Hamiltonian Formulations of Lattice Gauge Theories, with an eye towards Quantum Simulation* / Grabowska, Dorota (speaker) (CERN)
There are many fundamental questions in particle and nuclear physics that cannot be addressed via classical computing techniques. These include the equation of state for finite density nuclear matter, real-time dynamics of quantum field theories from first-principles and non-perturbative aspects of chiral gauge theories. [...]

Bootstrapping the a-anomaly in 4d QFTs* / Karateev, Denis (speaker) (University of Geneva)
I will discuss 4d scattering amplitudes in UV complete quantum field theories (QFTs). I will show how the a-anomaly describing its UV fixed point is related to parameters describing the scattering amplitude via unitarity. [...]

Hydrodynamization, asymptotics and the early to late time interpolation in relativistic hydrodynamics* / Aniceto, Inês (speaker) (University of Southampton)
Dissipative relativistic hydrodynamics is expected to describe the late times, thermalised behaviour of strongly coupled fluids such as a strongly coupled super Yang-Mills plasma. These systems are then accurately described by a hydrodynamic series expansion in small gradients. [...]

Aspects of Numerical Bootstrap* / Xin, Yuan (speaker) (Yale University)
My talk consists of two parts. In the first part, I will discuss a conformal bootstrap study of three dimensional Quantum Electrodynamics coupled to four flavors of electrons. [...]

Bootstrapping photon scattering in 3+1d* / Hebbar, Aditya (speaker) (École Polytechnique)
The S-matrix bootstrap is a program where one uses the general principles of analyticity, crossing symmetry and unitarity of scattering amplitudes to study the allowed space of quantum field theories. In this talk I will consider the two photon to two photon scattering amplitude and explain how we can use numerical S-matrix bootstrap methods to derive non-perturbative bounds on Wilson coefficients in the low energy effective field theory expansion of photons..

Confinement versus 1-form symmetries at large N* / Cherman, Aleksey (speaker) (University of Minnesota)
There are two known ways to tie quark confinement to symmetries: one way (the older one) in terms of "center symmetry", and the other one (the newer one) is in terms of a "1-form symmetry". By now it is widely accepted that the new idea of 1-form symmetry, which is based on the existence of co-dimension-2 topological operators, is a generalization of the old idea of center symmetry. [...]

Hamiltonian truncation for real time dynamics in (gauge) QFT* / Kukuljan, Ivan (speaker) (Max Planck Institute for Quantum Optics)
Hamiltonian truncation methods represent a powerful toolbox for a set of problems that are otherwise very challenging in strongly coupled quantum field theory: nonequilibrium physics and real time evolution. In many such cases analytical approaches are limited as well as numerical tools like lattice gauge theory and tensor networks. [...]

Tensor Networks: entanglement and the simulation of quantum many-body problems / Bañuls, Mari Carmen (speaker) (Max Planck Institute for Quantum Optics)
*Theory Colloquium* The term Tensor Network States (TNS) designates a number of ansatzes that can efficiently represent certain states of quantum many-body systems. In particular, ground states and thermal equilibrium of local Hamiltonians, and, to some extent, real time evolution can be numerically studied with TNS methods. [...]

Adiabatic continuity, TQFT couplings, and calculable confinement / Ünsal, Mithat (speaker) (North Carolina State University)
I will describe the idea of adiabatic continuity which can be used to continuously connect strongly coupled gauge theories on R^4 to compactified gauge theories on two set-ups: R^3 x S^1 and R^2 x T^2. Recall that in standard (thermal) compactifications, there are generically phase transitions. [...]

Conformal Colliders Meet the LHC* / Moult, Ian (speaker) (Yale University)
Jets of hadrons produced at high-energy colliders provide experimental access to the dynamics of asymptotically free quarks and gluons and their confinement into hadrons. Motivated by recent developments in conformal field theory, we show that questions of interest in collider physics can be reformulated as the study of correlation functions of a specific class of light-ray operators and their associated operator product expansion (OPE). [...]
