Measuring electric quadrupole moments - the shapes of atomic nuclei

New methods to determine the shapes of atomic nuclei via the measurement of their electric quadrupole moment are being developed. Most nuclei are prolate spheroids - shaped like an Australian Rules football. As well as giving a picture of the nucleus, the quadrupole moment is an important observable to test theory.

Interactions between antimatter and ultracold atoms

Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science.

Miniature absolute gravimeter for long-term gravity surveys

Absolute gravimeters tie their measurement of gravity to the definition of the second

leveraging modern vacuum, laser, and micro-electromechanical systems.

Optical quantum memory

An optical quantum memory will capture a pulse of light, store it and then controllably release it. This has to be done without ever knowing what you have stored, because a measurement will collapse the quantum state. We are exploring a "photon echo" process to achieve this goal.

Stochastic dynamics of interacting systems and integrability

There are many interesting physical statistical systems which never reach thermal equilibrium. Examples include surface growth, diffusion processes or traffic flow. In the absence of general theory of such systems a study of particular models plays a very important role. Integrable systems provide examples of such systems where one can analyze time dynamics using analytic methods.

Variational approach to many-body problems

In recent years there was a large boost in development of advanced variational methods which play an important role in analytic and numerical studies of  1D and 2D quantum spin systems. Such methods are based on the ideas coming from the renormalization group theory which states that  physical properties of  spin systems become scale invariant near criticality. One of the most powerful variational algorithms is the corner-transfer matrices (CTM) method which allows to predict properties of large systems based on a simple iterative algorithm.
