Spontaneous CPT violation and quantum anomalies in a model for matter–antimatter asymmetry in the cosmos

NE Mavromatos, S Sarkar - Universe, 2018 - mdpi.com
We review scenarios of baryogenesis through leptogenesis at early epochs of the universe,
in string-inspired minimal extensions of the Standard Model (SM), involving heavy right …

Gauge symmetries and the Higgs mechanism in Quantum Finance

I Arraut - Europhysics Letters, 2023 - iopscience.iop.org
By using the Hamiltonian formulation, we demonstrate that the Merton-Garman equation
emerges naturally from the Black-Scholes equation after imposing invariance (symmetry) …

The probability flow in the Stock market and Spontaneous symmetry breaking in Quantum Finance

I Arraut, JA Lobo Marques, S Gomes - Mathematics, 2021 - mdpi.com
The spontaneous symmetry breaking phenomena applied to Quantum Finance considers
that the martingale state in the stock market corresponds to a ground (vacuum) state if we …

Hawking radiation as a manifestation of spontaneous symmetry breaking

I Arraut - Symmetry, 2024 - mdpi.com
We demonstrate that black hole evaporation can be modeled as a process where one
symmetry of the system is spontaneously broken continuously. We then identify three free …

Revenue Management in Airlines and External Factors Affecting Decisions: The Harmonic Oscillator Model

I Arraut, W Rosado, V Leong - Mathematics, 2024 - mdpi.com
The Revenue Management (RM) problem in airlines for a fixed capacity, single resource

Herglotz's variational problem for non-conservative system with delayed arguments under Lagrangian framework and its Noether's theorem

Y Zhang - Symmetry, 2020 - mdpi.com
Because Herglotz's variational problem achieves the variational representation of non-
conservative dynamic processes, its research has attracted wide attention. The aim of this …

Topological quantum statistical mechanics and topological quantum field theories

Z Zhang - Symmetry, 2022 - mdpi.com
The Ising model describes a many-body interacting spin (or particle) system, which can be
utilized to imitate the fundamental forces of nature. Although it is the simplest many-body …

Symmetry breaking in interacting ring-shaped superflows of Bose–Einstein condensates

A Oliinyk, I Yatsuta, B Malomed, A Yakimenko - Symmetry, 2019 - mdpi.com
We demonstrate that the evolution of superflows in interacting persistent currents of ultracold
gases is strongly affected by symmetry breaking of the quantum vortex dynamics. We study …

Symmetries for nonconservative field theories on time scale

O Postavaru, A Toma - Symmetry, 2021 - mdpi.com
