Robust topological oscillators govern a tunable phase transition to synchronized circadian rhythms
Chongbin Zheng, Peter Thomas, Evelyn Tang
The paper proposes a mechanism by which stochastic circadian KaiC proteins, which follow topologically protected cycles, can synchronize through a phase transition that depends on…
Topological edge currents promote exploratory chromosome capture in microtubule dynamic instability
Chongbin Zheng, Jaime Agudo-Canalejo, Jonathon Howard +1
Microtubules capture chromosomes during mitosis by stochastically switching between growth and shrinkage at catastrophe events. They display strikingly rich biochemistry and dynami…
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…
Analytical topological invariants for 2D non-Hermitian phases using Morse theory
Cameron Gibson, Evelyn Tang
As energy dissipation and gain are ubiquitous in the real world, such phenomena demand the generalization of Hermitian methods such as the analysis of topological properties for no…
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 phases in discrete stochastic systems
Jaime Agudo-Canalejo, Evelyn Tang
Topological invariants have proved useful for analyzing emergent function as they characterize a property of the entire system, and are insensitive to local details, disorder, and…
