Monopole Antimonopole Instability in Non-Hermitian Coupled Waveguides
Rosie Hayward, Fabio Biancalana
A non-Hermitian coupled waveguide system with periodically varying parameters, in which the Berry curvature is analogous to a hyperbolic magnetic monopole or antimonopole, is inves…

Complex Berry phase instability in PT-symmetric coupled waveguides
Rosie Hayward, Fabio Biancalana
We show that the analogue of the geometric phase for non-Hermitian coupled waveguides with PT-symmetry and at least one periodically varying parameter can be purely imaginary, and…

Direct measurements of the extraordinary optical momentum and transverse spin-dependent force using a nano-cantilever
M. Antognozzi, C. R. Bermingham, R. L. Harniman +8
Known since Kepler's observation that a comet's tail is oriented away from the sun, radiation pressure stimulated remarkable discoveries in electromagnetism, quantum physics and re…
