Squeezed Ground States in a Spin-1 Bose-Einstein Condensate
Lin Xin, Maryrose Barrios, Julia T. Cohen +1
We generate spin squeezed ground states in an atomic spin-1 Bose-Einstein condensate tuned nearthe quantum critical point between the polar and ferromagnetic quantum phases of the…
Fast generation of time-stationary spin-1 squeezed states by non-adiabatic control
Lin Xin, M. S. Chapman, T. A. B. Kennedy
A protocol for the creation of time-stationary squeezed states in a spin-1 Bose condensate is proposed. The method consists of a pair of controlled quenches of an external magnetic…
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…
Exploring Non-Abelian Geometric Phases in Spin-1 Ultracold Atoms
H. M. Bharath, Matthew Boguslawski, Maryrose Barrios +2
Non-Abelian and non-adiabatic variants of Berry's geometric phase have been pivotal in the recent advances in fault tolerant quantum computation gates, while Berry's phase itself i…
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…
