Numerical simulations of quantum clock for measuring tunneling times
Fumika Suzuki, William G. Unruh
We numerically study two methods of measuring tunneling times using a quantum clock. In the conventional method using the Larmor clock, we show that the Larmor tunneling time can b…
Ginzburg effect in a dielectric medium with dispersion and dissipation
Sascha Lang, Roland Sauerbrey, Ralf Schützhold +1
As a quantum analog of Cherenkov radiation, an inertial photon detector moving through a medium with constant refractive index may perceive the electromagnetic quantum fluctuat…
Gravitational Redshift Tests with Atomic Clocks and Atom Interferometers
Fabio Di Pumpo, Christian Ufrecht, Alexander Friedrich +3
Atomic interference experiments can probe the gravitational redshift via the internal energy splitting of atoms and thus give direct access to test the universality of the coupling…
Quantum radiation in dielectric media with dispersion and dissipation
Sascha Lang, Ralf Schützhold, William G. Unruh
By a generalization of the Hopfield model, we construct a microscopic Lagrangian describing a dielectric medium with dispersion and dissipation. This facilitates a well-defined and…
The ambiguity function and the displacement operator basis in quantum mechanics
Jonathan S Ben-Benjamin, William G Unruh
We present a method for calculating expectation values of operators in terms of a corresponding c-function formalism which is not the Wigner--Weyl position-momentum phase-space, bu…
Scattering of a composite quasiparticle by an impurity on a lattice
Fumika Suzuki, Marina Litinskaya, William G. Unruh
We study scattering of a composite quasiparticle, which possesses a degree of freedom corresponding to relative separation between two bound excitations, by a delta-like impurity p…
