Experimental and theoretical characterisation of Stokes polarimetry of the potassium D1 line with neon buffer gas broadening
Sharaa A. Alqarni, Danielle Pizzey, Steven A. Wrathmall +1
This study presents a comprehensive experimental and theoretical characterisation of Stokes polarimetry in potassium (K) vapour on the D1 line. Measurements were performed in the w…
Light propagation through an atomic vapor with non-orthogonal electric field modes
Jack D. Briscoe, Danielle Pizzey, Robert M. Potvliege +2
Alkali-metal atomic vapors are the foundation of an ever-growing range of applications, driven by a comprehensive understanding of their interaction with light. In particular, many…
Self-induced transparency and optical transients in atomic vapors
B. S. Cartwright, S. A. Wrathmall, R. M. Potvliege
The rapid turn-on of a strong, resonant, continuous wave laser field may trigger the formation of a transient oscillation akin to a train of damped solitons, before the vapor-field…
The Role of Buffer Gas in Shaping the D1 Line Spectrum of Potassium Vapour
Sharaa A. Alqarni, Danielle Pizzey, Steven A Wrathmall +1
In this study, we investigate the effect of buffer gas and magnetic field on the spectral line shapes of the potassium D1 transition using sealed vapour cells filled with varying a…
Modelling spectra of hot alkali vapour in the saturation regime
Daniel R Häupl, Clare R Higgins, Danielle Pizzey +5
Laser spectroscopy of hot atomic vapours has been studied extensively. Theoretical models that predict the absolute value of the electric susceptibility are crucial for optimising…
Solving physics-based initial value problems with unsupervised machine learning
Jack Griffiths, Steven A. Wrathmall, Simon A. Gardiner
Initial value problems -- a system of ordinary differential equations and corresponding initial conditions -- can be used to describe many physical phenomena including those arise…
Indirect measurement of atomic magneto-optical rotation via Hilbert transform
Jack D Briscoe, Danielle Pizzey, Steven A Wrathmall +1
The Kramers-Kronig relations are a pivotal foundation of linear optics and atomic physics, embedding a physical connection between the real and imaginary components of any causal r…
Exploiting non-orthogonal eigenmodes in a non-Hermitian optical system to realize sub-100 MHz magneto-optical filters
Fraser D. Logue, Jack. D. Briscoe, Danielle Pizzey +2
Non-Hermitian physics is responsible for many of the counter-intuitive effects observed in optics research opening up new possibilities in sensing, polarization control and measure…
Voigt transmission windows in optically thick atomic vapours: a method to create single-peaked line centre filters
Jack D Briscoe, Fraser D Logue, Danielle Pizzey +2
Cascading light through two thermal vapour cells has been shown to improve the performance of atomic filters that aim to maximise peak transmission over a minimised bandpass window…
Better magneto-optical filters with cascaded vapor cells in the Faraday-Faraday and Faraday-Voigt geometries
Fraser D. Logue, Jack D. Briscoe, Danielle Pizzey +2
Single-cell magneto-optical Faraday filters find great utility and are realized with either 'wing' or 'line center' spectral profiles. We show that cascading a second cell with ind…
Quasi-simultons in thermal atomic vapors
Thomas P. Ogden, K. A. Whittaker, J. Keaveney +3
The propagation of two-color laser fields through optically thick atomic ensembles is studied. We demonstrate how the interaction between these two fields spawns the formation of c…
Optimized ultra-narrow atomic bandpass filters via magneto-optic rotation in an unconstrained geometry
James Keaveney, Steven A. Wrathmall, Charles S. Adams +1
Atomic bandpass filters are widely used in a variety of applications, owing to their high peak transmission and narrow bandwidth. Much of the previous literature has used the Farad…
Variational determination of approximate bright matter-wave soliton solutions in anisotropic traps
T. P. Billam, S. A. Wrathmall, S. A. Gardiner
We consider the ground state of an attractively-interacting atomic Bose-Einstein condensate in a prolate, cylindrically symmetric harmonic trap. If a true quasi-one-dimensional lim…
A quantum-mechanical study of rotational transitions in H2 induced by H
S A Wrathmall, D R Flower
Cross sections have been computed for rotational transitions of H2, induced by collisions with H atoms, using a recent H - H2 potential calculated by Mielke et al. [1]. These resul…
