The observed recurrence of glitches in pulsars and neutron stars carries rich information about the evolution of their internal structures. In this article, I s
A series of compounds Ba5-xSrxGdTi3V7O30 (x = 0 - 5), belonging to tungsten bronze family were prepared by a high-temperature solid-state reaction route. Using
We theoretically investigate the quantum states of a Hamiltonian model for quasi-one-dimensional ultracold trapped gases. From the ansatz given by the numerical
Gravitation in flat space-time is described as field and studied in several articles. In addition to the flat space-time metric a quadratic form formally simila
Einstein’s Special Theory of Relativity (SR) relates time dilation to the velocity between the observer and the observed object as if they are identical. Our n
