    Quantum phase transitions with parity-symmetry breaking and hysteresis

    An ultracold gas trapped in a symmetric double-well potential should populate both wells equally; however, the gas spontaneously localizes in one well when the interaction between atoms reaches a critical valu...

    Measurement of the mobility edge for 3D Anderson localization

    Anderson localization is a universal phenomenon affecting non-interacting quantum particles in a disordered environment. In three spatial dimensions, theory predicts a quantum phase transition from localizatio...

    EXOSAT observations of late-type stars: The application of coronal loop models

    We apply solar-type coronal loop models to X-ray and UV observations of late-type stars. We derive from EXOSAT and IUE observations constraints on the temperature, pressure and size of the emitting structures.
