Superradiance and Quasinormal Modes of Massive Scalar Fields around Kerr Black Holes in Einstein-Maxwell-Dilaton-Axion Theory with Perfect Fluid Dark Matter
Teparksorn Pengpan
We investigate the dynamics of massive scalar fields around Kerr black holes in the Einstein-Maxwell-dilaton-axion (EMDA) theory, incorporating the effects of perfect fluid dark ma…

Entanglement signature of fully and partially dimerized phases in frustrated spin chains
Wuttichai Pankeaw, Teparksorn Pengpan, Pruet Kalasuwan
The von Neumann entanglement entropy of exact valence-bond ground states is studied in two frustrated one-dimensional spin chains: the spin-1/2 Majumdar-Ghosh (MG) model and the sp…
