Collimation of diamagnetic laser-driven plasma outflows by an ambient magnetic-pressure gradient
Yigeng Tian, Chung Hei Leung, Arijit Bose +3
We present magnetohydrodynamic simulations of laser driven plasma outflows propagating along an externally applied poloidal magnetic field, designed to mimic coronal open-field pla…
Topology of the simplest gene switch
Aleksandra Nelson, Peter Wolynes, Evelyn Tang
Complex gene regulatory networks often display emergent simple behavior. Sometimes this simplicity can be traced to a nearly equivalent energy landscape, but not always. Here, we s…
Topological edge flows drive macroscopic re-organization in magnetic colloids
Aleksandra Nelson, Dana M. Lobmeyer, Sibani L. Biswal +1
Magnetic colloids can be driven with time-varying fields to form clusters and voids that re-organize over vastly different timescales. However, the driving force behind these non-e…
Non-reciprocity is necessary for robust dimensional reduction and strong responses in stochastic topological systems
Aleksandra Nelson, Evelyn Tang
Topological theory predicts the necessary conditions for robust dimensional reduction in a host of quantum and classical systems. Models have recently been proposed for stochastic…
