Given a Cauchy surface in a curved spacetime and a suitably defined quantum state on the CCR algebra of the Klein Gordon quantum field on that surface, we show, by expanding the squared spacetime geodesic distance and the '$U$' and '$V$' Hadamard coe

Defects in crystals can have a transformative effect on the properties and functionalities of solid-state systems. Dopants in semiconductors are core components in electronic and optoelectronic devices. The control of single color centers is at the b

Hawking showed that a black hole formed by collapse will emit radiation and eventually disappear. We address the challenge to define an objective notion of physical entropy which increases throughout this process in a way consistent with unitarity. W
