DESCRIPTION:Speakers: Nontapat Wanwieng\nWe present a partial combination
of general relativistic framework to the relativistic quantum mechanics of
spin-1/2 particles for a study of the gravitational effects in quantum me
chanical phenomena. We focus on the case of Dirac particles under the infl
uence of gravitational waves (GWs) in low-energy limit. From our approach\
, GWs are modeled simply as a plane waves which described by Linearized Ei
nstein Field Equations (LEFEs) and Dirac particles are\, of course\, descr
ibed by Dirac Equation (DE). To incorporate the effects of gravity into th
e Dirac theory in an appropriate manner\, it is assumed to be sufficient t
o invoke the principle of minimal coupling\, promoting the Dirac equation
to be valid in general curved spacetime. We also introduce electromagnetic
interaction through the minimal coupling as well. Then we derive the Hami
ltonian\, which determines dynamics of our system in a non-relativistic li
mit with relativistic correction terms. Consequently\, we are able to use
the standard Perturbation Theory (PT) to study effects due to gravitationa
l wave in various aspects.\nhttps://indico.narit.or.th/event/146/
