Uniqueness of Two‐Bubble Wave Maps in High Equivariance Classes
Communications on Pure and Applied Mathematics, Volume 76, Issue 8, Page 1608-1656, August 2023., 2023 Abstract This is the second part of a two‐paper series that establishes the uniqueness and regularity of a threshold energy wave map that does not scatter in both time directions. Consider the S2‐valued equivariant energy critical wave maps equation on ℝ1+2, with equivariance class k≥4.

Area Law Saturation of Entropy Bound from Perturbative Unitarity in Renormalizable Theories
Fortschritte der Physik, Volume 69, Issue 1, January 2021., 2021 Abstract We study the quantum information storage capacity of solitons and baryons in renormalizable quantum field theories that do not include gravity. We observe that a 't Hooft‐Polyakov magnetic monopole saturates the Bekenstein bound on information when the theory saturates the bound on perturbative unitarity.

Unitarity Entropy Bound: Solitons and Instantons
Fortschritte der Physik, Volume 69, Issue 1, January 2021., 2021 Abstract We show that non‐perturbative entities such as solitons and instantons saturate bounds on entropy when the theory saturates unitarity. Simultaneously, the entropy becomes equal to the area of the soliton/instanton. This is strikingly similar to black hole entropy despite absence of gravity. We explain why this similarity is not an accident. We

Topological sectors for heterotic M5-brane charges under Hypothesis H
Journal of High Energy Physics, 2020 Assuming Fiorenza-Sati-Schreiber’s Hypothesis H, on the charge quantization of M-theory’s C -field, the topological sectors of the resulting String c2 (4)-valued higher gauge theory on a heterotic M5-brane are classified by homotopy classes of maps from ...

Instantons and entanglement entropy
Journal of High Energy Physics, 2017 We would like to put the area law — believed to be obeyed by entanglement entropies in the ground state of a local field theory — to scrutiny in the presence of nonperturbative effects.

False vacuum decay in gauge theory
Journal of High Energy Physics, 2017 The decay rate of a false vacuum is studied in gauge theory, paying particular attention to its gauge invariance. Although the decay rate should not depend on the gauge parameter ξ according to the Nielsen identity, the gauge invariance of the result of ...

Charge-Swapping Q-balls and Their Lifetimes
Journal of High Energy Physics, 2021 For scalar theories accommodating spherically symmetric Q-balls, there are also towers of quasi-stable composite Q-balls, called charge swapping Q-balls (CSQs).

Heun Functions and Some of Their Applications in Physics
Advances in High Energy Physics, Volume 2018, Issue 1, 2018., 2018 Most of the theoretical physics known today is described by using a small number of differential equations. For linear systems, different forms of the hypergeometric or the confluent hypergeometric equations often suffice to describe the system studied.

Revisit on two-dimensional self-gravitating kinks: superpotential formalism and linear stability
Journal of High Energy Physics, 2021 Self-gravitating kink solutions of a two-dimensional dilaton gravity are revisited in this work. Analytical kink solutions are derived from a concise superpotential formalism of the dynamical equations.

Supersymmetric Quantum Mechanics and Topology
Advances in High Energy Physics, Volume 2016, Issue 1, 2016., 2016 Supersymmetric quantum mechanical models are computed by the path integral approach. In the β → 0 limit, the integrals localize to the zero modes. This allows us to perform the index computations exactly because of supersymmetric localization, and we will show how the geometry of target space enters the physics of sigma models resulting in the ...
