Generalized black hole entropy in two dimensions [PDF]

open access: yesInternational Journal of Geometric Methods in Modern Physics (IJGMMP), 2023
The Bekenstein-Hawking entropy of a black hole is proportional to its horizon area, hence in $D=2$ spacetime dimensions it is constant because the horizon degenerates into two points.

Boundary Topological Entanglement Entropy in Two and Three Dimensions [PDF]

open access: yesCommunications in Mathematical Physics, 2020
The topological entanglement entropy is used to measure long-range quantum correlations in the ground space of topological phases. Here we obtain closed form expressions for the topological entropy of (2+1)- and (3+1)-dimensional loop gas models, both in

Persistent homology of collider observations: When (w)hole matters

open access: yesPhysics Letters B, 2023
Topological invariants have played a fundamental role in the advancement of theoretical high energy physics. Physicists have used several kinematic techniques to distinguish new physics predictions from the Standard Model (SM) of particle physics at ...

Holographic entropy inequalities and the topology of entanglement wedge nesting [PDF]

open access: yesPhysical Review D, 2023
We prove two new infinite families of holographic entropy inequalities. A key tool is a graphical arrangement of terms of inequalities that is based on entanglement wedge nesting.

Topological entropy on points without physical-like behaviour [PDF]

open access: yesMathematische Zeitschrift, 2018
We study a class of asymptotically entropy-expansive $C^1$ diffeomorphisms with dominated splitting on a compact manifold $M$, that satisfy the specification property. This class includes, in particular, transitive Anosov diffeomorphisms and time-one maps of transitive Anosov flows.

From Thermodynamics to Information: Landauer’s Limit and Negentropy Principle Applied to Magnetic Skyrmions

open access: yesFrontiers in Physics, 2022
Magnetic skyrmions are topological swirling spin textures objects that can be manipulated and employed as information carriers. This is accomplished based either on their ground-state properties or their thermodynamic properties.

Charge-resolved entanglement in the presence of topological defects [PDF]

open access: yesPhysical review B, 2023
Topological excitations or defects such as solitons are ubiquitous throughout physics, supporting numerous interesting phenomena like zero energy modes with exotic statistics and fractionalized charges.

Characterizations of Chemical Networks Entropies by K-Banhatii Topological Indices

open access: yesSymmetry, 2023
Entropy is a thermodynamic function in physics that measures the randomness and disorder of molecules in a particular system or process based on the diversity of configurations that molecules might take.

A black hole toy model with non-local and boundary modes from non-trivial boundary conditions

open access: yesEuropean Physical Journal C: Particles and Fields, 2023
We study gauge theories between two parallel boundaries with non-trivial boundary conditions, which serve as a toy model for black hole background with two boundaries near the horizon and infinite, aiming for a better understanding of the Bekenstein ...

Entropy Scaling Law and the Quantum Marginal Problem

open access: yesPhysical Review X, 2021
Quantum many-body states that frequently appear in physics often obey an entropy scaling law, meaning that an entanglement entropy of a subsystem can be expressed as a sum of terms that scale linearly with its volume and area, plus a correction term that
