Solving the Dirac equation in a two-dimensional spacetime background with a kink
… following paper, I study the Dirac equation in curved spacetime and solve this equation in two-dimensional spacetime backgrounds discovered by Jackiw et al[4], [5]. I will first discuss flat spacetime and introduce the Dirac equation, which describes the relativistic wavefunctions of spin-1/2 …

Cyclic universes & direct detection of cosmic expansion by holonomy in the McVittie spacetime
… transfer of a vector around a closed loop in a curved spacetime. Generally, expansion would cause a measurable deficit angle between the vector’s initial and final positions. Using the McVittie spacetime (which describes a spherically symmetric object in an expanding universe) as a backdrop to …

Perturbative Quantum Gravity and Yang-Mills Theories in de Sitter Spacetime
… theories and perturbative quantum gravity in curved spacetime. In the second part we calculate the Feynman propagators of the Faddeev- Popov ghosts for Yang-Mills theories and perturbative quantum gravity in the covariant gauge. In the third part we investigate the physical equivalence of …

From Measure Zero to Measure Hero: Periodic Kerr Orbits and Gravitational Wave Physics
… the most fundamental prediction of a theory of curved spacetime - looms close at hand. Stellar mass compact objects spiraling into supermassive black holes have received particular attention as sources of gravitational waves detectable by space-based gravitational wave observatories. A …

Paracausal deformations, M{\o}ller operators, and Hadamard states in CCR AQFT.
… and algebraic quantum field theories in curved spacetime. In particular, the main question is: how do the theories change under finite global variations of the spacetime metric tensor? To answer this question a new deformation tool, the paracausal deformation, is developed and studied on …

Gyroscropes Orbiting Gargantuan Black Holes: Spinning Secondaries in Extreme Mass Ratio Inspirals
… a geodesic of the more massive black hole's spacetime. Post-geodesic effects are needed to model the system accurately. Failure to incorporate these effects can introduce bias in tests of general relativity and compromise precision measurement of the larger black hole's properties. One very …

Quantum Fields on BTZ Black Holes
… specifically, we study how a ground state in AdS spacetime becomes a thermal state when restricted to the exterior region of the BTZ black hole. This ground state is for the quantum linear real scalar field which satisfies the Klein-Gordon equation and also, in the 1+2 dimensional case, for a …

On the parallels between the Maxwell and Dirac equations
… Dirac equations. Within this new framework, the spacetime itself is a second--order covariant or contravariant spinor. Furthermore, the electronic field is naturally identified as a spinor (first--order spinor), whereas the electromagnetic field emerges as a second--order mixed spinor. We further …
