Superconductivity in SrTiO: dielectric function method for non-parabolic bands
S. N. Klimin, J. Tempere, J. T. Devreese +3
The dielectric function method for superconductivity has been applied to SrTiO accounting for the non-parabolic dispersion of charge carriers in the conduction band and for t…
Infinite arc-transitive and highly-arc-transitive digraphs
Rögnvaldur G. Möller, Primož Potočnik, Norbert Seifter
A detailed description of the structure of two-ended arc-transitive digraphs is given. It is also shown that several sets of conditions, involving such concepts as Property Z, loca…
Sharply -arc-transitive-digraphs: finite and infinite examples
Rögnvaldur G. Möller, Primož Potočnik, Norbert Seifter
A general method for constructing sharply -arc-transitive digraphs, i.e. digraphs that are -arc-transitive but not -arc-transitive, is presented. Using our method it i…
Relativistic interaction of long-wavelength ultrashort laser pulses with nanowires
Z. Samsonova, S. Höfer, V. Kaymak +11
We report on experimental results in a new regime of a relativistic light-matter interaction employing mid-infrared (3.9-micrometer wavelength) high-intensity femtosecond laser pul…
study of (=Ba, Sr, Ca) under high pressure
Andriy Smolyanyuk, Cesare Franchini, Lilia Boeri
Using crystal structure prediction we study the high-pressure phase diagram of bismuthates (=Ba, Sr, Ca) in a pressure range up to 100G…
Gravitational fragmentation and formation of giant protoplanets on tens-of-au orbits
Eduard I. Vorobyov, Vardan Elbakyan
Migration of dense gaseous clumps that form in young protostellar disks via gravitational fragmentation is investigated to determine the likelihood of giant planet formation. High-…
