Non-Hermitian dynamics and nonreciprocity of optically coupled nanoparticles
Manuel Reisenbauer, Henning Rudolph, Livia Egyed +5
Non-Hermitian dynamics, as observed in photonic, atomic, electrical, and optomechanical platforms, holds great potential for sensing applications and signal processing. Recently, f…
Exponentially Enhanced non-Hermitian Cooling
Haowei Xu, Uroš Delić, Guoqing Wang +3
Certain non-Hermitian systems exhibit the skin effect, whereby the wavefunctions become exponentially localized at one edge of the system. Such exponential amplification of wavefun…
Quantum theory of non-Hermitian optical binding between nanoparticles
Henning Rudolph, Uroš Delić, Klaus Hornberger +1
Recent experiments demonstrate highly tunable nonreciprocal coupling between levitated nanoparticles due to optical binding [Rieser et al., Science 377, 987 (2022)]. In view of rec…
