Giant Non-reciprocity Near Exceptional Point Degeneracies
Roney Thomas, Huanan Li, F. M. Ellis +1
We show that gyrotropic structures with balanced gain and loss that respect anti-linear symmetries exhibit a giant non-reciprocity at the so-called exact phase where the eigenfrequ…

Bypassing the bandwidth theorem with PT symmetry
Hamidreza Ramezani, J. Schindler, F. M. Ellis +2
The beat time τ_{fpt} associated with the energy transfer between two coupled oscillators is dictated by the bandwidth theorem which sets a lower bound τ_{fpt}\sim 1/δω. We show, b…
