The mean-field phi4-model: entropy, analyticity, and configuration space topology [PDF]

, 2005
A large deviation technique is applied to the mean-field phi4-model, providing an exact expression for the configurational entropy s(v,m) as a function of the potential energy v and the magnetization m.

Systolic aspects of black hole entropy

, 2020
We attempt to provide a mesoscopic treatment of the origin of black hole entropy in (3+1)-dimensional spacetimes. We ascribe this entropy to the non-trivial topology of the space-like sections $\Sigma$ of the horizon. This is not forbidden by topological

2+1 Black Hole with a Dynamical Conical Singularity [PDF]

, 1996
We find black hole solutions to Euclidean 2+1 gravity coupled to a relativistic particle which have a dynamical conical singularity at the horizon.

Nonlinear walkers and efficient exploration of congested networks

Physical Review Research, 2020
Random walks are the simplest way to explore or search a graph and have revealed a very useful tool to investigate and characterize the structural properties of complex networks from the real world.

Detecting topology change via correlations and entanglement from gauge/gravity correspondence [PDF]

, 2017
We compute a momentum space version of the entanglement spectrum and entanglement entropy of general Young tableau states and one-point functions on Young tableau states.

Multi-boundary entanglement in Chern-Simons theory and link invariants

Journal of High Energy Physics, 2017
We consider Chern-Simons theory for gauge group G at level k on 3-manifolds M n with boundary consisting of n topologically linked tori. The Euclidean path integral on M n defines a quantum state on the boundary, in the n-fold tensor product of the torus

Can Extremal Black Holes Have Non-Zero Entropy ? [PDF]

, 1996
We give several pieces of evidence to show that extremal black holes cannot be obtained as limits of non-extremal black holes. We review arguments in the literature showing that the entropy of extremal black holes is zero, while that of near-extremal ...

Bubbling Supertubes and Foaming Black Holes

, 2006
We construct smooth BPS three-charge geometries that resolve the zero-entropy singularity of the U(1) x U(1) invariant black ring. This singularity is resolved by a geometric transition that results in geometries without any branes sources or ...

Complex Networks and Symmetry I: A Review [PDF]

, 2010
In this review we establish various connections between complex networks and symmetry. While special types of symmetries (e.g., automorphisms) are studied in detail within discrete mathematics for particular classes of deterministic graphs, the analysis ...
