Observation of Chiral State Transfer Without Encircling an Exceptional Point
Hadiseh Nasari, Gisela Lopez-Galmiche, Helena E. Lopez-Aviles +7
The adiabatic theorem, a corollary of the Schrödinger equation, manifests itself in a profoundly different way in non-Hermitian arrangements, resulting in counterintuitive state tr…
Topological Modes in a Laser Cavity through Exceptional State Transfer
A. Schumer, Y. G. N. Liu, J. Leshin +8
Shaping the light emission characteristics of laser systems is of great importance in various areas of science and technology. In a typical lasing arrangement, the spatial profile…
Encircling exceptional points as a non-Hermitian extension of rapid adiabatic passage
Juraj Feilhauer, Alexander Schumer, Jörg Doppler +5
The efficient transfer of excitations between different levels of a quantum system is a task with many applications. Among the various protocols to carry out such a state transfer…
Non-Hermitian Ring Laser Gyroscopes with Enhanced Sagnac Sensitivity
Mohammad P. Hokmabadi, Alexander Schumer, Demetrios N. Christodoulides +1
Gyroscopes play a crucial role in many and diverse applications associated with navigation, positioning, and inertial sensing [1]. In general, most optical gyroscopes rely on the S…
