Random-matrix theory of amplifying and absorbing resonators with PT or PTT' symmetry
Christopher Birchall, Henning Schomerus
We formulate gaussian and circular random-matrix models representing a coupled system consisting of an absorbing and an amplifying resonator, which are mutually related by a genera…

Fractal Weyl laws for amplified states in PT-symmetric resonators
Christopher Birchall, Henning Schomerus
We find that in nonhermitian PT-symmetric systems (as realized in resonators with balanced absorption and amplification), a mechanism based on quantum-to-classical correspondence r…

Counting statistics for mesoscopic conductors with internal degrees of freedom
Christopher Birchall, Henning Schomerus
We consider the transport of electrons passing through a mesoscopic device possessing internal dynamical quantum degrees of freedom. The mutual interaction between the system and t…
