Nonrelativistic spin 12 particle in an arbitrary non - Abelian magnetic field in two spatial dimensions
The (group and spin space) matrix Hamiltonian describing the dynamics of a nonrelativistic spin 1/2 particle moving in a static, but spatially dependent, non-Abelian magnetic field in two spatial dimensions is shown to take the form of an anticommutator of a nilpotent operator and its hermitian conjugate. Consequently, the (group space) matrix Hamiltonians for the two different spin projections...
متن کامل12 hz electromagnetic field changes stress-related hormones of rat
due to the increasing presence of electromagnetic radiation in advanced societies, investigation of the effects of this radiation on humans has attracted the interest of many researchers. the non- ionizing radiation can induce numerous effects through biomolecules in the tissue and cells. in the current study, effects of 12 hz electromagnetic waves investigated on neuronal hormone levels in rat...
متن کاملCharged Particle in an Electromagnetic Field Using Variational Integrators
In the present work we extend the discrete Lagrangian integrator method presented in Ref. [1] to derive appropriate numerical maps for the solution of mechanical problems in which the potential energy depends on the velocity of the system. As a representative concrete example and simulated experiment of the method presented here, we examine the motion of a charged particle moving in an electrom...
متن کاملSupersymmetry of a spin 12 particle on the real line
We study one dimensional supersymmetric (SUSY) quantum mechanics of a spin 12 particle moving in a rotating magnetic field and scalar potential. We also discuss SUSY breaking and it is shown that SUSY breaking essentially depends on the strength and period of the magnetic field. For a purely rotating magnetic field the eigenvalue problem is solved exactly and two band energy spectrum is found.
متن کاملCharacterizing the entanglement of symmetric many - particle spin - 12 systems
Analyzing the properties of entanglement in many-particle spin-1/2 systems is generally difficult because the system’s Hilbert space grows exponentially with the number of constituent particles, N. Fortunately, it is still possible to investigate a many-particle entanglement when the state of the system possesses sufficient symmetry. In this paper, we present a practical method for efficiently ...
