Dark Energy and Dark Matter unification via superfluid Chaplygin gas
V. A. Popov
A new model describing the dark sector of the universe is established. The model involves Bose-Einstein condensate (BEC) as dark energy (DE) and an excited state above it as dark m…
Spin-Orbit Qubits of Rare-Earth-Metal Ions in Axially Symmetric Crystal Fields
Sylvain Bertaina, J. H. Shim, S. Gambarelli +2
Contrary to the well known spin qubits, rare-earth qubits are characterized by a strong influence of crystal field due to large spin-orbit coupling. At low temperature and in the p…
Algorithms for Quantum Branching Programs Based on Fingerprinting
Farid Ablayev, Alexander Vasiliev
In the paper we develop a method for constructing quantum algorithms for computing Boolean functions by quantum ordered read-once branching programs (quantum OBDDs). Our method is…
Non-minimal coupling of photons and axions
Alexander B. Balakin, Wei-Tou Ni
We establish a new self-consistent system of equations accounting for a non-minimal interaction of gravitational, electromagnetic and axion fields. The procedure is based on a non-…
On the nature of pulse profile variations and timing noise in accreting millisecond pulsars
Juri Poutanen, Askar Ibragimov, Marja Annala
Timing noise in the data on accretion-powered millisecond pulsars (AMP) appears as irregular pulse phase jumps on timescales from hours to weeks. A large systematic phase drift is…
Frequency and Phase Synchronization in Neuromagnetic Cortical Responses to Flickering-Color Stimuli
S. F. Timashev, Yu. S. Polyakov, R. M. Yulmetyev +4
In our earlier study dealing with the analysis of neuromagnetic responses (magnetoencephalograms - MEG) to flickering-color stimuli for a group of control human subjects (9 volunte…
