Transport of ultracold dipolar fermions in one-dimensional optical lattices
Barnali Chakrabarti, N D Chavda, Andrea Trombettoni +1
We investigate the transport properties in out-of-equilibrium dynamics of strongly correlated dipolar fermions initially localized in one-dimensional inhomogeneous optical lattice.…
Dynamical Phase Diagram of Ultracold Josephson Junctions
K. Xhani, L. Galantucci, C. F. Barenghi +3
We provide a complete study of the phase diagram characterising the distinct dynamical regimes emerging in a three-dimensional Josephson junction in an ultracold quantum gas. Consi…
Synthesis of Majorana mass terms in low-energy quantum systems
L. Lepori, A. Celi, A. Trombettoni +1
We discuss the problem of how Majorana mass terms can be generated in low-energy systems. We show that, while these terms imply the Majorana condition, the opposite is not always t…
Excitations and stability of weakly interacting Bose gases with multi-body interactions
D. Laghi, T. Macrì, A. Trombettoni
We consider weakly interacting bosonic gases with local and non-local multi-body interactions. By using the Bogoliubov approximation, we first investigate contact interactions, stu…
-function and central charge of the sine-Gordon model from the non-perturbative renormalization group flow
V. Bacsó, N. Defenu, A. Trombettoni +1
In this paper we study the -function of the sine-Gordon model taking explicitly into account the periodicity of the interaction potential. The integration of the -function al…
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…
Semimetal-superfluid quantum phase transitions in 2D and 3D lattices with Dirac points
Gabriel Mazzucchi, Luca Lepori, Andrea Trombettoni
We study the superfluid properties of attractively interacting fermions hopping in a family of 2D and 3D lattices in the presence of synthetic gauge fields having π-flux per plaque…
Relative Phase and Josephson Dynamics between Weakly Coupled Richardson Models
F. Buccheri, A. Trombettoni
We consider two weakly coupled Richardson models to study the formation of a relative phase and the Josephson dynamics between two mesoscopic attractively interacting fermionic sys…
Anisotropic Ginzburg-Landau and Lawrence-Doniach Models for Layered Ultracold Fermi Gases
Mauro Iazzi, Stefano Fantoni, Andrea Trombettoni
We study the anisotropic Ginzburg-Landau and Lawrence-Doniach models describing a layered superfluid ultracold Fermi gas in optical lattices. We derive the coefficients of the anis…
Phase Structure and Compactness
I. Nandori, S. Nagy, K. Sailer +1
In order to study the influence of compactness on low-energy properties, we compare the phase structures of the compact and non-compact two-dimensional multi-frequency sine-Gordon…
Tunneling of polarized fermions in 3D double wells
Tommaso Macri, Andrea Trombettoni
We study the tunneling of a spin polarized Fermi gas in a three-dimensional double well potential, focusing on the time dynamics starting from an initial state in which there is an…
Relativistic Bose-Einstein Condensates: a new system for analogue models of gravity
Serena Fagnocchi, Stefano Finazzi, Stefano Liberati +2
In this paper we propose to apply the analogy between gravity and condensed matter physics to relativistic Bose-Einstein condensates (RBECs), i.e. condensates composed by relativis…
Dynamical Superfluid-Insulator Transition in a Chain of Weakly Coupled Bose-Einstein Condensates
A. Smerzi, A. Trombettoni, P. G. Kevrekidis +1
We predict a dynammical classical superfluid-insulator transition (CSIT) in a Bose-Einstein condensate (BEC) trapped in an optical and a magnetic potential. In the tight-binding li…
Discrete Solitons and Breathers with Dilute Bose-Einstein Condensates
A. Trombettoni, A. Smerzi
We study the dynamical phase diagram of a dilute Bose-Einstein condensate (BEC) trapped in a periodic potential. The dynamics is governed by a discrete non-linear Schrödinger equat…
