Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Extension of Kahler currents
Kahler-currents 扩展 解析奇点
2023/4/14
In this lecture I will talk about Collins-Tosatti's proof on the extension of Kahler currents with analytic singularities.
Electromagnetic fields in air of traveling-wave currents above the earth
Electromagnetic fields air of traveling-wave currents the earth
2015/10/16
The problem of the electromagnetic field created by a thin, straight conductor of infinite length carrying a forward traveling-wave current with a complex propagation constant g above a homogeneous an...

Two-dimensional highly directive currents large circular loops
2015/10/16
Properties of idealized, two-dimensional current distributions on circular loops are investigated analytically via the solution of a constrained optimization problem.The directivity in the far field i...
Chiral spin currents and spectroscopically accessible single merons in quantum dots

2011/9/9
We provide unambiguous theoretical evidence for the formation of correlation-induced isolated merons in rotationally-symmetric quantum dots. Our calculations rely on neither the lowest-Landau-level ap...
Neutrino Quasielastic Scattering on Nuclear Targets: Parametrizing Transverse Enhancement (Meson Exchange Currents)
Neutrino Quasielastic Nuclear Targets Parametrizing Transverse
2011/7/21
We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum tr...

We present a parametrization of the observed enhancement in the transverse electron quasielastic (QE) response function for nucleons bound in carbon as a function of the square of the four momentum tr...
We derive the Noether currents and charges associated with an internal galilean invariance---a symmetry recently postulated in the context of so-called galileon theories. Along the way we clarify the...

2010/12/24
Conformal low-spin anomalous currents and shadow fields in flat space-time of dimension greater than or equal to four are studied. Gauge invariant formulation for such currents and shadow fields is de...

2010/11/25
We analyze theoretically the bound state spectrum of an Aharonov Bohm (AB) ring in a twodimensional topological insulator using the four-band model of HgTe-quantum wells as a concrete example.
Full quantum calculation of the in-medium Cherenkov gluon emission by gluon current in transparent media without dispersion is discussed.

2010/10/22
We examine the problem of stability of persistent currents in a mixture of two Bose gases trapped in an annular potential. We evaluate the critical coupling for metastability in the transition from qu...
