Bulk-boundary thermodynamic equivalence: a topology viewpoint [PDF]
Journal of High Energy Physics, 2023 Setting the cosmological constant to be dynamical, we study the bulk and boundary thermodynamics of charged Anti-de Sitter black holes. We develop mass/energy formulas in terms of thermodynamic state functions for the extended thermodynamics, mixed ...

Topology of critical points in boundary matrix duals [PDF]
Journal of High Energy Physics, 2023 Computation of topological charges of the Schwarzschild and charged black holes in AdS in canonical and grand canonical ensembles allows for a classification of the phase transition points via the Bragg-Williams off-shell free energy.

Hermitian Bulk – Non-Hermitian Boundary Correspondence [PDF]
PRX Quantum, 2023 Non-Hermitian band theory distinguishes between line gaps and point gaps. While point gaps can give rise to intrinsic non-Hermitian band topology without Hermitian counterparts, line-gapped systems can always be adiabatically deformed to a Hermitian ...

Chiral Dirac superconductors: Second-order and boundary-obstructed topology [PDF]
Physical Review Research, 2020 We analyze the topological properties of a chiral p+ip superconductor for a two-dimensional metal and semimetal with four Dirac points. Such a system has been proposed to realize second-order topological superconductivity and host corner Majorana modes ...

Topology Adaptive Water Boundary Extraction Based on a Modified Balloon Snake: Using GF-1 Satellite Images as an Example [PDF]
Remote Sensing, 2017 Topology adaptive water boundary extraction from satellite images using parametric snakes remains challenging in the domain of image segmentation. This paper proposed a modified balloon snake (MB-Snake) method based on the balloon snake (B-Snake) method,

Smooth boundary topology optimization applied to an electrostatic actuator [PDF]
, 2008 Smooth boundary topology optimization (SBTO) avoids many of the problems encountered by conventional cell based systems coupled with material homogenization or density method. Shape optimization becomes part of topology optimization. The effectiveness of

Observation of momentum-gap topology of light at temporal interfaces in a time-synthetic lattice [PDF]
Nature CommunicationsTopological phases have prevailed across diverse disciplines, spanning electronics, photonics, and acoustics. Hitherto, the understanding of these phases has centred on energy (frequency) bandstructures, showcasing topological boundary states at spatial ...

Topology and dynamics of the contracting boundary of cocompact CAT(0) spaces [PDF]
Pacific Journal of Mathematics, 2019 Let $X$ be a proper CAT(0) space and let $G$ be a cocompact group of isometries of $X$ which acts properly discontinuously. Charney and Sultan constructed a quasi-isometry invariant boundary for proper CAT(0) spaces which they called the contracting ...

Boundary dynamics and topology change in quantum mechanics [PDF]
, 2015 We show how to use boundary conditions to drive the evolution on a Quantum Mechanical system. We will see how this problem can be expressed in terms of a time-dependent Schr\"{o}dinger equation.
