A Proposed Superconductivity Theory Receives Exclusive Experimental Confirmation
Superconductivity Theory Experimental Confirmation
2016/3/14
Superconductivity–a quantum phenomenon in which metals below a certain temperature develop flow of current with no loss or resistance–is one of the most exciting problems in physics, which has resulte...

Membrane separation overlapping cross membrane membrane cross membrane
2014/12/22
We construct new supersymmetric solutions of D = 11 supergravity describing n orthogonally “overlapping” membranes and fivebranes for n = 2,…,8. Overlapping branes arise after separating intersecting ...

2012/2/27
The effect of interface scattering on the performance of disordered, nanocomposite thermoelectric materials is studied theoretically using effective medium theory and direct numerics. The interfacial ...
Corrections to the Coulomb pseudopotential in the theory of superconductivity

2012/2/27
We calculate corrections to the conventional result for the Coulomb pseudopotential in the theory of superconductivity. We find that retardation effects are still operative for higher order correction...

2010/12/21
In this paper, we study nucleation of vacuum bubbles in the Brans-Dicke type theory of
gravity. In the Euclidean signatures, we calculate field combinations of vacuum bubbles as

We develop an Eliashberg theory for ferromagnetic quantum criticality in the surface of three
dimensional topological insulators. A novel ingredient of the present study is to introduce an

2010/11/23
In this work, we theoretically construct exact mappings of many-particle bosonic systems onto
quantum rotor models. In particular, we analyze the rotor representation of spinor Bose-Einstein condensa...

Theory of Valley-Density Wave Iron-Pnictides
2010/11/19
In the limit of perfect nesting, the physics of iron-pnictides is governed by the density wave
formation at the zone-edge vector M. At high energies, various spin- (SDW), charge- (CDW),
orbital/pock...
