Equivalence of scalar-tensor theories and scale-dependent gravity
Philipp Neckam, Christian Käding, Benjamin Koch +4
We present a novel equivalence between scale-dependent gravity and scalar-tensor theories that have only a single scalar field with a canonical kinetic term in the Einstein frame a…

Frequency shifts induced by light scalar fields
Christian Käding
Light scalar fields are frequently used in modern physics, for example, as candidates for dark energy or dark matter. Open quantum dynamical effects, like frequency shifts, induced…

Specifying the unitary evolution of a qudit for a general nonstationary Hamiltonian via the generalized Gell-Mann representation
Elena R. Loubenets, Christian Käding
Optimal realizations of quantum technology tasks lead to the necessity of a detailed analytical study of the behavior of a -level quantum system (qudit) under a time-dependent H…
