a flat band superconductor
Meri Teeriaho, Ville-Vertti Linho, Koushik Swaminathan +1
Motivated by recent studies of the projected dice lattice Hamiltonian [K. Swaminathan et al., Phys. Rev. Research 5, 043215 (2023)], we introduce the on-site/bond singlet (OBS) mod…
