A Rastall Scalar-Tensor theory
T. Caramês, M. H. Daouda J. C. Fabris, A. M. Oliveira +2
We formulate a theory combining the principles of a scalar-tensor gravity and the Rastall proposal of a violation of the usual conservation laws. In the resulting Brans-Dicke-Rasta…
On convergence to equilibrium in strongly coupled Bogoliubov's oscillator model
V. Strokov
We examine classical Bogoliubov's model of a particle coupled to a heat bath which consists of infinitely many stochastic oscillators. Bogoliubov's result suggests that, in the sto…
Cosmological status of Lagrangian theory of density perturbations
V. Strokov
We show that hydrodynamical and field approaches in theory of cosmological scalar perturbations are equivalent for a single medium. We also give relations between notations introdu…
Perihelion precession and deflection of light in gravitational field of wormholes
V. Strokov, S. Repin
Quite exotic relativistic objects known as wormholes are hypothetical candidates for central machine of active galactic nuclei as well as black holes. We find the magnitude of the…
Altermagnetic lifting of Kramers spin degeneracy
J. Krempaský, L. Šmejkal, S. W. D'Souza +20
Lifted Kramers spin-degeneracy has been among the central topics of condensed-matter physics since the dawn of the band theory of solids. It underpins established practical applica…
Observation of Weyl nodes in TaAs
B. Q. Lv, N. Xu, H. M. Weng +14
In 1929, H. Weyl proposed that the massless solution of Dirac equation represents a pair of new type particles, the so-called Weyl fermions [1]. However the existence of them in pa…
