Probing the Degree of Coherence through the Full 1D to 3D crossover
Robert Shah, Thomas Barrett, Andrea Colcelli +3
We experimentally study a gas of quantum degenerate Rb atoms throughout the full dimensional crossover, from a one-dimensional (1D) system exhibiting phase fluctuations cons…
Free Fall of a Quantum Many-Body System
Andrea Colcelli, Giuseppe Mussardo, German Sierra +1
The quantum version of the free fall problem is a topic often skipped in undergraduate quantum mechanics courses because its discussion usually requires wavepackets built on the Ai…
Finite Temperature Off-Diagonal Long-Range Order for Interacting Bosons
Andrea Colcelli, Nicolò Defenu, Giuseppe Mussardo +1
Characterizing the scaling with the total particle number () of the largest eigenvalue of the one--body density matrix (), provides informations on the occurrence of the of…
Dynamics of one-dimensional quantum many-body systems in time-periodic linear potentials
Andrea Colcelli, Giuseppe Mussardo, German Sierra +1
We study a system of one-dimensional interacting quantum particles subjected to a time-periodic potential linear in space. After discussing the cases of driven one- and two-particl…
Integrable Floquet Hamiltonian for a Periodically Tilted 1D Gas
Andrea Colcelli, Giuseppe Mussardo, German Sierra +1
An integrable model subjected to a periodic driving gives rise generally to a non-integrable Floquet Hamiltonian. Here we show that the Floquet Hamiltonian of the integrable Lieb--…
Universal off-diagonal long-range order behaviour for a trapped Tonks-Girardeau gas
Andrea Colcelli, Jacopo Viti, Giuseppe Mussardo +1
The scaling of the largest eigenvalue of the one-body density matrix of a system with respect to its particle number defines an exponent and a coefficient $…
