An electric dipole moving in a magnetic field acquires a geometric phase known as the He-McKellar-Wilkens (HMW) phase, which is the electromagnetic dual of the Aharanov-Casher phase. The HMW phase was first measured in 2012 using an atom interferometer [1]. In that experiment the electric and magnetic fields were static. We propose a modification where these fields are generated by laser...
We compare the results of Electromagnetically Induced Transparency (EIT) and Four-Wave Mixing (4WM) in both thermal Rubidium vapor and cold atom-based systems. Our aim is to balance simplicity and fidelity in systems that aim to produce atom-resonant quantum stated of light. We discuss the construction of a Magneto Optical Trap (MOT) on an extremely low budget and discuss strategies for...
We consider a dilute gas of bosons in a slowly rotating toroidal trap, focusing on the two-mode regime consisting of a non-rotating mode and a rotating mode corresponding to a single vortex. This system undergoes a symmetry breaking transition as the ratio of interactions to `disorder potential’ is varied and chooses one of the two modes spontaneously, an example of macroscopic quantum...
Coherent anti-Stokes Raman scattering (CARS) is a nonlinear optical process that is used for spectroscopy and imaging. The stimulated CARS signal is orders of magnitude stronger than in spontaneous Raman scattering, enabling CARS to achieve substantially faster acquisition speeds. This has positioned CARS as a desirable alternative to spontaneous Raman scattering as a contrast mechanism for...
The Abraham-Minkowski controversy refers to the ambiguity in defining the momentum of light within a dielectric medium. The choice one has in the partitioning of the total stress energy tensor of a system into a “material” portion and an “electromagnetic” portion has historically led to vigorous debate. The difference between Abraham’s formulation of the momentum density of light in a medium...
