Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Transport properties of Gaussian measures for nonlinear Schrodinger equations
非线性 薛定谔方程 高斯测度 输运性质
2023/11/13
In the statistical study of Hamiltonian PDEs out of the equilibrium (lack of invariant measures), it is a natural question to understand the transport properties for canonical Gaussian measures. The f...
Observation of Unusual Mass Transport in Solid hcp 4He
Stop the capillary constant temperature superfluid solid atoms the melting curve
2014/12/20
Solid 4He has been created off the melting curve by growth at a nearly constant mass via the “blocked capillary” technique and growth from the 4He superfluid at constant temperature. The experimental ...
Observation of mass transport through solid 4He
Superfluid helium cells solid temperature
2014/12/19
By use of an experimental design that provides for superfluid helium in contact with bulk hcp 4He off the melting curve, we have observed the dc transport of mass through a cell filled with solid 4He ...

2014/5/28
Motivated by several recent experiments, we investigate phonon-assisted electronic transport through suspended carbon nanotube quantum dots including electron-electron, electron-phonon, and spin-orbit...

Resonantly Enhanced Tunneling and Transport of Ultracold Atoms on Tilted Optical Lattices
Tunneling Ultracold Atoms Tilted Optical Lattices
2011/9/9
We investigate the resonantly enhanced tunneling dynamics of ultracold bosons loaded on a tilted 1-D optical lattice, which can be used to simulate a chain of Ising spins and associated quantum phase ...
The shear () and bulk () viscous coefficients have been evaluated for a gluonic fluid. The elastic,gg ! gg and the inelastic, number non-conserving, gg ! ggg processes have been considered as the do...
Hydrodynamic description of transport in strongly correlated electron systems
Hydrodynamic description strongly correlated electron systems
2010/11/22
We develop a hydrodynamic description of the resistivity and magnetoresistance of an electron
liquid in a smooth disorder potential. This approach is valid when the electron-electron scattering lengt...
Conservation laws, integrability and transport in one-dimensional quantum systems
Conservation laws one-dimensional quantum systems
2010/11/18
In integrable one-dimensional quantum systems an infinite set of local conserved quantities exists which can prevent a current from decaying completely. For cases like the spin current in the XXZ mode...

2010/11/8
Quantum transmission spectra of a twisted electron waveguide expose the coupling between traveling and quasi-bound states. Through a direct numerical solution of the open-boundary Schr\"odinger equati...

2010/11/18
We investigate the spin-polarized transport of GaMnAs nanolayers in which a ferromagnetic order
exists below a certain transition temperature. Our calculation for the self-averaged resistivity takes ...
