Worldvolume Hybrid Monte Carlo algorithm for group manifolds
The Worldvolume Hybrid Monte Carlo (WV-HMC) method [arXiv:2012.08468] is a reliable and versatile algorithm for addressing the sign problem. It resolves the ergodicity issues commonly encountered in Lefschetz thimble-based approaches at a low computational cost. In this article, as a first step toward applying WV-HMC to lattice QCD, we extend the algorithm to cases where the configuration space is a group manifold. The key idea is to formulate the algorithm using a phase-space integral over the…

Biexciton-polariton coupling mediated by dark states
Multi-exciton correlations shape the photo-induced response of nanostructured materials, particularly when interactions are enhanced by light confinement. Here multidimensional coherent spectroscopy is used to quantify biexciton and exciton-polariton dynamics in a semiconductor microcavity. One- and two-quantum spectra, which are dominated by polariton-related contributions, also include a polarization-dependent biexciton feature whose magnitude and spectral coordinates depend on the detuning b…

First night of my Southern #MotoCamping trip. Camped right on the shore of the Kanawa River just outside of Point Pleasant, WV. Tomorrow morning after breaking camp I'll head into town to visit the #mothman statue and museum, then on to the Red River Gorge.

Getting packed for a week long motorcycle camping trip. I leave tomorrow. This is a much much needed break.
First night I'll be camping in Point Pleasant, WV and visiting the Mothman museum. After that, heading over to the Red River Gorge in Kentucky, then looping down through Tennessee, North Carolina and back into West Virginia where I'm planning to spend a couple of days exploring sites like Audra State Park and Blackwater Falls. I'll be posting photos from the trip here…
