Potential-tuned magnetic switches and half-metallicity transition in zigzag graphene nanoribbons
Wei-Jian Li, Shi-Chang Xiao, Da-Fei Sun +3
Realizing controllable room-temperature ferromagnetism in carbon-based materials is one of recent prospects. The magnetism in graphene nanostructures reported previously is mostly…
Topological states in a dimerized system with staggered magnetic fluxes
Ai-Lei He, Wei-Wei Luo, Yuan Zhou +2
The bulk-boundary correspondence is a generic feature of topological states of matter, reflecting the intrinsic relation between topological bulk and boundary states. For example,…
Bosonic fractional Chern insulating state at integer fillings in multi-band system
Wei-Wei Luo, Ai-Lei He, Yi-Fei Wang +2
The integer quantum Hall state occurs when the Landau levels are fully occupied by the fermions, while the fractional quantum Hall state usually emerges when the Landau level is pa…
Quasicrystalline Chern Insulators
Ai-Lei He, Lu-Rong Ding, Yuan Zhou +2
Chern insulator or quantum anomalous Hall state is a topological state with integer Hall conductivity but in absence of Landau level. It had been well established on various two-di…
Variational Monte Carlo study of spin dynamics in underdoped cuprates
Zuo-Dong Yu, Yuan Zhou, Chang-De Gong
The hour-glass-like dispersion of spin excitations is a common feature of underdoped cuprates. It was qualitatively explained by the random phase approximation based on various ord…
Characterizations of topological superconductors: Chern numbers, edge states and Majorana zero modes
Xiao-Ping Liu, Yuan Zhou, Yi-Fei Wang +1
The topological properties in topological superconductors are usually characterized by the bulk Chern numbers, edge-state spectra, and Majorana zero modes. Whether they are equival…
Width-tuned magnetic order oscillation on zigzag edges of honeycomb nanoribbons
Wen-Chao Chen, Yuan Zhou, Shun-Li Yu +2
Quantum confinement and interference often generate exotic properties in nanostructures. One recent highlight is the experimental indication of a magnetic phase transition in zigza…
Phase Competition and Anomalous Thermal Evolution in High-Temperature Superconductors
Zuo-Dong Yu, Yuan Zhou, Wei-Guo Yin +2
The interplay of competing orders is relevant to high-temperature superconductivity known to emerge upon suppression of a parent antiferromagnetic order typically via charge doping…
Dipolar phonons and electronic screening in monolayer FeSe on SrTiO
Yuanjun Zhou, Andrew J. Millis
Monolayer films of FeSe grown on SrTiO substrates exhibit significantly higher superconducting transition temperatures than those of bulk FeSe. Interaction of electrons in the…
Charge transfer and electron-phonon coupling in monolayer FeSe on Nb doped SrTiO
Yuanjun Zhou, Andrew J. Millis
Monolayer films of FeSe grown on SrTiO substrates are electron doped relative to bulk and exhibit a significantly higher superconducting transition temperatures. We present den…
Surface polarization and edge charges
Yuanjun Zhou, Karin Rabe, David Vanderbilt
The term "surface polarization" is introduced to describe the in-plane polarization existing at the surface of an insulating crystal when the in-plane surface inversion symmetry is…
Coupled nonpolar-polar metal-insulator transition in 1:1 SrCrO/SrTiO superlattices: A first-principles study
Yuanjun Zhou, Karin M. Rabe
Using first principles calculations, we determined the epitaxial-strain dependence of the ground state of the 1:1 SrCrO/SrTiO superlattice. The superlattice layering leads…

Yuanjun Zhou, Karin M. Rabe
In the development of first-principles high-throughput searches for materials with desirable functional properties, there is a clear need for an efficient method to determine the g…
Resonance, Fermi surface topology, and Superconductivity in Cuprates
Yuan Zhou, Haiyang Zhang, Haiqing Lin +1
The resonance, a collective boson mode, was usually thought to be a possible glue of superconductivity. We argue that it is rather a natural product of the \emph{d}-wave pairing an…
