Spin-induced and orbital quantum backflow in Pauli theory
Tomasz Radożycki
We show that quantum backflow in spin- systems within the Pauli framework can arise from spin-dependent contributions to the probability current. We construct explici…
Polarization-controlled optical backflow in paraxial electromagnetic beams
Tomasz Radożycki
Optical backflow in paraxial Gaussian beams is investigated within the Maxwell framework. Scalar potential representations are employed to identify conditions under which the longi…
Two mechanisms of backward optical forces on Rayleigh particles in structured paraxial light
Tomasz Radożycki
A theoretical and numerical study of optical forces acting on a Rayleigh particle in a paraxial Gaussian light beam exhibiting regions of optical backflow is presented. Within the…
Guiding neutral particles endowed with a magnetic moment by an electromagnetic wave carrying orbital angular momentum. II. Quantum mechanics
Tomasz Radożycki
The quantum mechanical states of the neutral particle endowed with a magnetic moment in the combination of electromagnetic vortex field together with the constant magnetic field ar…
Trapping neutral particles endowed with a magnetic moment by an electromagnetic wave carrying orbital angular momentum: Semiclassical theory
Iwo Bialynicki-Birula, Tomasz Radożycki
The motion of a neutral atom endowed with a magnetic moment interacting with the magnetic field is determined from the Ehrenfest-like equations of motion. These equations for the a…
