We propose a cold-atom realization of a zigzag ladder. The two legs of the ladder
correspond to a “synthetic” dimension given by two internal (spin) states of the atoms, so that …

We present a technique that enables the evaluation of perturbative expansions based on
one-loop-renormalized vertices up to large expansion orders. Specifically, we show how to …

We study the Hubbard model with time-reversal-invariant flux and spin-orbit coupling and
position-dependent onsite energies on the kagome lattice, using numerical and analytical …

In this dissertation we focus on many-body phenomena on a quantum level. In particular
fermionic quantum gases in a temperature regime approaching absolute zero. Ultracold …
