Self-ordering and cavity cooling using a train of ultrashort pulses
Valentin Torggler, Ivor Krešić, Ticijana Ban +1
A thin atomic gas in an optical resonator exhibits a phase transition from a homogeneous density to crystalline order when laser illuminated orthogonal to the resonator axis. We st…
Ion-based nondestructive sensor for cavity photon numbers
Moonjoo Lee, Konstantin Friebe, Dario A. Fioretto +7
We dispersively couple a single trapped ion to an optical cavity to extract information about the cavity photon-number distribution in a nondestructive way. The photon-number-depen…
A Quantum N-Queens Solver
Valentin Torggler, Philipp Aumann, Helmut Ritsch +1
The N-queens problem is to find the position of N queens on an N by N chess board such that no queens attack each other. The excluded diagonals N-queens problem is a variation wher…
Quenches across the self-organization transition in multimode cavities
Tim Keller, Valentin Torggler, Simon B. Jäger +3
A cold dilute atomic gas in an optical resonator can be radiatively cooled by coherent scattering processes when the driving laser frequency is tuned close but below the cavity res…
Quantum annealing with ultracold atoms in a multimode optical resonator
Valentin Torggler, Sebastian Krämer, Helmut Ritsch
A dilutely filled -site optical lattice near zero temperature within a high- multimode cavity can be mapped to a spin ensemble with tailorable interactions at all length scal…
Optimized multifrequency light collection by adaptive self-ordering of scatterers in optical resonators
Valentin Torggler, Helmut Ritsch
Mobile light scatterers in a high-Q optical cavity transversely illuminated by laser light close to a cavity resonance form ordered patterns, which maximize light scattering into t…
