Berezinskii-Kosterlitz-Thouless Transition in Two-Dimensional Dipole Systems
Super fluid fluid dipolar bosons path integral monte carlo simulation high density temperature particle excitation spectrum
2014/12/18
The superfluid to normal fluid transition of dipolar bosons in two dimensions is studied in a broad density range by using path integral Monte Carlo simulations and summarized in the phase diagram. Wh...
Spatially probed electron-electron scattering in a two-dimensional electron gas
Spatially probed electron-electron two-dimensional electron gas
2010/11/17
Using scanning gate microscopy (SGM), we probe the scattering between a beam of electrons and a
two-dimensional electron gas (2DEG) as a function of the beam's injection energy, and distance from the...
Observation of two-dimensional superlattice solitons
two-dimensional superlattice soliton shallow waveguides superlattices
2010/4/8
We observe experimentally two-dimensional solitons in superlattices comprising alternating deep and shallow waveguides fabricated via the femtosecond laser direct writing technique. We find that the s...
