Non-Hermitian formalism and nonlinear physics
Hichem Eleuch, Ingrid Rotter
The non-Hermitian formalism is used at present in many papers for the description of open quantum systems. A special language developed in this field of physics which makes it diff…
Equilibrium states in open quantum systems
Ingrid Rotter
The aim of the paper is to study the question whether or not equilibrium states exist in open quantum systems that are embedded in at least two environments and are described by a…
Non-Hermitian Quantum Physics of Open Systems
Ingrid Rotter
Information on quantum systems can be obtained only when they are open (or opened) in relation to a certain environment. As a matter of fact, realistic open quantum systems appear…
Critical points in two-channel quantum systems
Hichem Eleuch, Ingrid Rotter
Calculations for open quantum systems are performed usually by taking into account their embedding into one common environment, which is mostly the common continuum of scattering w…
Gain and loss in open quantum systems
Hichem Eleuch, Ingrid Rotter
Photosynthesis is the basic process used by plants to convert light energy in reaction centers into chemical energy. The high efficiency of this process is not yet understood today…
Resonances in open quantum systems
Hichem Eleuch, Ingrid Rotter
The Hamilton operator of an open quantum system is non-Hermitian. Its eigenvalues are, generally, complex and provide not only the energies but also the lifetimes of the states of…
