Parity-dependent double degeneracy and spectral statistics in the projected dice lattice
Koushik Swaminathan, Anouar Moustaj, Jose L. Lado +1
We investigate the spectral statistics of an interacting fermionic system derived by projecting the Hubbard interaction onto the two lowest-energy, degenerate flat bands of the dic…
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…
Signatures of many-body localization of quasiparticles in a flat band superconductor
Koushik Swaminathan, Poula Tadros, Sebastiano Peotta
We construct a class of exact eigenstates of the Hamiltonian obtained by projecting the Hubbard interaction term onto the flat band subspace of a generic lattice model. These exact…
