Модифицированная модель ньютоновского тяготения
Within the limits of the classical mechanics for planets of the Solar system a new form of gravitational potential is suggested. The following effects are considered: perihelion advance of the planets, deviation of light beams in the field of the Sun, and gravitational displacement of spectral lines.В рамках классической механики для планет Солнечной системы предлагается новая форма гравитационного потенциала. Рассмотрены следующие эффекты: смещение перигелия планет, отклонение световых лучей в поле Солнца, гравитационное смещение спектральных линий
NbS: A unique quasi one-dimensional conductor with three charge density wave transitions
Through transport, compositional and structural studies, we review the
features of the charge-density wave (CDW) conductor of NbS (phase II). We
highlight three central results: 1) In addition to the previously reported CDW
transitions at = 360\,K and = 150\,K, another CDW transition
occurs at a much higher temperature = 620-650\,K; evidence for the
non-linear conductivity of this CDW is presented. 2) We show that CDW
associated with the - transition arises from S vacancies acting as
donors. Such a CDW transition has not been observed before. 3) We show
exceptional coherence of the -CDW at room-temperature. Additionally, we
report on the effects of uniaxial strain on the CDW transition temperatures and
transport.Comment: 16 pages, 18 figure
