Recent years have seen significant progress in the understanding of deformations of integrable string sigma models, their relation to non-abelian and Poisson-Lie duality, and their possible AdS/CFT interpretation in terms of non-commutative field theory. Moreover, these models can also be naturally recast in terms of double and exceptional field theory. As such, numerous interesting new connections between these different research areas are developing, promising to shed light on various important open questions.

The goal of this workshop is to bring together experts from the fields of

• Deformations of integrable models
• Worldsheet dualities and extended field theories
• Non-commutative and non-associative QFT
• Quantum integrable systems in gauge/gravity duality

to facilitate exchange of ideas, collaboration, and the development of new insights across these fields.

Driven by new constraints from the LHC proton Clead program, global analyses of nuclear parton distribution functions (nPDFs) are going through a phase of rapid development, attracting also new groups to join the field. Giving first a brief introduction to the global analysis approach of nPDFs, I then discuss the current status of the field and in particular what we do and do not have well under control in terms of different parton flavours. In the latter part of the talk I will concentrate on the new precision constraints on the nuclear gluons, namely the nuclear modification ratios of dijet and D-meson cross sections in proton Clead versus proton Cproton collisions at 5.02 TeV.

Ultralight bosonic fields can form long-lived condensates around astrophysical black holes by virtue of the superradiant instability. This classical phenomenon has potentially observable consequences that allows us to infer properties of beyond-standard model particles using observations of black holes. So far, most studies have been restricted to the fastest growing superradiant mode with important conclusions, e.g., regarding the phase-space of black holes and potential constraints on the ultralight fields.

Systems in nature, however, are more complex and I will discuss the evolution of bosonic clouds whose angular distribution is described by a more complicated superposition of multipoles as may be expected for example after a black hole merger. I will further discuss observational implications in the scenario

In recent years, topological effects have found a variety of remarkable applications in quantum physics. A conceptual insight as to why topology plays a role in quantum physics is presented. This review includes basic explanations of how topology is a solution for quantum information and computation. New forms of quantum matter have appeared in condensed matter such as topological insulators and superconductors. They will be described in a broad context and emphasis is given on the classification of topological orders as new forms of quantum entanglement, highlighting their similarities and differences. A glimpse into the possible future developments will be commented in the outlook.

A II Feira de Innovación da USC, dirixida a alumando de secundaria e bacharelato, celebrarase na Cidade da Cultura, os días 27 e 28 de novembro. O público participante poderá coñecer de primeira man ao longo destas dúas xornadas, a diversa oferta docente, de investigación e de servizos que ofrece a Universidade. Esta iniciativa contará cun espazo de atención ao estudantado para a resolución de dúbidas e ampliación de información relacionada coas titulacións da USC e a súa ampla oferta de servizos. Exhibicións e demostracións de carácter interactivo para achegar aos visitantes exemplos dos proxectos de investigación nos que a USC está a traballar serán outros dos elementos que nutrirán o programa desta feira. A exposición de contidos vencellados a proxectos de Aprendizaxe-Servizo e a difusión das accións de voluntariado que a USC ten en marcha; así como unha mostra do inventario do Servizo de Publicacións da USC, completarán o programa. De xeito paralelo ás seccións permanentes, a feira contará con relatorios divulgativos, a cargo do persoal docente e investigador da USC, que permitirán por o foco nas súas diferentes liñas de investigación. O investigador do IGFAE Néstor Armesto impartirá o primeiro de eles, titulado ““Dos fundamentos ás aplicacións: para que sirve a Física de Partículas?”.

Quantum Computation has emerged as a new paradigm to solve certain problems that are beyond reach for conventional programming. Although still at its dawn, possible fields of application have been identified and tackled with promising results.

If confirmed, the recent announcement of the achievement of Quantum Supremacy will boost the activity in this field to limits not yet to be foreseen.

This workshop focusses on the relations between Quantum Computation (QC) and High Performance Computing (HPC) and the synergies that may appear between them for use in the scientific and technical fields. Ongoing initiatives of implementation will be presented by active researcher centres and companies. Also upcoming developments will be accounted for, mainly connected with Quantum Machine Learning strategies.

With the commissioning of the upgraded LHC collider, High Energy Physics (HEP) at CERN will face a shortage of computing resources by a factor between 10 and 100. Quantum Computing (QC) has the potential to offer unprecedented performances, but at the price of a fundamental rethinking of our algorithms and computing models. This talk will first introduce the principles of Quantum Computing. It will then present some possible avenues to exploit QC for HEP research, with emphasis on the projects currently under way or in preparation at CERN in connection with HEP physicists and the major technology providers. In particular we will expand on the areas where we see the greatest potential for “Quantum Dominance” and we will consider what could be the impact of QC on the HEP computing model. We will also point out what are the possible uses outside the realm of HEP of the proposed techniques and applications.

One of the main findings of the experimental program on ultrarelativistic heavy ion collisions is that the produced medium appears to have a very small shear viscosity to entropy ratio. After an introduction to the subject I will review the challenges in the theory description, focussing in particular on the effective kinetic theory approach, which allows to compute both the transport coefficients, such as the shear viscosity, and the medium modifications to jets, another striking finding of the experimental program. After introducing the main features of the kinetic framework, which requires the assumption of weak coupling, I will review the recent results in extending such approach to next-to-leading order, so that one can estimate the uncertainties that arise when extrapolating to realistic couplings.

El IGFAE, instituto de la Red de Centros Singulares de Investigación de la Universidad de Santiago, celebra una jornada de divulgación conjunta con el CiQUS, CiMUS y CiTIUS para acercar a la ciudadanía gallega la labor de excelencia de sus investigaciones. Charlas, experimentos y talleres infantiles completan el programa de esta actividad gratuita que requiere inscripción previa en www.cienciasingular.usc.es.
