Quantum simulation of string breaking dynamics
By Federica Surace Keywords: Variational quantum simulation, Hubbard Model, Rydberg atom array, string breaking
In Quantum Chromodynamics we can observe string breaking. If we have a quark and an antiquark close to each other, the flux tube connecting the tube as an associated Energy , where is the string tension and is the distance between the 2 Particles. It is possible to increase the distance ( maybe with something else I missed. Help me ❓ ) such that the flux tube is broken into 2 different ones, with the creation of a quark/antiquark particle pair created as a way to break the flux tube.
The above can be modelled through the Ising Model, with defining equation . In this setup we can observe constrainement ( What is this? Help me ❓ ), and we are hoping to see string breaking.
Enhancing parameter estimation for the non-linear Schrodinger Equation using Möbius transformations
By Reinhardt David Keywords: [[Gross–Pitaevskii equation]
Towards prime factorisation in holographic traps
We want to build a potential that has the first primes as the energy levels. is built using a “chain” of Hamiltonians, using the supersymmetric quantum mechanics method. It is unclear what the method is. Help me ❓
See Holographic Realization of the Prime Number Quantum Potential
Idea by Renzo Testa: split the factorisation potential to have different primes present in each axis, to remove degeneracies in the factorisation.

The goal is to build complex circuits to do quantum calculations and quantum sensing through the use of Ring potentials. We generate currents though ??, phase imprinting, the transfer of angular momentum of light or by rotating the trap potential. This gives us a quantised calculation, where we have a persistent current.
