Comment on "Amplified emission and lasing in photonic time crystals"
Jagang Park, Hee Chul Park, Kyungmin Lee +5
Lyubarov et al. (Research Articles, 22 July 2022, p. 425) claim that the spontaneous emission rate of an atom vanishes at the momentum gap edges of photonic Floquet media. We show…
Bloch theorem dictated wave chaos in microcavity crystals
Chang-Hwan Yi, Hee Chul Park, Moon Jip Park
Universality class of wave chaos emerges in many areas of science, such as molecular dynamics, optics, and network theory. In this work, we generalize the wave chaos theory to cavi…
Pumping and cooling of nanomechanical vibrations generated by Cooper pair exchange
A. V. Parafilo, L. Y. Gorelik, H. C. Park +1
We consider a nanoelectromechanical system composed of a carbon nanotube suspended between two normal leads and coupled to a superconducting scanning tunneling microscope (STM) tip…
Revealing non-Hermitian band structures of photonic Floquet media
Jagang Park, Hyukjoon Cho, Seojoo Lee +7
Periodically driven systems, characterised by their inherent non-equilibrium dynamics, are ubiquitously found in both classical and quantum regimes. In the field of photonics, thes…
