Caustics are singularities arising from natural focusing and are well known in optics but also occur in any system that has waves including water and quantum waves. Caustics take on universal shapes that are described by catastrophe theory and dominate wave patterns. My group has been extending these ideas to quantum fields, such as those found in the sine-Gordon and Bose-Hubbard models. Our...
We numerically study the quantum dynamics of a bosonic Josephson junction (a Bose-Einstein condensate in a double-well potential) in the context of periodic driving of the tunnel coupling. In particular we examine how caustics, which can dominate the Fock space wavefunction following a sudden quench of the undriven system, are affected as the kicking strength is increased. In the limit of...
Quantum dots embedded within photonic nanowires can act as highly efficient single-photon generators. Integrating such sources on-chip offers enhanced stability and miniaturization; both of which are important in many applications involving quantum information processing. We employ a "pick and place" technique to transfer nanowires to on-chip waveguides where each nanowire contains a single...
