Magnetic quantum oscillations have been unexpectedly observed in insulators, where freely moving charge carriers are not ...

In recent 90 years, neutrino physics has been one of the most curious and hotly debated topics in particle physics and cosmology. We are faced with many unsolved problems in this area yet. Without ...

In this study, a novel adapted homotopy perturbation method (HPM) is used to treat the nonlinear phenomena of free vibration in a system with one degree of freedom. This adaptation involves the ...
