EVIDENCE FOR NEUTRINOLESS DOUBLE BETA DECAY
The data of the Heidelberg–Moscow double beta decay experiment for the measuring period August 1990–May 2000 (54.9813 kg y or 723.44 molyears), published recently, are analyzed using the potential ofExpand

Experimental observation of the topological structure of exceptional points.
We report on a microwave cavity experiment where exceptional points (EPs), which are square root singularities of the eigenvalues as function of a complex interaction parameter, are encircled in theExpand

PT symmetry and spontaneous symmetry breaking in a microwave billiard.
We demonstrate the presence of parity-time (PT) symmetry for the non-Hermitian two-state Hamiltonian of a dissipative microwave billiard in the vicinity of an exceptional point (EP). The shape of theExpand

The chirality of exceptional points
Abstract:Exceptional points are singularities of the spectrum and wave functions of a Hamiltonian which occur as functions of a complex interaction parameter. They are accessible in experiments withExpand

Exceptional points in a microwave billiard with time-reversal invariance violation.
We report on the experimental study of an exceptional point (EP) in a dissipative microwave billiard with induced time-reversal invariance (T) violation. The associated two-state Hamiltonian isExpand

Significance in gamma-ray astronomy - the Li & Ma problem in Bayesian statistics
The significance of having detected an astrophysical gamma ray source is usually calculated by means of a formula derived by Li & Ma (1983, ApJ, 272, 317). We solve the same problem in terms ofExpand

Induced violation of time-reversal invariance in the regime of weakly overlapping resonances.
We measure the complex scattering amplitudes of a flat microwave cavity (a "chaotic billiard"). Time-reversal (T) invariance is partially broken by a magnetized ferrite placed within the cavity. WeExpand

Chaotic scattering in the regime of weakly overlapping resonances.
We measure the transmission and reflection amplitudes of microwaves in a resonator coupled to two antennas at room temperature in the regime of weakly overlapping resonances and in a frequency rangeExpand
