Mass and decay angles in the -- mixing tension: Virtual hybrids and a single-direction criterion
Sanghoon Kim, Gihwan Nam, Jongheon Baek
We compare three definitions of -- mixing within a constituent-quark model: a spin-component probability angle, a common-source overlap angle, and an SU(3)-breaking mass…

Spectral Crossings Diagnose Multiply Quantized Vortex Splitting
Jongheon Baek, Hiroyuki Tajima, Gihwan Nam
A charge- coupling vortex can remain as one fused order- zero or split into nearby unit-charge zeros after weak symmetry breaking. The two configurations have the same to…

Exact horizon response and charge ensembles of Majumdar--Papapetrou black holes
Jongheon Baek, Gihwan Nam
We determine the electrostatic Dirichlet-to-Neumann map of an arbitrary four-dimensional Majumdar--Papapetrou spacetime. For a minimally coupled spectator Maxwell field, the potent…
