In this talk, I explore the concept of compositeness in relation to QFT and argue that there is no satisfactory, exact definition of compositeness. Therefore, we are forced to conclude that all bound states, from pions to people, have the same fundamentality and that the sentence "chairs are made of ...

I will review recent progress on the connections between scattering amplitudes in quantum field theory and the geometry of Amplituhedron, a recently discovered mathematical object which captures particle dynamics of strong interactions. In this picture, the physics problem of predicting the outcomes of particle scattering is reformulated as the mathematical ...

Self-gravitating systems -- such as star clusters, stellar discs, and dark matter halos -- are rich with dynamical phenomena. They exhibit both resonant (long-range) and non-resonant (short-range) dynamics, with unclear transition regimes. The coupling of linear response theory, kinetic theory, quasilinear theory, and N-body approaches for studying self-gravitating systems is now within ...

'Dark matter' (DM) is a dynamical hypothesis born from our inability to comprehend kinematic observations at the galaxy scale and larger using baryonic matter only. Astronomers have struggled with the implications of DM for galaxy formation and evolution for decades. Conversely, we've exploited observations and cosmological simulations to constrain ...

Lattice Field Theories are a mature tool that yields robust predictions for precision tests of the Standard Model and potential BSM candidates. Larger volumes, finer lattice spacings and decorrelated configurations are some of the requirements to tame the systematic errors still affecting the current simulations. Improved algorithms, and strong mathematical ...

This event will be mainly sponsored by the Royal Society of Chemistry Statistical Mechanics and Thermodynamics group. The group is interested in a range of problems, covering the properties of molecules and the behaviour of macroscopic matter and is an interdisciplinary enterprise, embracing synthetic chemistry, physical chemistry, physics, polymer science ...

Dry and wet layers on a wall are the surface manifestation of equilibrium liquid-vapour phase transitions. Active liquids are disordered nonequilibrium systems that dissipate energy locally, able to produce phase separation in the absence of attractive interactions. We connect the emergent motility-induced separation of model active liquids with effective many-body ...

Soft materials and complex fluids are a fundamental component of modern industry and everyday life. The majority of the materials around us are made by chemical or physical crosslinking of linear polymers. However, a growing number of groups are exploring an entirely new class of materials with unique properties governed ...

The 8th edition of the Higgs Centre School of Theoretical Physics will take place from 22-26 May 2023. The scientific programme starts at 9:00 on Monday 22nd, and ends at 17:30 on Friday 26th. This year's edition of the HC School focuses on aspects of radiative corrections ...

Next Generation Quantum Theory of Atoms in Molecules (NG-QTAIM) is constructed from the eigenvectors of the Hessian of the total (real-space) charge density distribution ρ(r) field and can also use the eigenvectors of the stress tensor σ(r) and the Ehrenfest Force F(r) = -∙σ(r). NG-QTAIM can, for ...

RADCOR 2023 – 16th International Symposium on Radiative Corrections: Applications of Quantum Field Theory to Phenomenology, Sunday 28th May - Friday 2nd June, Crieff, Scotland. This conference is the 16th in the series of biennial RADCOR conferences on radiative corrections. It is devoted to the applications of quantum field theory to particle ...

The purpose of the workshop is to discuss recent developments in QCD+QED calculations, with particular emphasis on converging on prescriptions to define isospin-breaking corrections to hadronic observables. The main goal is to discuss with lattice practitioners and phenomenologists for a potential future update of the FLAG review. There will ...

If we take an elastic rubber wire, for instance of the type used in earphone sets, and keep twisting up one portion, at some point it buckles and writhes in 3D. Old telephone cords do exactly the same, and tend to end up into a tangled mess after months of ...

Physics by the Lake is the UK national summer school on theoretical condensed matter physics, aimed at PhD students towards the end of their first year. While geared towards UK students, we welcome participants worldwide. It is organised by the Institute of Physics (IOP) Theory of Condensed Matter group. It ...
