Staircase in magnetization and entanglement entropy of spin squeezed condensates
H. M. Bharath, M. S. Chapman, C. A. R. Sá de Melo
Staircases in response functions are associated with physically observable quantities that respond discretely to continuous tuning of a control parameter. A well-known example is t…
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…
