It is shown that the atom-molecule collision problem in the presence of an external electric field can be solved using the total angular momentum representation in the body-fixed coordinated frame, le...
The permanent electric dipole moment (EDM) of the ground state of potassium has been found by measuring the electric susceptibility. We find dK=[1.58±0.19(stat)±0.13(syst)]×10-8e.cm and the induced ED...
We study the Wigner functions of the nucleon which provide multidimensional images of the quark distributions in phase space. These functions can be obtained through a Fourier transform in the transve...
We experimentally study the behavior of orbital angular momentum (OAM) of light in a noncollinear second harmonic generation (SHG) process. The experiment is performed by using a type I BBO crystal un...
An efficient method for exploring the orbital angular momentum of an optical vortex beam is provided.The method, based on a triangular multipoint plate, can easily determine both the sign and the magn...
The electronic states in the monolayer graphene with the short-range perturbation asymmetric with respect to the band index are analized. The study was made for the separable in the angular momentum ...
We present measurements of the angular momentum ux (torque) in Taylor-Couette ow of water between independently rotating cylinders for all regions of the (1;2) parameter space at high Reynolds numbe...
We present measurements of the angular momentum flux (torque) in Taylor-Couette flow of water between independently rotating cylinders for all regions of the $\(\Omega_1, \Omega_2\)$ parameter space ...
Based on the vectorial Debye theory, we in-vestigate the tight focusing of elliptically polarized light beams by high numerical-aperture (NA) phase Fresnel zone plates (FZP). The conversion of the sp...
The orbital angular momentum (OAM) of light, associated with a helical structure of the wavefunction, has a great potential for quantum photonics, as it allows attaching a higher dimensional quantum s...
We study the quantum-classical correspondence in terms of coherent wave functions of a charged particle in two-dimensional central-scalar-potentials as well as the gauge field of a magnetic flux in t...
The far- fi eld diffraction pattern of an elliptical vortex beam by a slit hexagon aperture is investigated theoretically and experimentally. It is found that the number of the dark spots or stripes i...
The evolution of an entangled photon state propagating through a turbulent atmosphere is formulated in terms of a set of coupled first order differential equations, by using an infinitesimal propagati...
