📌IL NOBEL PER LA FISICA E LE FRONTIERE DELLA RICERCA QUANTISTICA A FIRENZE

I temi affrontati nell'attività di ricerca dai tre vincitori dell'edizione 2022 del riconoscimento sono strettamente collegati con l'attività e le sperimentazioni condotte al campus di Sesto fiorentino.
Alain Aspect è stato peraltro a lungo membro del Consiglio Direttivo del Laboratorio Europeo di Spettroscopia Non lineare.

E sulle nuove possibilità di elaborare l’informazione, messe a disposizione dalla fisica quantistica, gli scienziati di sono ancora più focalizzati con il

Palaiseau-Florence Workshop on Ultracold Atoms
Firenze, 19-21 April 2022

A three-day scientific workshop to discuss the most recent advancements in the context of ultracold atom physics and related fields. Experimental and theoretical groups from Palaiseau (France) and Florence (Italy) research areas will present their activities and discuss collaborations in topics ranging from metrology and entanglement to quantum transport and simulation.

The scientific program and all the information for attendance can be found on the workshop website

In their last paper published in Nature, the LiLab team unveils the long-sought elementary mechanism behind quantum vortex dymanics. Congratulations!

By controlling the generation and collision of individual vortices in atomic Fermi superfluids, a study provides a comprehensive view of vortex decay due to mutual friction and vortex–sound interaction.

Is there a better conductor than a superconductor? The neo-PhD Giulia Del Pace from LiLab answers to this question and talks about the new work of the Li group in the Magazine of the University of Florence.

Alla domanda risponde lo studio pubblicato su Physical Review Letters, che vede come prima autrice una neodottoressa di ricerca Unifi.

New study by the LiLab is published on Physical Review Letters!

🌊🌊🌊 In the work by Giulia Del Pace et al., we observe how charge neutrality boosts the tunneling transport of an ultracold fermionic liquid at unitarity compared to what happens in electronic superconductors.

The LENS QuantumGases group strongly supports the initiative of our colleagues of the Qombs Project and the United Nation campaign for the Elimination for Violence against Women.

Gender-based violence must stop now!!

It is a great privilege for us to welcome Nigel Cooper, Professor in Theoretical Physics of University of Cambridge. Prof. Cooper will honour us with his presence for one year as a Visiting Professor of the Department of Physics and Astronomy of the University of Florence.

The research interests of Prof. Cooper are focused on the nature and properties of the novel phases of matter that can emerge as a result of quantum mechanical effects in interacting many-particle systems. In particular, he is a world leader in the investigation of the role of topology in the collective properties of ultra-cold atomic gases and of the electronic properties of novel solid state materials. He was awarded the 2007 Maxwell Medal and Prize by the Institute of Physics, a Humboldt Research Award (2013), an EPSRC Established Career Fellowship (2013), a Simons Investigator Award (2017) and the 2019 Lord Rayleigh Prize of the IOP.

We are very grateful to him and looking forward to inspiring discussions and collaborations. We wish him a very pleasant and productive stay at University of Florence and LENS!

What causes a quasiparticle death?

A new study published in PRL in collaboration with Monash Uni Science and Ludwig-Maximilians-Universität München finds many-body dephasing to be the main culprit!

What causes quasiparticle death?

In large, interacting quantum systems, groups of particles can behave like a single particle, a 'quasiparticle'.

But those quasiparticles die young, lasting far, far less than a second. Why?

A new Monash Uni Science study published this week in PRL finds a culprit beyond the usual suspect (decay into lower energy states).

The new villain: many-body dephasing.

Understanding the properties of quasiparticles may be key to comprehending and controlling quantum effects like superconductivity and superfluidity.
