Kibble-Zurek Mechanism in a Spin-1 Bose-Einstein Condensate
M. Anquez, B. A. Robbins, H. M. Bharath +3
We observe power-law scaling of the temporal onset of excitations with quench speed in the neighborhood of the quantum phase transition between the polar and broken-axisymmetry pha…

Characterizing the energy gap and demonstrating an adiabatic quench in an interacting spin system
T. M. Hoang, M. Anquez, M. J. Boguslawski +3
Spontaneous symmetry breaking occurs in a physical system whenever the ground state does not share the symmetry of the underlying theory, e.g., the Hamiltonian. It gives rise to ma…

Parametric Excitation and Squeezing in a Many-Body Spin System
T. M. Hoang, M. Anquez, B. A. Robbins +4
We demonstrate a new method to coherently excite and control the quantum spin states of an atomic Bose gas using parametric excitation of the collective spin by time varying the re…
