Pneumatically actuated and kinematically positioned optical mounts compatible with laser-cooling experiments
R. C. Brown, S. Olmschenk, S. Wu +3
We present two complementary designs of pneumatically actuated and kinematically positioned optics mounts: one designed for vertical mounting and translation, the other designed fo…
Pump-Controlled Modal Interactions in Microdisk Lasers
Seng Fatt Liew, Li Ge, Brandon Redding +2
We demonstrate an effective control of nonlinear interactions of lasing modes in a semiconductor microdisk cavity by shaping the pump profile. A target mode is selected at the expe…
Optimization of collisional Feshbach cooling of an ultracold nondegenerate gas
Marlon Nuske, Eite Tiesinga, L. Mathey
We optimize a collision-induced cooling process for ultracold atoms in the nondegenerate regime. It makes use of a Feshbach resonance, instead of rf radiation in evaporative coolin…
Few-body physics of ultracold atoms and molecules with long-range interactions
Yujun Wang, P. S. Julienne, Chris H. Greene
The quantum mechanical few-body problem at ultracold energies poses severe challenges to theoretical techniques, particularly when long-range interactions are present that decay on…
Topological defect lasers
Sebastian Knitter, Seng Fatt Liew, Wen Xiong +3
We demonstrate topological defect lasers in a GaAs membrane with embedded InAs quantum dots. By introducing a disclination to a square-lattice of elliptical air holes, we obtain sp…
Tunable Spin-Orbit Coupling via Strong Driving in Ultracold Atom Systems
K. Jiménez-García, L. J. LeBlanc, R. A. Williams +5
Spin-orbit coupling (SOC) is an essential ingredient in topological materials, conventional and quantum-gas based alike.~Engineered spin-orbit coupling in ultracold atom systems --…
A Michelson-Morley Test of Lorentz Symmetry for Electrons
T. Pruttivarasin, M. Ramm, S. G. Porsev +4
All evidence so far suggests that the absolute spatial orientation of an experiment never affects its outcome. This is reflected in the Standard Model of physics by requiring all p…
Systematic evaluation of an atomic clock at 2e-18 total uncertainty
T. L. Nicholson, S. L. Campbell, R. B. Hutson +9
The pursuit of better atomic clocks has advanced many research areas, providing better quantum state control, new insights in quantum science, tighter limits on fundamental constan…
Improving the gate fidelity of capacitively coupled spin qubits
Xin Wang, Edwin Barnes, S. Das Sarma
Capacitively coupled semiconductor spin qubits hold promise as the building blocks of a scalable quantum computing architecture with long-range coupling between distant qubits. How…
Inhomogeneous broadening of optical transitions of 87Rb atoms in an optical nanofiber trap
J. Lee, J. A. Grover, J. E. Hoffman +2
We experimentally demonstrate optical trapping of 87Rb atoms using a two-color evanescent field around an optical nanofiber. In our trapping geometry, a blue-detuned traveling wave…
Entanglement entropy of dispersive media from thermodynamic entropy in one higher dimension
Mohammad F. Maghrebi, Homer Reid
A dispersive medium becomes entangled with zero-point fluctuations in the vacuum. We consider an arbitrary array of material bodies weakly interacting with a quantum field and comp…
Cold atomic and molecular collisions: approaching the universal loss regime
Matthew D. Frye, Paul S. Julienne, Jeremy M. Hutson
We investigate the behaviour of single-channel theoretical models of cold and ultracold collisions that take account of inelastic and reactive processes using a single parameter to…
Reactive collisions in confined geometries
Zbigniew Idziaszek, Krzysztof Jachymski, Paul S. Julienne
We consider low energy threshold reactive collisions of particles interacting via a van der Waals potential at long range in the presence of external confinement and give analytic…
A LEGO Watt Balance: An apparatus to determine a mass based on the new SI
L. S. Chao, S. Schlamminger, D. B. Newell +6
A global effort to redefine our International System of Units (SI) is underway and the change to the new system is expected to occur in 2018. Within the newly redefined SI, the pre…
Charged skyrmions on the surface of a topological insulator
Hilary M. Hurst, Dmitry K. Efimkin, Jiadong Zang +1
We consider the interplay between magnetic skyrmions in an insulating thin film and the Dirac surface states of a 3D topological insulator (TI), coupled by proximity effect. The ma…
2D Superexchange mediated magnetization dynamics in an optical lattice
R. C. Brown, R. Wyllie, S. B. Koller +3
The competition of magnetic exchange interactions and tunneling underlies many complex quantum phenomena observed in real materials. We study non-equilibrium magnetization dynamics…
Metastable Bose-Einstein Condensation in a Strongly Correlated Optical Lattice
David McKay, Ushnish Ray, Stefan Natu +3
We experimentally and theoretically study the peak fraction of a Bose-Einstein condensate loaded into a cubic optical lattice as the lattice potential depth and entropy per particl…
Fractional Quantum Hall States of Rydberg Polaritons
Mohammad F. Maghrebi, Norman Y. Yao, Mohammad Hafezi +3
We propose a scheme for realizing fractional quantum Hall states of light. In our scheme, photons of two polarizations are coupled to different atomic Rydberg states to form two fl…
Ancillary qubit spectroscopy of cavity (circuit) QED vacua
Jared Lolli, Alexandre Baksic, David Nagy +2
We investigate theoretically how the spectroscopy of an ancillary qubit can probe cavity (circuit) QED ground states containing photons. We consider three classes of systems (Dicke…
