The advancement of high-power and short-pulse laser technology in the past two decades
has generated considerable interest in the study of multiphoton and very high-order …

Electron-impact ionization of the hydrogen atom is the prototypical three-body Coulomb
breakup problem in quantum mechanics. The combination of subtle correlation effects and …

We show how the finite-element method can be implemented using a discrete variable
representation to provide an efficient means for directly solving the time-independent …

The past decade has seen extraordinary theoretical progress in the field of fully
kinematically resolved atomic electron-impact ionisation, and its closely related field of …

The first three electronically excited states in the alkaline-earth-metal atoms magnesium,
calcium, and strontium comprise the (nsnp) PJ o 3 (J= 0, 1, 2) fine-structure manifold. All …

The derivation of the transformative complex absorbing potential (TCAP) method and its
performance are discussed. This approach was developed in a previous paper (1995 J …

We calculate the mass spectrum of the Q sq¯ q¯(Q= c, b) tetraquark states with JP=(0, 1, 2)+
using the AL1 quark potential model, which successfully describes the conventional hadron …

We present a robust, ab initio method for addressing atom-light interactions and apply it to
photoionization of argon. We use a close-coupling ansatz constructed on a …

B-spline methods are now well established as widely applicable tools for the evaluation of
atomic and molecular continuum states. The mathematical technique of exterior complex …

Exterior complex scaling enables one to solve the time-independent Schrödinger equation
for three charged particles without explicitly imposing the asymptotic boundary condition for …
