Simulation of the Schrödinger particle non-elastic scattering with emission of photon in the quantum register

Marcin Ostrowski

This paper investigates whether a quantum computer can efficiently simulate the non-elastic scattering of the Schrödinger particle on a stationary excitable shield. The return of the shield to the ground state is caused by photon emission. An algorithm is presented for simulating the time evolution of such a process, implemented on standard two-input gates. The algorithm is used for the computation of elastic and non-elastic scattering probabilities. The results obtained by our algorithm are compared with those obtained using the standard Cayley’s method.

Multimode excitation of stimulated light scattering in spherical particles: the angular characteristics of scattered radiation

Аlexander А. Zemlyanov, Yu. É. Geints, E. K. Chistyakova

We analyze here the influence of multi-mode excitation of stimulated light scattering (SLS) in the spherical particle on the angular intensity distribution in the far-field zone. It is shown that at multi-mode excitation of SLS the scattering diagram becomes asymmetric, unlike the case, when process is realized on single resonant mode of a particle. Degree of its asymmetry significantly depends on combinations of modes excited in the particle that brings either to a significant increase of the intensity of backscattered wave, or to its weakening in the given direction. The comparison with angular intensity distribution at elastic scattering is made.

Spectroscopic properties and cold elastic collisions of alkaline-earth Mg + Mg + system

Nissrin Alharzali, Dibyendu Sardar, Rim Mlika +2 more

Abstract In this theoretical work, we calculate molecular potential energy curves, spectroscopic constants and transition dipole moments for the ground ( X 2 Σ + u , B 2 Σ + g ) and first excited electronic states (A 2 Π u ) of alkaline-earth molecular ion Mg 2 + . We consider an ab initio multi-reference configuration interaction method using an aug-cc-pv5z Gaussian basis set and compare our results with those obtained by others. The comparison shows a very good agreement. In addition, we investigate the ion-atom elastic collisions for a wide range of energies including the isotopic effect. In close connections, we determine the scattering T-matrix elements for ground-state electronic potentials, which show divergent behavior at a particular energy, indicating the occurrence of scattering resonances. We find that the s -wave scattering length is positive for both ground-state potentials. We also study possible free-bound transitions and Franck–Condon overlap for our system.
