Spectra-orthogonal optical anisotropy in wafer-scale molecular crystal monolayers

Kavli Affiliate: David A. Muller | First 5 Authors: Tomojit Chowdhury, Fauzia Mujid, Zehra Naqvi, Ariana Ray, Ce Liang | Summary: Controlling the spectral and polarization responses of two-dimensional (2D) crystals is vital for developing ultra-thin platforms for compact optoelectronic devices. However, independently tuning optical anisotropy and spectral response remains challenging in conventional semiconductors due […]

Rigorous expansions of modular forms at CM points, I: Denominators

Kavli Affiliate: Chris Xu | First 5 Authors: Chris Xu, , , , | Summary: We describe an algorithm to rigorously compute the power series expansion at a CM point of a weight $2$ cusp form of level coprime to $6$. Our algorithm works by bounding the denominators that appear due to ramification, and without […]

Reactive path ensembles within nonequilibrium steady-states

Kavli Affiliate: David T. Limmer | First 5 Authors: Aditya N. Singh, David T. Limmer, , , | Summary: The modern theory of rare events is grounded in near equilibrium ideas, however many systems of modern interest are sufficiently far from equilibrium that traditional approaches do not apply. Using the recently developed variational path sampling […]
