On link invariants and topological string amplitudes
P. Ramadevi,Tapobrata Sarkar +1 more
TL;DR: In this article, it was shown that the new polynomial invariants for knots, upto nine crossings, agree with the Ooguri-Vafa conjecture relating Chern-Simons gauge theory to topological string theory on the resolution of the conifold.
Journal ArticleDOI
On the thermodynamic geometry of BTZ black holes
TL;DR: In this article, the authors investigated the Ruppeiner geometry of the thermodynamic state space of a general class of BTZ black holes and established that the inclusion of thermal fluctuations induces a non zero scalar curvature to the thermodynamics geometry.
Journal ArticleDOI
Thermodynamic Geometry, Phase Transitions, and the Widom Line
TL;DR: A microscopic characterization, based on the thermodynamic curvature R, is proposed for first-order liquid-gas phase transitions near the critical point, where R is proportional to the correlation volume ξ(3), and allows a direct determination of the Widom line in the supercritical regime.
Journal ArticleDOI
On the Thermodynamic Geometry and Critical Phenomena of AdS Black Holes
TL;DR: In this paper, the authors studied various aspects of the equilibrium thermodynamic state space geometry of AdS black holes and provided important new insights into the structure and significance of the scalar curvature.
Journal ArticleDOI
Thermodynamic geometry and phase transitions in Kerr-Newman-AdS black holes
TL;DR: In this paper, the scalar curvature of the Kerr-Newman-Anti de Sitter (KN-AdS) black holes is computed in various ensembles, and it is shown that the curvature diverges at the critical point of second order phase transitions for these systems.
