Development of Monte Carlo configuration interaction: Natural orbitals and second-order perturbation theory
J. P. Coe, M. J. Paterson
Approximate natural orbitals are investigated as a way to improve a Monte Carlo configuration interaction (MCCI) calculation. We introduce a way to approximate the natural orbitals…
Tail asymptotics for the supremum of a random walk when the mean is not finite
D. Denisov, S. Foss, D. Korshunov
We consider the sums of independent identically distributed random variables. We do not assume that the 's have a finite mean. Under subexponential type con…
Asymptotics for sums of random variables with local subexponential behaviour
S. Asmussen, S. Foss, D. Korshunov
We study distributions on such that for some , . The case corresponds to being subexponential, and our ana…
Singlet oxygen luminescence detection with a fiber-coupled superconducting nanowire single-photon detector
Nathan R. Gemmell, Aongus McCarthy, Baochang Liu +7
Direct monitoring of singlet oxygen (1O2) luminescence is a particularly challenging infrared photodetection problem. 1O2, an excited state of the oxygen molecule, is a crucial int…
Monte Carlo configuration interaction applied to multipole moments, ionisation energies and electron affinities
J. P. Coe, D. J. Taylor, M. J. Paterson
The method of Monte Carlo configuration interaction (MCCI) [1,2] is applied to the calculation of multipole moments. We look at the ground and excited state dipole moments in carbo…
Enhanced thermoelectric performance in TiNiSn-based half-Heuslers
R. A. Downie, D. A. MacLaren, R. I. Smith +1
Thermoelectric figures of merit, ZT > 0.5, have been obtained in arc-melted TiNiSn-based ingots. This promising conversion efficiency is due to a low lattice thermal conductivity,…
