Topological Theory of Classical and Quantum Phase Transition
Tieyan Si
We presented the topological current of Ehrenfest definition of phase transition. It is shown that different topology of the configuration space corresponds to different phase tran…
Spin-charge gauge symmetry: A way to tackle HTS cuprates?
P. A. Marchetti, Z. B. Su, L. Yu
We propose an explanation of several experimental features of transport phenomena in the normal state of high Tc cuprates in terms of a spin-charge gauge theory of the 2D t-J model…
In-plane substitution effect on the magnetic properties of two-dimensional Spin-gap system SrCu(BO)
G. T. Liu, J. L. Luo, Y. Q. Guo +5
A series of in-plane substituted compounds, including Cu-site (SrZnCu(BO)), and B-site (SrCu(SiBO)) substitution, were synthesized by so…
Hot and Cooled baryons in SPH simulations of galaxy clusters: physics and numerics
S. Borgani, K. Dolag, G. Murante +7
We discuss an extended set of Tree+SPH simulations of galaxy clusters, with the goal of investigating the interplay between numerical resolution effects and star-formation/feedback…
Conformal Triality of de Sitter, Minkowski and Anti-de Sitter Spaces
Bin Zhou, Han-Ying Guo
We describe how conformal Minkowski, dS- and AdS-spaces can be united into a single submanifold [N] of RP^5. It is the set of generators of the null cone in M^{2,4}. Conformal tran…
New Coordinates for BTZ Black Hole and Hawking Radiation via Tunnelling
Wenbiao Liu
Hawking radiation can usefully be viewed as a semi-classical tunnelling process that originates at the black hole horizon. For the stationary axisymmetric BTZ black hole, a general…
