Lightning Calculations With Light*

LOFAR Lightning Imaging; Mapping Lightning with Nanosecond Precision

Lightning mapping technology has proven instrumental in understanding lightning. In this work we present a pipeline that can use lightning observed by the LOw-Frequency ARray (LOFAR) radio telescope to construct a 3D map of the flash. We show that LOFAR has unparalleled precision, on the order of meters, even for lightning flashes that are over 20 km outside the area enclosed by LOFAR antennas ...

Quantum Monte Carlo Calculations for Light Nuclei

Quantum Monte Carlo calculationsof ground and low-lying excited states for nuclei with A 8 are made using a realistic Hamiltonian that ts NN scattering data. Results for more than 40 diierent (J ; T) states, plus isobaric analogs, are obtained and the known excitation spectra are reproduced reasonably well. Various density and momentum distributions and electromagnetic form factors and moments ...

Faddeev - Yakubovsky calculations for light ΛΛ hypernuclei

New Faddeev-Yakubovsky calculations are reported for 6 ΛΛ He and 10 ΛΛ Be in terms of clusters of α's and Λ's, using ΛΛ s-wave potentials motivated by several of the Nijmegen model interactions. The self consistency of the ΛΛ hypernuclear world data for these species is discussed. The newly reported 6 ΛΛ He event is found to be compatible with ΛΛ interaction strengths provided by the Nijmegen s...

Quantum Monte Carlo Calculations of Light Nuclei

The goal of ab-initio light-nuclei calculations is to understand nuclei as collections of nucleons interacting with realistic (bare) potentials through reliable solutions of the many-nucleon Schrödinger equation. Such calculations can study binding energies, excitation spectra, relative stability, densities, transition amplitudes, cluster-cluster overlaps, low-energy astrophysical reactions, an...
