General Information

This is the 12th of a series of annual international meetings that was initiated by Miloslav Znojil in 2003. The first two of these meetings were held in Prague (Czech Republic) in 2003 and 2004. These followed by larger gatherings in Istanbul (Turkey), Stellenbosch (South Africa), Bologna (Italy), London (UK), Benasque (Spain), Mumbai (India), Hangzhu (China), Dresden (Germany), and Paris (France). 

These meetings were initially attended by a small group of experts working on various aspects of pseudo-Hermitian and PT-symmetric Hamiltonians. Later they attracted the attention of a more diverse group of physicists and mathematicians interested in the study of non-Hermitian operators and their physical applications.

Since 2009 there has been a growing interest in the theoretical and experimental studies of the exceptional points associated with PT-symmetry breaking in PT-symmetric optical systems and the optical spectral singularities and their time-reversal dual that respectively yield threshold lasing and coherent perfect absorption of light. A more recent development, that has also attracted much attention, is an optical realization of the phenomenon of unidirectional invisibility and the study of its connection to  PT-symmetry. PHHQP12 intends to cover these and other more traditional topics of this series of workshops such as the mathematical and physical aspects of pseud-Hermitian and quasi-Hermitian (crypto-Hermitian) operators, indefinite-metric quantum theories, Krein-space methods, etc. A particular attention will be paid to the recent progress in the study of open quantum systems and resonances.
