We study the late-time behaviors of pseudo-(Rényi) entropy locally excited states in rational conformal field theories. To construct transition matrix, we utilize two nonorthogonal that are created by application different descendant operators to vacuum. show when generated a single Virasoro generator acting on same primary operator, excess pseudoentropy and pseudo-Rényi corresponds logarithm quantum dimension associated agreement with case entanglement entropy. However, for linear...

Abstract Experiments conducted on the J-TEXT tokamak have provided first evidence that Beta-induced Alfvén Eigenmode (BAE) is localized inside isolated helical flux tube of its edge m / n = 3/1 magnetic island. The observations show BAE forms a standing wave island, with nodes located at X- and O-points When island cut open by contact limiter plates, found to remain remnant closed in Scrape-Off Layer, but amplitude decreases as width becomes smaller.
<title>Abstract</title> Solar flares are driven by a rapid release of magnetic energy accumulated quasi-statically in the solar corona. This accumulation, magnetohydrodynamics processes, occurs macroscale systems, while its is governed kinetic effects at microscale. The vast separation system scales hinders understanding cross-scale cascades, leaving question how flare eruptions initiated unresolved. Here, we report laboratory experiments that replicate complete evolution coronal from...
