Quantum Computation of Scattering in Scalar Quantum Field Theories
TL;DR: A quantum algorithm to compute relativistic scattering amplitudes in massive ϕ4 theory in spacetime of four and fewer dimensions offers exponential speedup over existing classical methods at high precision or strong coupling.
Journal ArticleDOI
Long‐Range Scattering from Anisotropic Potentials: Dipole—Dipole Scattering
R. J. Cross,R. G. Gordon +1 more
TL;DR: In this paper, the authors used Born approximation or a semiclassical method based on time-dependent perturbation theory to obtain the scattering matrix for large impact parameters (both methods yield the same results).
Journal ArticleDOI
The influence of paramagnetic molecules on singlet-triplet transitions
TL;DR: In this article, it was shown that singlet-triplet transitions may obtain a finite probability when exchange interaction occurs between the absorbing molecule and a paramagnetic molecule, and no quantitative relation exists between the transition dipole strength and the paramagnetic susceptibility of the perturbing molecule.
Journal ArticleDOI
Estimation of the spontaneous emission factor for microdisk lasers via the approximation of whispering gallery modes
TL;DR: In this paper, a simple, approximate method for solving the waveguide modes and the density of states is developed, using conformal transformation and the Wentzel-Kramers-Brillouin approximation and taking into account the effect of the disk thickness.

Iteration methods for calculating self-consistent fields in semiconductor inversion layers
TL;DR: In this paper, two new methods for attaining convergence in self-consistent field calculations are described, which have been applied to semiconductor inversion layers at finite temperature, and have been shown to achieve a significant improvement in the performance.
