We investigate the collapse dynamics of a dipolar condensate of 52Cr atoms when the s-wave scattering length characterizing the contact interaction is reduced below a critical value. A complexâ€¦ (More)

We demonstrate that a matter-wave bright soliton can be stabilized in 2D free space by causing the strength of interactions to oscillate rapidly between repulsive and attractive by using, e.g.,â€¦ (More)

A gaseous Bose-Einstein condensate (BEC) offers an ideal te sting ground for studying symmetry breaking, because a trapped BEC system is in a mesos copic regime, and situations exist under whichâ€¦ (More)

The spin vortices are shown to be created through the Kibble-Zurek (KZ) mechanism in a quantum phase transition of a spin-1 ferromagnetic Bose-Einstein condensate, when the applied magnetic field isâ€¦ (More)

An exact diagonalization study reveals that a matter-wave bright soliton and the Goldstone mode are simultaneously created in a quasi-one-dimensional attractive Bose-Einstein condensate byâ€¦ (More)

The electronic structure of a prototype dilute magnetic semiconductor (DMS), Ga(1-x)MnxAs, is studied by magnetic circular dichroism (MCD) spectroscopy. We prove that the optical transitionsâ€¦ (More)

The dynamical instabilities and ensuing dynamics of singly and doubly quantized vortex states of BoseEinstein condensates with attractive interactions are investigated using full three-dimensionalâ€¦ (More)

One of the main aims in quantum optics has been to manipulate quantum-statistical properties of the electromagnetic field. Since the first milestone of generating squeezed state of light wasâ€¦ (More)

We report the first direct measurement of the hyperfine transition of the ground state positronium. The hyperfine structure between ortho-positronium and para-positronium is about 203 GHz. We developâ€¦ (More)

An attractive Bose-Einstein condensate with a vortex splits into two pieces via the quadrupole dynamical instability, which arises at a weaker strength of interaction than the monopole and the dipoleâ€¦ (More)
