Zeeman-insensitive cooling of a single atom to its two-dimensional motional ground state in tightly focused optical tweezers
Pimonpan Sompet, Yin H. Fung, Eyal Schwartz +3
We combine near--deterministic preparation of a single atom with Raman sideband cooling, to create a push button mechanism to prepare a single atom in the motional ground state of…
Different growth rates for spin and superfluid order in a quenched spinor condensate
Andréane Bourges, P. B. Blakie
In this paper we study the coarsening dynamics of a spinor condensate quenched into an easy-axis ferromagnetic phase by a sudden change in the quadratic Zeeman energy. We show that…
Large net-normal dispersion Er-doped fibre laser mode-locked with a nonlinear amplifying loop mirror
Patrick Bowen, Miro Erkintalo, Neil G. R. Broderick
We report on an environmentally stable, all-PM-fibre, Er-doped, mode-locked laser with a central wavelength of 1550 nm. Significantly, the laser possesses large net-normal dispersi…
Effects of dopant type and concentration on the femtosecond laser ablation threshold and incubation behaviour of silicon
Reece N. Oosterbeek, Carsten Corazza, Simon Ashforth +1
In laser micromachining, the ablation threshold (minimum fluence required to cause ablation) is a key performance parameter and overall indicator of the efficiency of material remo…
Solving the spin-2 Gross-Pitaevskii equation using exact nonlinear dynamics and symplectic composition
L. M. Symes, P. B. Blakie
We develop numerical methods for solving the spin-2 Gross-Pitaevskii equation. The basis of our work is a two-way splitting of this evolution equation that leads to two exactly sol…
Mode-locked Yb-doped fiber laser emitting broadband pulses at ultra-low repetition rates
Patrick Bowen, Miro Erkintalo, Richard Provo +2
We report on an environmentally stable, Yb-doped, all-normal dispersion, mode-locked fibre laser that is capable of creating broadband pulses with ultra-low repetition rates. Speci…
Dynamics of polar-core spin vortices in a ferromagnetic spin-1 Bose-Einstein condensate
Lewis A. Williamson, P. B. Blakie
A ferromagnetic spin-1 condensate supports polar-core spin vortices (PCVs) in the easy-plane phase. We derive a model for the dynamics of these PCVs using a variational Lagrangian…
Resonant transfer of large momenta from finite duration pulse sequences
Julia Fekete, Shijie Chai, Simon A. Gardiner +1
We experimentally investigate the atom optics kicked particle at quantum resonance using finite duration kicks. Even though the underlying process is quantum interference it can be…
Hidden long-range order in a spin-orbit coupled two-dimensional Bose gas
Shih-Wei Su, I-Kang Liu, Shih-Chuan Gou +3
A spin-orbit coupled two-dimensional (2D) Bose gas is shown to simultaneously possess quasi and true long-range order in the total and relative phase sectors, respectively. The tot…
Exactly solvable model for a solitonic vortex in a compressible superfluid
L. A. Toikka, J. Brand
Vortex motion is a complex problem due to the interplay between the short-range physics at the vortex core level and the long-range hydrodynamical effects. Here we show that the hy…
Polarization-selective out-coupling of whispering gallery modes
Florian Sedlmeir, Matthew R. Foreman, Ulrich Vogl +6
Whispering gallery mode (WGM) resonators are an important building block for linear, nonlinear and quantum optical experiments. In such experiments, independent control of coupling…
Experimental observation of coherent cavity soliton frequency combs in silica microspheres
Karen E. Webb, Miro Erkintalo, Stéphane Coen +1
We report on the experimental observation of coherent cavity soliton frequency combs in silica microspheres. Specifically, we demonstrate that careful alignment of the microsphere…
Magnetic lattices for ultracold atoms and degenerate quantum gases
Yibo Wang, Prince Surendran, Smitha Jose +6
We review recent developments in the use of magnetic lattices as a complementary tool to optical lattices for trapping periodic arrays of ultracold atoms and degenerate quantum gas…
Mode Modification of Plasmonic Gap Resonances induced by Strong Coupling with Molecular Excitons
Xingxing Chen, Yu-Hui Chen, Jian Qin +4
Plasmonic cavities can be used to control the atom-photon coupling process at the nanoscale, since they provide ultrahigh density of optical states in an exceptionally small mode v…
An all-optical buffer based on temporal cavity solitons operating at 10 Gb/s
Jae K. Jang, Miro Erkintalo, Jochen Schröder +3
We demonstrate the operation of an all-optical buffer based on temporal cavity solitons stored in a nonlinear passive fiber ring resonator. Unwanted acoustic interactions between n…
Dielectric tuning and coupling of whispering gallery modes using an anisotropic prism
Matthew R. Foreman, Florian Sedlmeir, Harald G. L. Schwefel +1
Optical whispering gallery mode (WGM) resonators are a powerful and versatile tool used in many branches of science. Fine tuning of the central frequency and line width of individu…
Multiple scattering dynamics of fermions at an isolated p-wave resonance
Ryan Thomas, Kris O. Roberts, Eite Tiesinga +4
The wavefunction for indistinguishable fermions is anti-symmetric under particle exchange, which directly leads to the Pauli exclusion principle, and hence underlies the structure…
Refractory period of an excitable semiconductor laser with optical injection
Bruno Garbin, Axel Dolcemascolo, Franco Prati +3
Injection-locked semiconductor lasers can be brought to a neuron-like excitable regime when parameters are set close to the unlocking transition. Here we study experimentally the r…
Second-harmonic assisted four-wave mixing in chip-based microresonator frequency comb generation
Xiaoxiao Xue, François Leo, Yi Xuan +6
Simultaneous Kerr comb formation and second-harmonic generation with on-chip microresonators can greatly facilitate comb self-referencing for optical clocks and frequency metrology…
The universe on a table top: engineering quantum decay of a relativistic scalar field from a metastable vacuum
Oleksandr Fialko, Bogdan Opanchuk, Andrei I. Sidorov +2
The quantum decay of a relativistic scalar field from a metastable state ("false vacuum decay") is a fundamental idea in quantum field theory and cosmology. This occurs via local f…
