XIX<vPHHQP<XX

Welcome to the website supporting the virtual seminar series on Pseudo-Hermitian Hamiltonians in Quantum Physics.

This virtual seminar series is part of the regular real life seminar series on Pseudo-Hermitian Hamiltonians in Quantum Physics that was initiated by Miloslav Znojil in 2003. It is intended to bridge the gap, caused by the COVID-19 pandemic, between the real life XIXth meeting and the upcoming XXth meeting in Santa Fe in 2021. For past events see the PHHQP website. The subject matter of this series is the study of physical aspects of non-Hermitian systems from a theoretical and experimental point of view. Of special interest are systems that possess a PT-symmetry (a simultaneous reflection in space and time).

PT and patterns in finite-density QCD

Abstract: A PT-symmetric extension of the Φ⁴- model exhibits patterned field configurations near its critical point. Analytic results and lattice simulations associate this patterning with tachyonic instabilities. Patterning is not confined, however, to just this two-component PT-symmetric scalar model with a Z(2) symmetry. Rather, patterned critical behavior occurs in broad universality classes of PT-symmetric theories with two or more components and any symmetry group. Finite-density QCD is a member of the PT-symmetric Z(2) universality class. This raises the possibility that stable patterns of confined and deconfined phase occur near the critical endpoint in the μ-T plane.
