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…
Quantum order by disorder in Frustrated Spin Nanotubes
João C. Getelina, Zekun Zhuang, Premala Chandra +3
We investigate quantum order by disorder in a frustrated spin nanotube formed by wrapping a - Heisenberg model at 45 around a cylinder. Using Schwinger boson theo…
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…
Quantum Szilard engines with arbitrary spin
Zekun Zhuang, Shi-Dong Liang
The quantum Szilard engine (QSZE) is a conceptual quantum engine for understanding the fundamental physics of quantum thermodynamics and information physics. We generalize the QSZE…
