Spinsim: a GPU optimized python package for simulating spin-half and spin-one quantum systems
Alex Tritt, Joshua Morris, Joel Hochstetter +3
The Spinsim python package simulates spin-half and spin-one quantum mechanical systems following a time dependent Shroedinger equation. It makes use of numba.cuda, which is an LLVM…
Magic-wavelength Faraday probe measures spin continuously and without light shifts
M. Jasperse, M. J. Kewming, S. N. Fischer +3
We describe a dispersive Faraday optical probe of atomic spin which performs a weak measurement of spin projection of a quantum gas continuously for more than one second. To date f…
Measurement and extinction of vector light shifts using interferometry of spinor condensates
A. A. Wood, L. D. Turner, R. P. Anderson
We use differential Ramsey interferometry of ultracold atoms to characterize the vector light shift (VLS) from a far-off resonance optical dipole trap at . Th…
A Monte Carlo wavefunction method for semiclassical simulations of spin-position entanglement
C. J. Billington, C. J. Watkins, R. P. Anderson +1
We present a Monte Carlo wavefunction method for semiclassically modeling spin- systems in a magnetic field gradient in one dimension. Our model resolves the conflict of d…
Precise wavefunction engineering with magnetic resonance
P. B. Wigley, L. M. Starkey, S. S. Szigeti +4
Controlling quantum fluids at their fundamental length scale will yield superlative quantum simulators, precision sensors, and spintronic devices. This scale is typically below the…
Magnetic tensor gradiometry using Ramsey interferometry of spinor condensates
A. A. Wood, L. M. Bennie, A. Duong +3
We have realized a magnetic tensor gradiometer by interferometrically measuring the relative phase between two spatially separated Bose-Einstein condensates (BECs). We perform simu…
Precision atomic gravimeter based on Bragg diffraction
P. A. Altin, M. T. Johnsson, V. Negnevitsky +10
We present a precision gravimeter based on coherent Bragg diffraction of freely falling cold atoms. Traditionally, atomic gravimeters have used stimulated Raman transitions to sepa…
Relative intensity squeezing by four-wave mixing with loss: an analytic model and experimental diagnostic
M. Jasperse, L. D. Turner, R. E. Scholten
Four-wave mixing near resonance in an atomic vapor can produce relative intensity squeezed light suitable for precision measurements beyond the shot-noise limit. We develop an anal…
