Quantum ground-state cooling of two librational modes of a nanorotor
Stephan Troyer, Florian Fechtel, Lorenz Hummer +4
Controlling the motion of nanoscale objects at the quantum limit promises new tests of quantum mechanics and advanced sensors. Rotational motion is of particular interest, as it fo…
Quantum Optical Binding of Nanoscale Particles
Henning Rudolph, UroÅ¡ DeliÄ, Klaus Hornberger +1
Optical binding refers to the light-induced interaction between two or more objects illuminated by laser fields. The high tunability of the strength, sign, and reciprocity of this…
Quantum theory of non-Hermitian optical binding between nanoparticles
Henning Rudolph, UroÅ¡ DeliÄ, 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…
Exponentially Enhanced non-Hermitian Cooling
Haowei Xu, UroÅ¡ DeliÄ, 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…
