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, Uroš Delić, 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…
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…
Dry launching of silica nanoparticles in vacuum
Ayub Khodaee, Kahan Dare, Aisling Johnson +2
Clean loading of silica nanoparticles with a radius as small as ~50 nm is required for experiments in levitated optomechanics that operate in ultra-high vacuum. We present a cheap…
Dissipative phase transitions in optomechanical systems
Fatemeh Bibak, Uroš Delić, Markus Aspelmeyer +1
We show that optomechanical quantum systems can undergo dissipative phase transitions within the limit of small nonlinear interaction and strong external drive. In such a defined t…
Force-Gradient Sensing and Entanglement via Feedback Cooling of Interacting Nanoparticles
Henning Rudolph, Uroš Delić, Markus Aspelmeyer +2
We show theoretically that feedback-cooling of two levitated, interacting nanoparticles enables differential sensing of forces and the observation of stationary entanglement. The f…
Observation of strong and tunable light-induced dipole-dipole interactions between optically levitated nanoparticles
Jakob Rieser, Mario A. Ciampini, Henning Rudolph +5
Arrays of optically trapped nanoparticles have emerged as a promising platform for the study of complex non-equilibrium phenomena. Analogous to atomic many-body systems, one of the…
Detecting nonclassical correlations in levitated cavity optomechanics
