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…
Light-Driven Transitions in Quantum Paraelectrics
Zekun Zhuang, Ahana Chakraborty, Premala Chandra +2
Motivated by recent experiments on pump-induced polar ordering in the quantum paraelectric SrTiO, we study a driven phonon system close to a second order phase transition. Anal…
Transport in honeycomb lattice with random -fluxes: implications for low-temperature thermal transport in the Kitaev spin liquids
Zekun Zhuang
Motivated by the thermal transport problem in the Kitaev spin liquids, we consider a nearest-neighbor tight-binding model on the honeycomb lattice in the presence of random uncorre…
Spin Transport in Quantum Spin-Orbital Liquids
Zekun Zhuang, J. B. Marston
Quantum spin-orbital liquids (QSOLs) are a novel phase of matter, similar to quantum spin liquids, with quantum fluctuations in both spin and orbital degrees of freedom. We use non…
Resistively detected NMR as a probe of the topological nature of conducting edge/surface states
Zekun Zhuang, V. F. Mitrović, J. B. Marston
Electron spins in edge or surface modes of topological insulators (TIs) with strong spin-orbit coupling cannot be directly manipulated with microwaves due to the locking of electro…
Transport in Conductors and Rectifiers: Mean-Field Redfield Equations and Non-Equilibrium Green's Functions
Zekun Zhuang, Jaime Merino, J. B. Marston
We derive a closed equation of motion for the one particle density matrix of a quantum system coupled to multiple baths using the Redfield master equation combined with a mean-fiel…
