N-Extended Lorentzian Kac-Moody algebras
Andreas Fring, Samuel Whittington
We investigate a class of Kac-Moody algebras previously not considered. We refer to them as n-extended Lorentzian Kac-Moody algebras defined by their Dynkin diagrams through the co…
Pseudo-Hermitian approach to Goldstone's theorem in non-Abelian non-Hermitian quantum field theories
Andreas Fring, Takanobu Taira
We generalise previous studies on the extension of Goldstone's theorem from Hermitian to non-Hermitian quantum field theories with Abelian symmetries to theories possessing a gloca…
Nonlocal gauge equivalence: Hirota versus extended continuous Heisenberg and Landau-Lifschitz equation
Julia Cen, Francisco Correa, Andreas Fring
We exploit the gauge equivalence between the Hirota equation and the extended continuous Heisenberg equation to investigate how nonlocality properties of one system are inherited b…
Goldstone bosons in different PT-regimes of non-Hermitian scalar quantum field theories
Andreas Fring, Takanobu Taira
We study the interplay between spontaneously breaking global continuous and discrete antilinear symmetries in a newly proposed general class of non-Hermitian quantum field theories…
Time-independent approximations for time-dependent optical potentials
Andreas Fring, Rebecca Tenney
We explore the possibility of modifying the Lewis-Riesenfeld method of invariants developed originally to find exact solutions for time-dependent quantum mechanical systems for the…
Eternal life of entropy in non-Hermitian quantum systems
Andreas Fring, Thomas Frith
We find a new effect for the behaviour of Von Neumann entropy. For this we derive the framework for describing Von Neumann entropy in non-Hermitian quantum systems and then apply i…
