XXIII Training Course in the Physics of Strongly Correlated Systems

The on-line Course is organized by the International Institute for Advanced Scientific Studies "E.R. Caianiello" (IIASS), http://www.iiassvietri.it/in collaboration with the Department of Physics, University of Salerno (https://www.df.unisa.it/) from the 4th to the 9th of October 2021.

The Training Course is aimed at graduate students and PostDoc researchers, and offers the fascinating possibility to meet selected experts belonging to different areas in Condensed Matter Physics and Optical Physics.

This year the focus will be on:
Trends and Platforms for Quantum Technologies

The Second Quantum Revolution is unfolding now, exploiting the enormous advancements in our ability to detect and manipulate single quantum objects and triggering the development of the different Quantum Technologies on different platforms ranging from solid state platforms to atomic, molecular and optical platforms. New perspectives and opportunities are opening for researchers in this field. The training course Platforms for Quantum Technologies issued to PhD and postdoc students in Physics is intended to give an introduction to the different platforms for quantum technologies from different perspectives from the fabrication, to the modelization and numerical implementation of quantum circuits (Josephson junctions qubits etc) and cold atoms platforms for Quantum Technologies. Some basics of quantum communication processes and introduction to quantum information theory will also be given.

The Training Course is not intended as a series of formal lectures where no real contact develops between lecturers and audience. The idea is to let meet virtually senior and young researchers in a close and informal atmosphere.
The course lasts one week and sees the participation of five senior lecturers. In the morning, each senior researcher will deliver a lecture. The afternoon sessions are devoted to training and emphasis will be on introducing young researchers to some specific problems and guiding them through their solution. The participants will be encouraged to present their own activity. The aim is to help young researchers to become more familiar with different approaches and start new collaborations. A limited number of participants will have the opportunity to deliver a seminar.

The Course is open to a limited number of young (aged under 40) researchers. The registration fee is €150.00 and includes all the didactics material, lectures slides and school proceedings.

In the 2021 edition, young researchers will benefit from training in scientific techniques and various methodologies under the guidance of highly qualified senior lecturers:

Prof. Ramon Aguado, Spanish National Research Council (CSIC), Madrid, Spain

Prof. Maciej Lewenstein, ICFO, Institute for Photonic Science, Barcellona, Spain

Prof. Michael Stern, Bar Ilan University, Ramat Gan, Israel

Prof. Francesco Tafuri, Department of Physics, University of Naples, Italy

Prof. Felix von Oppen, Department of Physics, Freie Universität Berlin, Berlin, Germany

     A topic seminar will be held by Prof. Emanuele Dalla Torre, Bar-Ilan University and Righetti  Computing.

 


The Director of the Course: Prof. Ferdinando Mancini

The Coordinator of the Course: Prof. Roberta Citro

In continuation with the Atomtronics@Benasque meetings, the goal of Atomtronics@TIIAbuDhabi2021  is to follow up recent achievements in cold atoms quantum technology with a particular focus on atomtronics. Applicative, experimental and theoretical aspects of matter-wave  circuits   will be covered, both to extend the scope of the existing atom-based quantum simulators and devices and to project platforms for new routes in quantum technology.
 
Due to the covid outbreak, the meeting will take place online, coordinated by the Quantum Research Centre, Technology Innovation Institute, AbuDhabi, with a collaboration of the COST action AtomQT.
 
The talks will be scheduled May 31st-June 4th  and June 7th-11th, 4:30-7:30pm GST, 8:30-11:30pm SGT, 7-9am MST, 2:30-5:30pm CET. 
 
Because of the  constraints imposed by the online format, we cannot accept  contributing talks. 
We encourage the  interested  participants to apply for a poster breakout room.

InDark

Inflation, Dark Matter and the Large-Scale Structure of the Universe

 

 

Abstract


 
InDark focuses on investigating crucial aspects of the standard cosmological model and its extensions, and their connection with particle physics. This includes models of inflation in the early Universe, the nature of dark matter and dark energy, the properties of neutrinos and other light relics, and the viability of modified gravity models
 
In the past two decades, we have witnessed tremendous progress in cosmology, thanks to the wealth of data that have become available from experiments like Planck, that released its legacy data in 2018, the many multi-wavelength surveys that mapped the large-scale structure of the Universe to unprecedented precision, like SDSS-BOSS, and a number of probes of cosmic expansion, such as that provided by SN-Ia. This has allowed sharpening our understanding of the Universe. Even though most of the data can be interpreted in terms of the concordance Lambda-Cold Dark Matter (ΛCDM) model, recently some tensions between different observations have surfaced that might point to the necessity of revising the model. Moreover, even if phenomenologically very successful, the ΛCDM is somehow unsatisfying from the point of view of fundamental physics, as the very nature of dark energy and dark matter, as well as the details of the early phase of inflationary expansion, are still unknown. Indeed, these two open issues – observational tensions and theoretical understanding of the model – might well be related.  Coming years will bring an ever-increasing amount of new data, from the next generation of cosmic microwave background (CMB) polarization experiments, aiming at the detection of B-modes, both primordial and lensing-generated (e.g. Simons Observatory, LiteBIRD, CMB-S4), to the galaxy and galaxy cluster surveys from the next large-scale structure (LSS) probes (e.g. Euclid, DESI, SKA, WFIRST, LSST). Gravitational waves (GW) observatories like the operating VIRGO and LIGO, and in the future LISA and the Einstein Telescope, are sensitive to early Universe signals and can act as laboratories to test fundamental physics, other than being able to constrain the expansion history of the Universe through the observations of standard sirens. This wealth of data will have to be interpreted in light of models.
Within InDark, we interpret the combined information from present and future observations of CMB radiation, LSS, GW signals, and other cosmological probes in light of models, while also sharpening the theoretical tools that allow such an interpretation. To this purpose, we employ a wide range of techniques, including theoretical modelling of the cosmological evolution (using both analytical and numerical methods), analysis and interpretation of available data, simulations of mock data samples from future experiments. Our goal is to advance in the path that goes from a simple phenomenological description of the Universe and of its evolution, to fully understanding the nature of its constituents, the behaviour of gravity on cosmological scales and the mechanisms generating the primordial cosmological perturbations. At the same time, this strategy allows to constrain models of particle physics. Once paired with reliable theoretical predictions, present and forthcoming data provide a treasure trove that allows to test with increasing accuracy, and possibly rule out, various models of the Universe, its evolution and the structures within.
