Positivity Constraints for condensed matter and cosmology
/ Creminelli, Paolo (speaker)
The coefficients of the operators of an effective field theory (EFT) are constrained to satisfy certain inequalities, under the (mild) assumption that the UV completion satisfies general requirements of causality and unitarity. I discuss the extension of these ideas to theories where the Lorentz symmetry is spontaneously broken, as it happens in cosmology and condensed matter physics [...]

Dark side of ICT – AI in warfare and cyber-diplomacy
/ Siroli, Gian Piero (speaker) (Universita e INFN, Bologna (IT))
In the swiftly transforming realm of international security, the intersection of cyber-warfare, autonomous systems and artificial intelligence presents unprecedented challenges. Cyber-warfare has emerged as a strategic tool for both state and non-state actors, while information warfare can manipulate targets' perceptions, emotions, and behaviours.
The inherent vulnerabilities of AI, including the risk of adversarial attacks, add further complexity to this environment. [...]

Accessing the strong interaction in three-hadron systems with ALICE
/ Singh, Bhawani (speaker) (Technische Universitaet Muenchen (DE))
Understanding the structure of light nuclei and the interactions among their constituents has been a long-standing goal in nuclear physics. Nuclear systems composed of three hadrons, such as unbound ensembles formed by a deuteron and a third nucleon, serve as fundamental references in nuclear physics for constraining nuclear interactions and understanding the properties of nuclei [...]

An index for flux vacua
/ Lüst, Severin (speaker) (U. Montpellier)
One of the main challenges for string theory phenomenology is to reliably identify consistent four-dimensional vacua of string theory with low or broken supersymmetry. This task is difficult as one expects no such vacua in the asymptotic limits where one sends all coupling constants to zero or (equivalently) all moduli fields to infinity [...]

Large-scale Integrated Circuits with 2D MoS2 for Neuromorphic Computing
/ Kis, Andras (speaker) (EPFL)
Machine learning and signal processing on the edge are poised to influence our everyday lives with devices that will learn and infer from data generated by smart sensors and other devices for the Internet of Things. The next leap towards ubiquitous electronics requires increased energy-efficiency of processors for specialized data-driven applications. [...]

Handling photons in lattice QCD
/ Meyer, Harvey (speaker) (Johannes Gutenberg University Mainz)
I describe some of the computational challenges posed by handling photons in lattice QCD. In Euclidean space, amplitudes containing final-state photons are expressed in terms of hadronic correlation functions with a strong infrared weighting, which are hard to control. [...]

Holography and Regge Phases at Large U(1) Charge
/ Fardelli, Giulia (speaker) (Boston U.)
We use holography to study the spectrum of multi-twist operators, within conformal field theories in d>2, in the large spin limit. Focusing on a CFT with a global U(1) current, we explore its phase diagram as a function of the U(1) charge Q and angular momentum J, particularly at large J and Q. [...]

2D Gauge Theories on the Hamiltonian Lattice
/ Dempsey, Ross (speaker) (Princeton)
Lately there has been renewed interest in two-dimensional gauge theories, stemming from their applicability as toy models of QCD along with rapidly advancing techniques for simulating them both numerically and experimentally. I will start by discussing the U(1) theory coupled to a fermion in two dimensions, and important lessons from its ABJ anomaly that can be used to dramatically improve the accuracy of results obtained from the Hamiltonian lattice [...]
