Encircling an Exceptional Point
C. Dembowski, B. Dietz, H. -D. Graef +4
We calculate analytically the geometric phases that the eigenvectors of a parametric dissipative two-state system described by a complex symmetric Hamiltonian pick up when an excep…

Comment on ''Exceptional points and double poles of the S matrix''
C. Dembowski, B. Dietz, H. -D. Graef +4
In a recent paper [Phys. Rev. E 67, 026204 (2003)], Rotter calculates the geometric phases that are picked up by the eigenvectors of a two-state quantum system when an exceptional…

Observation of a Chiral State in a Microwave Cavity
C. Dembowski, B. Dietz, H. -D. Graef +4
A microwave experiment has been realized to measure the phase difference of the oscillating electric field at two points inside the cavity. The technique has been applied to a diss…
