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

Dynamics of global and local vortices with orientational moduli
Journal of High Energy Physics, 2021 The dynamics of both global and local vortices with non-Abelian orientational moduli is investigated in detail. Head-on collisions of these vortices are numerically simulated for parallel, anti-parallel and orthogonal internal orientations where we find ...

Instanton worldlines in five-dimensional Ω-deformed gauge theory
Journal of High Energy Physics, 2021 We discuss the Bosonic sector of a class of supersymmetric non-Lorentzian five-dimensional gauge field theories with an SU(1, 3) conformal symmetry. These actions have a Lagrange multiplier which imposes a novel Ω-deformed anti-self-dual gauge field ...

Fractional Skyrmion molecules in a ℂP N−1 model
Journal of High Energy Physics, 2021 We study fractional Skyrmions in a ℂP 2 baby Skyrme model with a generalization of the easy-plane potential. By numerical methods, we find stable, metastable, and unstable solutions taking the shapes of molecules.

Black holes, oscillating instantons and the Hawking-Moss transition
Journal of High Energy Physics, 2020 Static oscillating bounces in Schwarzschild de Sitter spacetime are investigated. The oscillating bounce with many oscillations gives a super-thick bubble wall, for which the total vacuum energy increases while the mass of the black hole decreases due to

Boundary metrics on soliton moduli spaces
Journal of High Energy Physics, 2022 The geodesic approximation is a powerful method for studying the dynamics of BPS solitons. However, there are systems, such as BPS monopoles in three-dimensional hyperbolic space, where this approach is not applicable because the moduli space metric ...

Journal of High Energy Physics, 2023 Q-lumps are spinning planar topological solitons with stationary solutions that satisfy first-order Bogomolny equations. Q-lump scattering has previously been studied only in the charge two sector, by approximating time evolution by motion in the moduli ...

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 ...

Stable Z-strings with topological polarization in two Higgs doublet model
Journal of High Energy Physics, 2022 We find that a Z-string is stable in a wide range of parameter space of the two Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z fluxes.
