Localization of interacting Fermi gases in quasiperiodic potentials
Sebastiano Pilati, Vipin Kerala Varma
We investigate the zero-temperature metal-insulator transition in a one-dimensional two-component Fermi gas in the presence of a quasi-periodic potential resulting from the superpo…

Renormalization of two-body interactions due to higher-body interactions of lattice bosons
Vipin Kerala Varma, Hartmut Monien
We calculate thermodynamic properties of soft-core lattice bosons with on-site -body interactions using up to twelfth and tenth order strong coupling expansion in one and two di…
