Quantum Computing For Nuclear Physics, Aikaterini Nikou
Quantum Computing For Nuclear Physics, Aikaterini Nikou
2023 REYES Proceedings
Nuclear physics can greatly advance by taking advantage of quantum computing. Quantum computing can play a pivotal role in advancing nuclear physics and can allow for the description of physical situations and problems that are prohibitive to solve using classical computing due to their complexity. Some of the problems whose complexity requires using quantum computing to describe are: interacting quantum many-body and Quantum Field Theory problems such as simulating strongly interacting fields such as Quantum Chromodynamics with physical time evolution, the determination of the shape/phase of a nucleus using the time evolution of an appropriated observable as well as identifying …
Spontaneous Symmetry Breaking And Goldstone Theorem, Emilia Szymańska
Spontaneous Symmetry Breaking And Goldstone Theorem, Emilia Szymańska
2023 REYES Proceedings
We discuss the concept of spontaneous symmetry breaking and illustrate it with a general example. We consider Wigner-Weyl and Nambu-Goldstone realisations of symmetry in the quantum theory. Next, we state Goldstone’s theorem and sketch its proof. We discuss why quantum chromodynamics is not realised in the Wigner-Weyl mode. We also consider different order parameters of spontaneous chiral symmetry breaking.

Resonance Signatures In 𝜋+𝜋− Scattering: Theoretical Analysis And Interpretation, Mayul Verma
2023 REYES Proceedings
Hadron colour confinement, a phenomenon central to Quantum Chromodynamics (QCD), presents a formidable challenge in theoretical physics. The non-perturbative nature of confinement necessitates innovative approaches to the production of and reaction mechanisms between these subatomic particles. In the pursuit of comprehending the fundamental constituents of matter, particle resonances assume a pivotal role. Through the utilization of advanced methodologies like 𝑆-Matrix formulations, more profound insights into resonance phenomena and their effects on the dynamics of particle interactions can be attained. This research paper embarks on a mathematical journey that holds the potential to shed light on the intricate structure of particle …
