Dynamic Stabilization of a Quantum Many-Body Spin System

Dynamic stabilization of a quantum many-body spin system.

We demonstrate dynamic stabilization of a strongly interacting quantum spin system realized in a spin-1 atomic Bose-Einstein condensate. The spinor Bose-Einstein condensate is initialized to an unstable fixed point of the spin-nematic phase space, where subsequent free evolution gives rise to squeezing and quantum spin mixing. To stabilize the system, periodic microwave pulses are applied that ...

Coherent imaging spectroscopy of a quantum many-body spin system

Quantum simulation. Coherent imaging spectroscopy of a quantum many-body spin system.

Quantum simulators, in which well-controlled quantum systems are used to reproduce the dynamics of less understood ones, have the potential to explore physics inaccessible to modeling with classical computers. However, checking the results of such simulations also becomes classically intractable as system sizes increase. Here, we introduce and implement a coherent imaging spectroscopic techniqu...

Quantum Many Body System at Integer Coupling

The 1/r2 quantum many body problem, and the closely related Haldane-Shastry 1/r2 Heisenberg chain, are the subject of intense theoretical study at present, due in part to their relationship to an ideal gas obeying fractional statistics (see [1] for a review). One direction of study has been the exact calculation of some ground state correlation functions [1-5]. Let us briefly summarize the main...
