Methods to Test the Source of the Extreme Gas Motions in WS 35
We present theoretical arguments toward the plausibility of a stellar wind}to explain the 16000\,km\,$s^{-1}$ line broadening in the optical spectra of WS 35, the central star in the Pa 30 nebula. The wind model is discussed in the context of super-Eddington flows. We argue that WS 35 potentially occupies a new regime of wind driving theory as the first metal-only wind. While this framework provides a promising avenue for explaining the high speed flow, questions remain about the source's true …

🚂Coming to Vancouver Island this summer? Headed to Tofino!? Make a stop for a train ride in Port Alberni! 🚂
Every weekend will have rides using a restored diesel loco and heritage passenger cars on the waterfront.
4 weekends will feature the 95yr old No7 Steam Locomotive!

Estimation of Exciton Binding Energy and lifetime for Mono-layer Transition Metal Dichalcogenides
In this work, we present a mathematical model for the Wannier-Mott exciton in monolayers of transition metal dichalcogenides such as $WS_2$, $WSe_2$, $MoS_2$, $MoSe_2$ that estimates the radiation lifetime in the effective mass approximation. We calculate exciton energy, and binding energy by solving the Schrodinger wave equation with open boundary conditions to obtain quasi-bound states in the confined direction in the monolayer and decay rates by the Fermi-Golden rule. The proposed model uses…

Ontario to give education minister power to more easily take over school boards - because as we all know Centralization is the Future because everyone already knows absolutely everything is already monitored and directed by a very busy single old bearded man living somewhere in heaven¹, so the method must be sound? #BurlingtonNews

AC-Stark Spectroscopy of Interactions between Moiré Excitons and Polarons
We use nonlinear pump-probe spectroscopy to study optical excitations in a charge-tunable MoSe$_2$\WS$_2$ moiré heterostructure. An intense red-detuned laser pulse creates a photonic dressing of the material by introducing a large virtual population of excitons or exciton polarons in a deep moiré potential. By measuring the resulting ac Stark effect with a weak resonant laser pulse, we gain access to the nature and mutual interactions of the elementary optical excitations. At charge neutralit…
