Analysis and Optimization of Resonance Energies and Widths Using Complex Absorbing Potentials
Jerryman A. Gyamfi, Thomas -C. Jagau
Complex absorbing potentials (CAPs) are artificial potentials added to electronic Hamiltonians to make the wavefunction of metastable electronic states square-integrable. This make…
Semiclassical Quantum Markovian Master Equations. Case Study: Continuous Wave Magnetic Resonance of Multispin Systems
Jerryman A. Gyamfi
We propose a method for deriving Lindblad-like master equations when the environment/reservoir is consigned to a classical description. As a proof of concept, we apply the method t…
Fundamentals of Quantum Mechanics in Liouville Space
Jerryman A. Gyamfi
The purpose of this paper is to articulate a coherent and easy-to-understand way of doing quantum mechanics in any finite-dimensional Liouville space, based on the use of Kronecker…
An Introduction to the Holstein-Primakoff Transformation, with Applications in Magnetic Resonance
J. A. Gyamfi
We have witnessed an impressive advancement in computer performance in the last couple of decades. One would therefore expect a trickling down of the benefits of this technological…
Magnetic Resonance, Index Compression Maps and the Holstein-Primakoff Bosons: Towards a Polynomially Scaling Exact Diagonalization of Isotropic Multispin Hamiltonians
J. A. Gyamfi, V. Barone
Matrix diagonalization has long been a setback in the numerical simulation of the magnetic resonance spectra of multispin systems since the dimension of the Hilbert space of such s…
On the composition of an arbitrary collection of spins: An Enumerative Combinatoric Approach
Jerryman Appiahene Gyamfi, Vincenzo Barone
The whole enterprise of spin compositions can be recast as simple enumerative combinatoric problems. We show here that enumerative combinatorics (EC)\citep{book:Stanley-2011} is a…
