Signatures of topology in quantum quench dynamics and their interrelation
Lorenzo Pastori, Simone Barbarino, Jan Carl Budich
Motivated by recent experimental progress in the study of quantum systems far from equilibrium, we investigate the relation between several dynamical signatures of topology in the…
Preparing Atomic Topological Quantum Matter by Adiabatic Nonunitary Dynamics
S. Barbarino, J. Yu, P. Zoller +1
Motivated by the outstanding challenge of realizing low-temperature states of quantum matter in synthetic materials, we propose and study an experimentally feasible protocol for pr…
First-Order Topological Quantum Phase Transition in a Strongly Correlated Ladder
S. Barbarino, G. Sangiovanni, J. C. Budich
We report on the discovery of a quantum tri-critical point (QTP) separating a line of first-order topological quantum phase transitions from a continuous transition regime in a str…
Topological Devil's staircase in atomic two-leg ladders
S. Barbarino, D. Rossini, M. Rizzi +3
We show that a hierarchy of topological phases in one dimension -- a topological Devil's staircase -- can emerge at fractional filling fractions in interacting systems, whose singl…
Engineering statistical transmutation of identical quantum particles
Simone Barbarino, Rosario Fazio, Vlatko Vedral +1
A fundamental pillar of quantum mechanics concerns indistinguishable quantum particles. In three dimensions they may be classified into fermions or bosons, having, respectively, an…
On the optimal working point in dissipative quantum annealing
Luca Arceci, Simone Barbarino, Davide Rossini +1
We study the effect of a thermal environment on the quantum annealing dynamics of a transverse-field Ising chain. The environment is modelled as a single Ohmic bath of quantum harm…
Topological phases in odd-legs frustrated synthetic ladders
S. Barbarino, M. Dalmonte, R. Fazio +1
The realization of the Hofstadter model in a strongly anisotropic ladder geometry has now become possible in one-dimensional optical lattices with a synthetic dimension. In this wo…
Dissipative Landau-Zener problem and thermally assisted Quantum Annealing
Luca Arceci, Simone Barbarino, Rosario Fazio +1
We revisit the issue of thermally assisted quantum annealing by a detailed study of the dissipative Landau-Zener problem in presence of a Caldeira-Leggett bath of harmonic oscillat…
Laughlin-like states in bosonic and fermionic atomic synthetic ladders
Marcello Calvanese Strinati, Eyal Cornfeld, Davide Rossini +5
The combination of interactions and static gauge fields plays a pivotal role in our understanding of strongly-correlated quantum matter. Cold atomic gases endowed with a synthetic…
Synthetic gauge fields in synthetic dimensions: Interactions and chiral edge modes
Simone Barbarino, Luca Taddia, Davide Rossini +2
Synthetic ladders realized with one-dimensional alkaline-earth(-like) fermionic gases and subject to a gauge field represent a promising environment for the investigation of quantu…
Crystallization of fractional charges in a strongly interacting quasi-helical quantum dot
F. Cavaliere, F. M. Gambetta, S. Barbarino +1
The ground-state electron density of a one-dimensional spin-orbit coupled quantum dot with a Zeeman term and strong electron interaction is studied at the fractional helical liquid…
Magnetic crystals and helical liquids in alkaline-earth fermionic gases
S. Barbarino, L. Taddia, D. Rossini +2
The joint action of a synthetic gauge potential and of atomic contact repulsion in a one-dimensional alkaline-earth(-like) fermionic gas with nuclear spin I leads to the existence…
Anomalous Friedel oscillations in a quasi-helical quantum dot
F. M. Gambetta, N. Traverso Ziani, S. Barbarino +2
The charge and spin patterns of a quantum dot embedded into a spin-orbit coupled quantum wire subject to a magnetic field are investigated. A Luttinger liquid theory is developed,…
Parity dependent Josephson current through a helical Luttinger liquid
Simone Barbarino, Rosario Fazio, Maura Sassetti +1
We consider a superconductor-two dimensional topological insulator- superconductor junction (S-2DTI-S) and study how the 2π- and 4π-periodic Josephson currents are affected by the…
Tunneling between helical edge states through extended contacts
G. Dolcetto, S. Barbarino, D. Ferraro +2
We consider a quantum spin Hall system in a two-terminal setup, with an extended tunneling contact connecting upper and lower edges. We analyze the effects of this geometry on the…
