Magnetic relaxation in large spin molecular paramagnets is often found to behave as δM(t) ∼ √ t at short times t. This behaviour was explained by Prokofiev & Stamp as arising from dipole interactions between molecular spins. However, as observed by Miyashita & Saito, the same behaviour can arise from a different mechanism which, in the present work, is related to hyperfine interactions. The Miy...
The notion of complex energy landscape underpins the intriguing dynamical behaviors in many complex systems ranging from polymers, to brain activity, to social networks and glass transitions. The spin glass state found in dilute magnetic alloys has been an exceptionally convenient laboratory frame for studying complex dynamics resulting from a hierarchical energy landscape with rugged funnels. ...
Very low temperature dilute trapped atomic gases form a well known state, the Bose-Einstein condensate (BEC). Recent work has made it possible to adiabatically transfer condensates from 3 dimensional traps into RF dressed traps that hold the atoms in a small region around a specific magnetic field. For a quadrupole magnetic trap, this results in an ”eggshell” potential, where atoms’ movement is...
