Observation of Light-Induced Dipole-Dipole Forces in Ultracold Atomic Gases
Mira Maiwöger, Matthias Sonnleitner, Tiantian Zhang +7
We investigate an attractive force caused by light induced dipole-dipole interactions in freely expanding ultracold 87Rb atoms. This collective, light-triggered effect results in a…
A versatile quantum simulator for coupled oscillators using a 1D chain of atoms trapped near an optical nanofiber
Daniela Holzmann, Matthias Sonnleitner, Helmut Ritsch
The transversely confined propagating light modes of a nano-photonic optical waveguide or nanofiber can mediate effectively infinite-range forces. We show that for a linear chain o…
Synthesizing variable particle interaction potentials via spectrally shaped spatially coherent illumination
Daniela Holzmann, Matthias Sonnleitner, Helmut Ritsch
Collective scattering of spatially coherent radiation by separated point emitters induces inter-particle forces. For particles close to nano-photonic structures as, for example, na…
Mass-energy and anomalous friction in quantum optics
Matthias Sonnleitner, Stephen M. Barnett
The usual multipolar Hamiltonian for atom-light interaction features a non-relativistic moving atom interacting with electromagnetic fields which inherently follow Lorentzian symme…
Vacuum Friction
Stephen M. Barnett, Matthias Sonnleitner
We know that in empty space there is no preferred state of rest. This is true both in special relativity but also in Newtonian mechanics with its associated Galilean relativity. It…
Attractive force on atoms due to blackbody radiation
Philipp Haslinger, Matt Jaffe, Victoria Xu +5
Objects at finite temperature emit thermal radiation with an outward energy-momentum flow, which exerts an outward radiation pressure. At room temperature, a cesium atom scatters o…
The Roentgen interaction and forces on dipoles in time-modulated optical fields
Matthias Sonnleitner, Stephen M. Barnett
The Roentgen term is an often neglected contribution to the interaction between an atom and an electromagnetic field in the electric dipole approximation. In this work we discuss h…
Will a decaying atom feel a friction force?
Matthias Sonnleitner, Nils Trautmann, Stephen M. Barnett
We show how a simple calculation leads to the surprising result that an excited two-level atom moving through vacuum sees a tiny friction force of first order in v/c. At first sigh…
Self-ordering and collective dynamics of transversely illuminated point-scatterers in a 1D trap
Daniela Holzmann, Matthias Sonnleitner, Helmut Ritsch
We study point-like polarizable particles confined in a 1D very elongated trap within the evanescent field of an optical nano-fiber or nano-structure. When illuminated transversely…
Scattering approach to two-colour light forces and self-ordering of polarizable particles
Stefan Ostermann, Matthias Sonnleitner, Helmut Ritsch
Collective coherent scattering of laser light by an ensemble of polarizable point particles creates long range interactions, whose properties can be tailored by choice of injected…
Attractive Optical Forces from Blackbody Radiation
Matthias Sonnleitner, Monika Ritsch-Marte, Helmut Ritsch
Blackbody radiation around hot objects induces ac Stark shifts of the energy levels of nearby atoms and molecules. These shifts are roughly proportional to the fourth power of the…
Optomechanical deformation and strain in elastic dielectrics
Matthias Sonnleitner, Monika Ritsch-Marte, Helmut Ritsch
Light forces induced by scattering and absorption in elastic dielectrics lead to local density modulations and deformations. These perturbations in turn modify light propagation in…
