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…
