Tunable Skyrmions in a Topological Wigner Crystal
David A. Dahlbom, Daniel Kaplan, Premala Chandra +1
In low density systems with strong interactions electrons are expected to crystallize into a Wigner solid. Recently, advances in two-dimensional systems where electrons carry Berry…
Optically-Induced Faraday-Goldstone Waves
Daniel Kaplan, Pavel A. Volkov, Andrea Cavalleri +1
Faraday waves, typically observed in driven fluids, result from the confluence of nonlinearity and parametric amplification. Here we show that optical pulses can generate analogous…
Spatiotemporal Order and Parametric Instabilities from First-Principles
Daniel Kaplan, Pavel A. Volkov, Jennifer Coulter +2
Shaping crystal structure with light is an enduring goal of physics and materials engineering. Here we present calculations in candidate materials selected by symmetry that allow l…
Tunable Spatiotemporal Orders in Driven Insulators
Daniel Kaplan, Pavel A. Volkov, Ahana Chakraborty +2
We show that driving optical phonons above a threshold fluence induces spatiotemporal orders, where material properties oscillate at an incommensurate wavevector in space and…
