Operator Ordering in the Relativistic Quantization: Specific Heat in the Rindler Frame
Karol Sajnok, Kacper Dębski
We introduce a covariant canonical quantization for a particle in curved spacetime that tracks operator-ordering ambiguities. Parameterizing spatial and temporal ordering, we deriv…

Measuring the Casimir-Polder potential with Unruh-DeWitt detector excitations
Kacper Dębski, Piotr T. Grochowski, Andrzej Dragan
We propose a new method to measure Casimir-Polder force in an optical cavity by means of atomic excitations. We utilize a framework in which Unruh-DeWitt Hamiltonian mimics the ful…

Multimode theory of Gaussian states in uniformly accelerated frames
Kacper Dębski, Andrzej Dragan
We use the formalism of noisy Gaussian channels to derive explicit transformation laws describing how an arbitrary multimode Gaussian state of a scalar quantum field is perceived b…
