Symmetry-protected trivial phases and quantum phase transitions in an anisotropic antiferromagnetic spin-1 biquadratic model

Xi-Hao Chen, Ian McCulloch, Murray T. Batchelor +1

The ground state phase diagram is obtained for an antiferromagnetic spin-1 anisotropic biquadratic model. With the help of symmetry and duality transformations, three symmetry-prot…

Systematic Regularity of Solar Coronal Rotation During the Time Interval 1939-2019

L. H. Deng, X. J. Zhang, H. Deng +2

Temporal variation of the solar coronal rotation appears to be very complex and its relevances to the eleven-year solar activity cycle are still unclear. Using the modified coronal…

Phase and amplitude asymmetry in the quasi-biennial oscillation of solar Halpha flare activity

L. H. Deng, X. J. Zhang, G. Y. Li +2

Quasi-biennial oscillation (QBO) of solar magnetic activities is intrinsic to dynamo mechanism, but still far from fully understood. In this work, the phase and amplitude asymmetry…

Spatial Distributions of Sunspot Oscillation Modes at Different Temperatures

Zhengkai Wang, Song Feng, Linhua Deng +1

Three- and five-minute oscillations of sunspots have different spatial distributions in the solar atmospheric layers. The spatial distributions are crucial to reveal the physical o…

A class of Randers metrics of scalar flag curvature

Xinyue Cheng, Li Yin, Tingting Li

One of the most important problems in Finsler geometry is to classify Finsler metrics of scalar flag curvature. In this paper, we study the classification problem of Randers metric…
