Cat states and multipartite entanglement, on arXiv

Tue, 10 May 2022 00:00:00 +0000

The many-body dynamics of certain quantum simulators generates a cascade of peculiar entangled states, including spin-squeezed and Schroedinger-cat states. We report on this in our most recent preprint “Multipartite entangled states in dipolar quantum simulators”, now available on arXiv.

Adiabatic spin squeezing, on arXiv

Fri, 18 Feb 2022 00:00:00 +0000

Here’s one more way to generate scalable spin squeezing with quantum simulators, when they implement a model featuring spontaneous symmetry breaking. In our new work, with colleagues from Lyon and Villetaneuse, we show that adding a small magnetic field is all you need to do - see also here.

Simple theorems on spin squeezing, on arxiv

Tue, 15 Jun 2021 00:00:00 +0000

Our study of spin squeezing continues, and we uploaded a new work on arxiv (link) where we prove that it captures the first form of correlations appearing in non-equilibrium or adiabatic dynamics.

New on arxiv: Spin squeezing and Anderson tower

Mon, 15 Mar 2021 00:00:00 +0000

Together with colleagues from ENS Lyon, we just uploaded our new work on arxiv (link), dealing with the generation of spin squeezing in the dynamics of some long-range quantum spin models.

Today I gave the talk “A scheme to detect anyons in cold atoms” at the condensed-matter working group of ENS-Lyon. Here are the slides I presented.

VaQuM2020 School

Fri, 20 Dec 2019 00:00:00 +0000

Here is an announcement for the school VaQuM 2020 - Variational Methods for Quantum Many-Body Systems, featuring six mini-courses on variational approaches to the quantum many-body problem. The school will take place at Ecole Normale Supérieure de Lyon in spring 2020 (from March 30th to April 1st), and the deadline for applying is on February 16th. Detailed information are available on the school website.

New on arxiv: Harper-Hofstadter model via Tree Tensor Networks

Tue, 15 Oct 2019 00:00:00 +0000

Our work on the quasihole excitations of the Harper-Hofstadter model is now on arxiv (link), see here for more details. For this study we made use of the Tree Tensor Network Ansatz.

New paper on arxiv (repulsive Fermi polaron in two dimensions)

Mon, 27 May 2019 00:00:00 +0000

We uploaded our work about polarons in two-dimensional Fermi gases on arxiv (link), see here for more details. The data obtained through Quantum Monte Carlo simulations are also available (link). This work is the result of the collaboration of groups in Trento, Barcelona and Milano.
