Discovery of the High‐Entropy Carbide Ceramic Topological Superconductor Candidate (Ti0.2Zr0.2Nb0.2Hf0.2Ta0.2)C [PDF]
Advanced Functional Materials, 2023 High‐entropy ceramics (HECs) are solid solutions of inorganic compounds with one or more Wyckoff sites shared by equal or near‐equal atomic ratios of multi‐principal elements.

Generalized black hole entropy in two dimensions [PDF]
International 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]
Communications 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
Physics 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]
Physical 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.

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

Entanglement in the quantum Hall fluid of dipoles
SciPost Physics, 2021 We revisit a model for gapped fractonic order in (2+1) dimensions (a symmetric-traceless tensor gauge theory with conservation of dipole and trace-quadrupole moments described in \cite{Prem:2017kxc}) and compute its ground-state entanglement entropy on $\
