Nonlocal current-response theory of structured-light dichroism
Akihito Kato, Nobuhiko Yokoshi
We develop a nonlocal minimal-coupling theory of structured-light dichroism. Optical absorption is written as a bilinear functional of the incident vector potential and the nonloca…

Kelvin-Wave-Inspired Optical Vortex Excitation in Kerr Nonlinear Media
Yosuke Minowa, Nobuhiko Yokoshi, Makoto Tsubota
We demonstrate a direct one-to-one correspondence between nonlinear optical fields in defocusing Kerr media and wave functions in weakly interacting Bose-Einstein condensates or qu…
