Quantum phase diagram and chiral spin liquid in the extended spin- honeycomb XY model
Yixuan Huang, Xiao-Yu Dong, D. N. Sheng +1
The frustrated XY model on the honeycomb lattice has drawn lots of attentions because of the potential emergence of chiral spin liquid (CSL) with the increasing of frustrations or…
Higher-order Dirac fermions in three dimensions
Weikang Wu, Zhi-Ming Yu, Xiaoting Zhou +2
Relativistic massless Weyl and Dirac fermions exhibit the isotropic and linear dispersion relations to preserve the Poincaré symmetry, the most fundamental symmetry in high energy…
Spin-1 Kitaev-Heisenberg model on a two-dimensional honeycomb lattice
Xiao-Yu Dong, D. N. Sheng
We study the Kitaev-Heisenberg model with spin-1 local degree of freedom on a two-dimensional honeycomb lattice numerically by density matrix renormalization group method. By tunin…
High-resolution spectropolarimetric observations of the temporal evolution of magnetic fields in photospheric bright points
Peter H. Keys, Aaron Reid, Mihalis Mathioudakis +7
Context. Magnetic bright points (MBPs) are dynamic, small-scale magnetic elements often found with field strengths of the order of a kilogauss within intergranular lanes in the pho…
Phonon-induced Floquet second-order topological phases protected by space-time symmetries
Swati Chaudhary, Arbel Haim, Yang Peng +1
The co-existence of spatial and non-spatial symmetries together with appropriate commutation/anticommutation relations between them can give rise to static higher-order topological…
Comparison of the Scaling Properties of EUV Intensity Fluctuations in Coronal Hole and Quiet-Sun Regions
Ana Cristina Cadavid, Mari Paz Miralles, Kristine Romich
Using detrended fluctuation analysis (DFA) and rescaled range (R/S) analysis, we investigate the scaling properties of EUV intensity fluctuations of low-latitude coronal holes (CHs…
