=============

We are pleased to announce the MaX school:


Ab initio many-body perturbation theory: from equilibrium to time-resolved 
spectroscopies and nonlinear optics

The school will take place in person, from May 22nd to May 26th, 2023 at 
Argiletum palace in Rome.

The aim of this school is to equip students with the essential knowledge, 
practical skills and computational tools needed to tackle today’s novel 
and challenging problems in materials science and nonequilibrium physics. 
We will introduce students to many-body perturbation theory (MBPT) 
approaches, including advanced concepts, for modelling nonequilibrium 
phenomena from first principles.  We will also discuss how model systems 
can help overcome some of the limitations of fully ab initio schemes.

The school features theoretical and technical lectures in the morning, 
followed by hands-on in the afternoon. Distinguished scientists and 
emerging young researchers in the field of condensed matter and 
nonequilibrium physics will provide the theoretical background and 
technical lectures. Each topic will be introduced with a general overview 
of experimental measurements and/or physical problems, with emphasis on 
the connection to the simulations performed by the students in the 
hands-on sessions, which will be led by the main developers of the codes 
Yambo [1] and CHEERS [2].


The main topics covered include the GW approximation for quasiparticle 
corrections and the Bethe-Salpeter Equation (BSE) for excitons, with a 
focus on  recent developments ìn the Yambo code. Furthermore, we will 
introduce the specific usage of the code in massively parallel 
environments equipped with modern accelerated video cards (GPUs).
Then, students will be introduced to nonequilibrium Green's function 
theory (NEGF), with theoretical  lectures covering modern pump-and-probe 
experiments based on ultra-short laser pulses as well as nonlinear optical 
properties.  Recent developments in the Yambo code to capture the physics 
of nonequilibrium quasiparticles, excitonic energies and the simulation of 
time-resolved ARPES spectroscopy will be discussed. Finally, students will 
be guided through the main concepts needed to treat  dynamical 
self-energies within NEGF in order to address dissipative mechanisms and 
carrier (exciton) dynamics, with hands-on on the usage of the linear 
scaling implementation available in the CHEERS code [2].

Applicants  are required to have a background in DFT and in running DFT 
simulations.

There is no registration fee and we encourage applications from female 
scientists. Participants will have the opportunity to present a poster and 
discuss their results in a dedicated session.

Yambo is a flagship code of the MaX Centre of Excellence and of the 
recently established  ICSC PNRR Italian National Centre for HPC, Big Data 
and Quantum Computing.

CHEERS is a simulation tool for correlated hole-electron evolution from 
real-time simulations developed at the University of Rome Tor Vergata.
