<正> The sigma meson production in p + ~(12)C and p + ~(40)Ca reactions at the incident energy E_p=1.5 GeV isinvestigated within the Quantum Molecular Dynamics
<正> In similar to the derivation of phase angle operator conjugate to the number operator by Arroyo Carrasco-Moya Cessay we deduce the Hermitian phase operator
<正> We calculate the Casimir force at a finite cut-off Λ by summing the forces induced by the all fluctuationmodes.We show that the Casimir force is independe
<正>Based on the complex three-component order parameter model of a spin-triplet superconductor,by using the φ-mapping theory,we derive a new equation describi
