Hidden Magnetism in Periodically Modulated One Dimensional Dipolar Fermions
S. Fazzini, A. Montorsi, M. Roncaglia +1
The experimental realization of time dependent ultracold lattice systems has paved the way towards the implementation of new Hubbard-like Hamiltonians. We show that in a one dimens…
Strongly correlated states of trapped ultracold fermions in deformed Landau levels
M. Burrello, M. Rizzi, M. Roncaglia +1
We analyze the strongly correlated regime of a two-component trapped ultracold fermionic gas in a synthetic non-Abelian U(2) gauge potential, that consists of both a magnetic field…
From Rotating Atomic Rings to Quantum Hall States
Marco Roncaglia, Matteo Rizzi, Jean Dalibard
Considerable efforts are currently devoted to the preparation of ultracold neutral atoms in the emblematic strongly correlated quantum Hall regime. The routes followed so far essen…
Effective mapping of spin-1 chains onto integrable fermionic models. A study of string and Neel correlation functions
C. Degli Esposti Boschi, M. Di Dio, G. Morandi +1
We derive the dominant contribution to the large-distance decay of correlation functions for a spin chain model that exhibits both Haldane and Neel phases in its ground state phase…
The dimer-RVB State of the Four-Leg Heisenberg Ladder: Interference among Resonances
M. Roncaglia, G. Sierra, M. A. Martin-Delgado
We study the ground state of the 4-leg spin ladder using a dimer-RVB ansatz and the Lanczos method. Besides the well known resonance mechanism between valence bond configurations w…
