The structure of composite operators in gauge quantum field theories with matrix or tensor degrees of freedom is controlled by hidden symmetries which organise the combinatorics of gauge invariants. These include group algebras of symmetric groups and associated natural generalisations. Dualities in string theory, in particular gauge-string duality, motivate the formulation of new classical...
We argue that high energy heavy ion collisions at LHC offer the perfect setting to study the information theoretical aspects of thermalization and hadronization of gauge theories. After discussing results from numerical AdS calculations we focus on numerical Hamiltonian simulation of SU(2) on classical computers, as well as first steps to extend the application of AdS/CFT duality to the...
Lattice simulations using the Hamiltonian formulations are becoming increasingly important as they offer potential solutions to long-standing obstacles such as the sign problem. In particular, they are avenues to solving questions requiring real-time dynamics, string breaking, finite fermion densities, or highly curved space-time geometries amongst many others. Hamiltonian formulations of...
I will show that in the strong coupling expansion of large N QCD on a lattice, the dynamics of the confining string can be well approximated by a one dimensional spin chain. I will describe the prospects for simulations of this spin chain in various approximations and dimensions.
The real-time dynamics of gauge theories is one of the most promising applications for quantum devices where future quantum simulations are expected to provide a practical advantage over classical computers. However, it remains an outstanding challenge to reformulate non-abelian lattice gauge theories in a way that is tailored to quantum information processing.
In this talk, I will present a...
Gauge theories are a fundamental framework of modern physics and the staple of the Standard Model. Their principal property, gauge symmetry, implements the laws of nature through intrinsic local relations between matter and gauge fields, with Gauss’s law from electrodynamics as a paradigmatic example. In recent years, there has been a considerable drive in realizing gauge theories on quantum...
We explore the possibility of simulation of a well-known quantum-mechanical model of quantum gravity on a quantum computer. With the current limitations on the superconducting based hardware, we show that results for return probability and OTOC for small number of Majorana fermions are consistent with those obtained using exact classical methods after applying state-of-the-art error mitigation...
We develop a framework for the construction of the bulk theory dual to conformal field theory (CFT) without any assumption by means of a flow equation. Using the special flow equation, called the conformal flow, we show that the conformal transformation for a normalized smeared field exactly becomes a part of the general coordinate transformation, which would be the isometry of anti-de Sitter...
I will discuss how to put Jackiw-Teitelboim gravity with matter on quantum computer and protocols to explore physics related to wormholes. This talk is based on a work in progress with Rumi Hasegawa.
Quantum computers have the potential to expand the utility of lattice gauge theory to investigate non-perturbative particle physics phenomena that cannot be accessed using a standard Monte Carlo method due to the sign problem. Thanks to the qubit, quantum computers can store Hilbert space in a more efficient way compared to classical computers. This allows the Hamiltonian approach to be...
Advancements of detector sensitivity in the next generation of gravitational-wave observatories translate into several orders of magnitude larger detection rates and signals of hours of durations that start at a few Hz frequencies. Alongside the exciting sciences are the immediate challenges to prompt and accurate gravitational wave parameter estimation, a crucial part in gravitational-wave...
I would like to talk about the calculation methods for mass spectra of composite states
of gauge theories in the Hamiltonian formalism.
