Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Global strong solutions to the two-dimensional radially symmetric compressible MHD
二维径向对称 可压缩 磁流体动力学 全局强解
2023/12/11
In this talk, I will present our recent result the 2D radially symmetric compressible MHD with density-dependent viscosity. Under the condition of beta>1, we prove the global existence of the radially...
Unconventional Rotational Responses of Hadronic Superfluids in a Neutron Star Caused by Strong Entrainment and a Σ- Hyperon Gap
Neutron star spinning reaction model whirlpool proton vortex a charged condenser coil
2014/12/19
I show that the usual model of the rotational response of a neutron star, which predicts rotation-induced neutronic vortices and no rotation-induced protonic vortices, does not hold (i) beyond a certa...
Carrier heating and high-order harmonics generation in doped graphene by a strong ac electric field
Carrier heating high-order harmonics generation strong ac electric field
2010/11/25
The nonlinear response of electrons (holes) in doped graphene on ac pumping is concidered the-
oretically for the frequency region above the energy relaxation rate but below the momentum and
carrier...
Strong coupling treatment of the polaronic system consisting of an impurity in a condensate
Other Bose-Einstein condensation phenomena
2010/11/18
The strong coupling treatment of the Fr¨ohlich-type polaronic system, based on a canonical
transformation and a standard Landau-Pekar type variational wave function, is applied to the
polaronic syst...
Helical modes in carbon nanotubes generated by strong electric fields
Helical modes carbon nanotubes generated
2010/11/23
Helical modes, conducting opposite spins in opposite directions, are shown to exist in metallic
armchair nanotubes in an all-electric setup. This is a consequence of the interplay between spinorbit i...
We performed inelastic neutron scattering on powder sample of the P-doped iron-based super-
conductor BaFe2(As0.65P0.35)2 with Tc = 30 K, whose superconducting (SC) order parameter is
expected to ha...
Density of states of a graphene in the presence of strong point defects
graphene strong point defects
2010/11/19
The density of states near zero energy in a graphene due to strong point defects with random
positions are computed. Instead of focusing on density of states directly, we analyze eigenfunctions of in...
Optical investigations of the chemical pressurized EuFe2(As1-xPx)2: an s-wave superconductor with strong interband interaction
Optical investigations s-wave superconductor interband interaction
2010/11/18
Superconducting EuFe2(As0.82P0.18)2 single crystals are investigated by infrared spectroscopy in a wide frequency range. Below Tc = 28 K a superconducting gap forms at 20 = 9.5 meV = 3.8kBTc causing ...
Exploration of the phase structure of $SU(N_c)$ lattice gauge theory with many Wilson fermions at strong coupling

2011/1/13
We explore aspects of the phase structure of SU(2) and SU(3) lattice gauge theories at strong
coupling with many flavours Nf of Wilson fermions in the fundamental representation, including
the relev...
