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…
Electron spin control of optically levitated nanodiamonds in vacuum
Thai M. Hoang, Jonghoon Ahn, Jaehoon Bang +1
Electron spins of diamond nitrogen-vacancy (NV) centers are important quantum resources for nanoscale sensing and quantum information. Combining NV spins with levitated optomechani…
