In the Color Glass Condensate framework, the collision of two high-energy nuclei, which are densely packed with gluons, produces a colored plasma consisting of overoccupied gluon fields, named the Glasma. The Glasma fields describe the very early stage of ultra-relativistic heavy-ion collisions, as done at the LHC. We describe this gluonic plasma by means of classical Yang-Mills field equations and we solve them numerically using a real-time formulation of lattice QCD. A special class of probes, namely jets and heavy quarks, are formed early and experience the Glasma fields. It is common to study their properties in an equilibrated plasma or a hydrodynamic medium, by completely neglecting the initial stage. In this talk, I will discuss our recent work about realistic simulations of hard probes in the pre-equilibrium stage. For this purpose, we developed an efficient numerical solver for the classical transport of dynamical quarks and gluons in a Glasma background field, using the colored particle-in-cell method. Our results reveal that the effect on the momentum broadening and transport coefficients for both jets and heavy quarks is extremely pronounced. This observation holds irrespective of the fine particle initialisation details, such as formation time, mass and momentum. Additionally, we extract two-particle correlations of diquark pairs, which also turn out to be highly impacted by the Glasma stage. This talk is based on Phys. Rev. D 107, 114021.

Dana Avramescu is currently a doctoral student at the University of Jyväskylä, part of the Center of Excellence in Quark Matter. Supervised by Tuomas Lappi and Heikki Mäntysaari, her work is about the transport of hard probes in the Glasma pre-equilibrium stage. Previously, she studied at the University of Bucharest, and her master thesis involved coupling the Glasma stage to viscous hydrodynamics. Recent notable achievements include flash talks at Quark Matter and Initial Stages.

Among quantum-inspired classical computing approaches to Quantum Simulation, Tensor Networks stand out as a promissing avenue to handle situation where the amount of entanglement is limited. 

This course provides an introduction to the use of Tensor Newtorks. The course will be in-person, and involve both theory presentations and python labs for practical use cases. There is a limited number of seats available. Registration is needed. Final admission will be subject to approval. The course is charge free. Finantial support is available for travelling upong request.

The pre-requisites involve knowledge and understanding of quantum mechanics of several constituents, like spin 1/2 systems, the meaning of Hamiltonian evolution, and the properties of mixed states and density matrices. At the computational level, python skills to write and debug codes made of several functions with numpy and scipy will do. 

The main speaker will be Luca Tagliacozzo, from Instituto de Física Fundamental, IFF-CSIC, who has significant contributions in the field as well as expertise in teaching this course. 

Contribution seminars form industry experts will be also programmed.

In one-dimensional scalar field theories a range of static solutions, representing kinks, sphalerons and kink-antikink chains, all obey a first-order field equation of the Bogomolny (BPS) type, and their energy is given by a Bogomolny-type formula. However, some are stable and some are not. We carefully distinguish the BPS kink solutions from the other, semi-BPS solutions, in terms of the zeros of the scalar field\'s potential.

I will present recent works on measurement protocols for two probes of many-body quantum chaos; (i) The spectral form factor (SFF) and (ii) Out of time ordered correlators (OTOC). SFF characterizes statistics of energy eigenvalues, making it a key diagnostic of many-body quantum chaos. In addition, partial spectral form factors (pSFFs) can be defined which refer to subsystems of the many-body system. They provide unique insights into energy eigenstate statistics of many-body systems. We propose a protocol that allows the measurement of the SFF and pSFFs in quantum many-body spin models, within the framework of randomized measurements. For OTOC we utilize properties of thermo field double states, which help to do measurements without reversing the time. In both cases, some experimental results will be shared.

 SUSY came about as a remarkable symmetry that combines spacetime and internal gauge symmetries under the same mathematical structure (supergroup). In its standard form, SUSY fermions and bosons are mirror images of each other. This unrealistic scenario requires some unspecified mechanism to violently break the SUSY. Perhaps, the 50 years of fruitless search for SUSY signals can be explained simply assuming that it is not a symmetry of nature. Apart from the thousands of authors, grants, experiments and PhD thesis that could have been wasted, it is a profoundly disappointing that there is no mechanism to combine spacetime and internal symmetries in a nontrivial way. In the unconventional approach reviewed here, the unwanted features of conventional SUSY are avoided, while the union of spacetime and internal symmetries is achieved. As a bonus gravity is inevitably included and new phenomena arise, which could help understanding nature a bit better.
