Quasiadiabatic dynamics of ultracold bosonic atoms in a one-dimensional optical superlattice

A. Dhar, D. Rossini, B. P. Das

We study the quasiadiabatic dynamics of a one-dimensional system of ultracold bosonic atoms loaded in an optical superlattice. Focusing on a slow linear variation in time of the su…

Density Matrix Renormalization Group for Dummies

G. De Chiara, M. Rizzi, D. Rossini +1

We describe the Density Matrix Renormalization Group algorithms for time dependent and time independent Hamiltonians. This paper is a brief but comprehensive introduction to the su…

Quantum correlations and limit cycles in the driven-dissipative Heisenberg lattice

E. T. Owen, J. Jin, D. Rossini +2

Driven-dissipative quantum many-body systems have attracted increasing interest in recent years as they lead to novel classes of quantum many-body phenomena. In particular, mean-fi…

Discrete time crystal in a finite chain of Rydberg atoms without disorder

Chuhui Fan, D. Rossini, Han-Xiao Zhang +3

We study the collective dynamics of a clean Floquet system of cold atoms, numerically simulating two realistic set-ups based on a regular chain of interacting Rydberg atoms driven…

Photon transfer in ultrastrongly coupled three-cavity arrays

S. Felicetti, G. Romero, D. Rossini +2

We study the photon transfer along a linear array of three coupled cavities where the central one contains an interacting two-level system in the strong and ultrastrong coupling re…

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…

Quantum parameter estimation affected by unitary disturbance

A. De Pasquale, D. Rossini, P. Facchi +1

We provide a general framework for handling the effects of a unitary disturbance on the estimation of the amplitude associated to a unitary dynamics. By computing an analytica…

Quantum phases of spinful Fermi gases in optical cavities

E. Colella, R. Citro, M. Barsanti +2

We explore the quantum phases emerging from the interplay between spin and motional degrees of freedom of a one-dimensional quantum fluid of spinful fermionic atoms, effectively in…

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…
