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…
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…
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…
Theory of nanoparticle cooling by elliptic coherent scattering
Henning Rudolph, Jonas Schäfer, Benjamin A. Stickler +1
Coherent scattering of an elliptically polarised tweezer into a cavity mode provides a promising platform for cooling levitated nanoparticles into their combined rotational and tra…
Cooling nanorotors by elliptic coherent scattering
Jonas Schäfer, Henning Rudolph, Klaus Hornberger +1
Simultaneously cooling the rotational and translational motion of nanoscale dielectrics into the quantum regime is an open task of great importance for sensing applications and qua…
Entangling levitated nanoparticles by coherent scattering
Henning Rudolph, Klaus Hornberger, Benjamin A. Stickler
We show how entanglement between two optically levitated nanoparticles can be generated and detected by coherent scattering of tweezer photons into a single cavity mode. Triggered…
