A quantum analogy to the classical gravitomagnetic clock effect
We present an approximation to the solution of Dirac equation in Schwarzschild field found through the use of Foldy-Wouthuysen Hamiltonian. We solve the equation for the positive energy states and found the frequencies by which the states oscillate ...

Analysis of rescattering effects in $$3\pi $$ 3 π final states
Decays into three particles are often described in terms of two-body resonances and a non-interacting spectator particle. To go beyond this simplest isobar model, crossed-channel rescattering effects need to be accounted for.

Partons as unique ground states of quantum Hall parent Hamiltonians: The case of Fibonacci anyons
We present microscopic, multiple Landau level, (frustration-free and positive semi-definite) parent Hamiltonians whose ground states, realizing different quantum Hall fluids, are parton-like and whose excitations display either Abelian or non-Abelian ...

Can the radial number of vortex modes control the orbital angular momentum?
In general, a standard Laguerre–Gauss (LG) beam, whose state is given by two quantum numbers (n, 𝓁): the radial number n and the azimuthal number 𝓁 (or the topological charge (TС) of the vortex carried by the LG beam), is unstable with respect to weak ...

Can We Break the Landauer Bound in Spin-Based Electronics?
We found that the minimum energy of reading or erasing a spin datum should be expressed by $\Delta E=2~\mu _{B}B$ , in contrast to ${\Delta E=k}_{B}T\,\,ln(2)$ proposed by Landauer in 1961. The physics of using a spin’s orientation to represent

Signature and Angular Momentum in 3d-Cranked HFB states [PDF]
In terms of the exaxt angular momentum projection, properties of the three dimensional cranked HFB (3d-CHFB) states are analyzed quantitatively in the context of the relation between the signature of an intrinsic symmetry and the parity of angular ...

Photon vortex generation by synchrotron radiation experiments in relativistic quantum approach
We formulate a theoretical approach to describe photon vortex production in synchrotron/cyclotron radiation from a helical moving electron under a uniform magnetic field in the relativistic quantum framework.

Probability of radiation of twisted photons by classical currents [PDF]
The general formula for the probability of radiation of a twisted photon by a classical current is derived. The general theory of generation of twisted photons by undulators is developed.

Self-Energy Correction to the Hyperfine Splitting for Excited States [PDF]
The self-energy corrections to the hyperfine splitting is evaluated for higher excited states in hydrogenlike ions, using an expansion in the binding parameter Zalpha, where Z is the nuclear charge number, and alpha is the fine-structure constant.

Multidimensional QKD Based on Combined Orbital and Spin Angular Momenta of Photon
It has been widely recognized that the underlying principles of quantum mechanics could be used to enable secure communications, without any additional conventional cryptographic systems, while utilizing the properties of the photons.
