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.

In this paper we holographically study the strongly coupled dynamics of the field theory on I-branes (D5 branes intersecting on a line). In this regime, the field theory becomes (2 + 1) dimensional with 16 supercharges. The dual background has an IR singularity. We resolve this singularity by compactifying the theory on a circle, preserving 4 supercharges. We study various aspects: confinement, symmetry breaking, Entanglement Entropy, etc. We also discuss a black membrane solution and make some comments on the string sigma-model on our backgrounds.

No serán do venres 29 de setembro, ducias de persoas vinculadas a 10 centros de investigación galegos amosarán á cidadanía o traballo que desenvolven co gallo da G-Night, a Noite Galega das Persoas Investigadoras. Este evento, que celebra en 2023 a súa undécima edición, achegará a ciencia a rúas, museos, institucións educativas e bares. Baixo o lema ‘Conciencias creativas’, as actividades salientarán a creatividade e a súa relación co coñecemento científico como eixo da G-Night.

Observando os raios cósmicos

O IGFAE participará na actividade que será o epicentro da G-Night en Santiago de Compostela: os obradoiros e demostracións programados no Claustro do Colexio de Fonseca das 18 ás 21 horas do venres 29. Persoal do centro amosará ao público o abraiante do mundo dos raios cósmicos: partículas que chegan dende o espazo e bombardean a Terra dende todas as direccións.

Para observar estas partículas utilizaranse dous tipos de detectores. Un deles é o Minipix, desenvolvido polo CERN e utilizado no Proxecto MEDRA, unha iniciativa do IGFAE dirixida ao alumnado de institutos de Galicia. Con estes detectores é posible observar en tempo real as pegadas destes raios cósmicos, identificar que tipo de partículas se están a ver e cales son as súas características.

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.
