Complete numerical solution of bohr's collective hamiltonian.
Krishna Kumar,Michel Baranger +1 more
TL;DR: In this article, a purely numerical method involving a finite mesh is developed for solving the Schrodinger equation for quadrupole deformations, which is tested on a number of examples and is found to be sufficiently accurate for application to spherical, transition and many deformed nuclei.

Suppression of bremsstrahlung and pair production due to environmental factors
TL;DR: In this article, the authors discuss the Landau-Pomeranchuk-Migdal effect and a variety of other factors that can suppress bremsstrahlung and pair production.

On the time operator in quantum mechanics and the heisenberg uncertainty relation for energy and time
TL;DR: In this paper, it was shown that for a given 3-dimensional hyperplane Q, generated by two space-like and one time-like vector, one can construct three operators: x1Q, x2Q, tQ. The operator tQ is used to formulate the realistic interpretation of the uncertainty relation Δt · ΔE ⩾ ħ/2.

Calculation of first and second static hyperpolarizabilities of one- to three-dimensional periodic compounds. Implementation in the CRYSTAL code.
TL;DR: CPHF is applied for beta and gamma of LiF in different aggregation states: finite and infinite chains, slabs, and cubic crystal, with a dependence on the computational parameters similar to that observed for field-free self-consistent field (SCF) calculations.

Laser oscillation from quantum states in very thin GaAs−Al0.2Ga0.8As multilayer structures
TL;DR: In this article, optically pumped laser oscillation from multilayer heterostructures consisting of alternating layers of GaAs and Al0.2Ga0.8As was reported.
