Semiclassical phases of charged spin- matter-wave interferometers in gravitational wave backgrounds
Nontapat Wanwieng, Apimook Watcharangkool
A matter wave propagating through curved spacetime accumulates phase that encodes both geometry and gauge structure. We develop a semiclassical framework for charged spin- mat…

Gravitational Wave Effects on Radio Spectral Lines of Atomic Hydrogen: Hyperfine Splitting and Broadening Mechanisms
Nontapat Wanwieng, Nithiwadee Thaicharoen, Narupon Chattrapiban +1
We explore the effects of gravitational waves (GWs) on hydrogen's radio spectral lines, focusing on the ground-state hyperfine transition and radiative transitions in highly excite…
