Volcano-Like Ferroic Transitions Deviating from the Model of Landau Theory
Yuxuan Sheng, Menghao Wu
We predict the existence of abnormal volcano-like temperature dependence of polarization or magnetization with maxima located at elevated temperature, distinct from classical model…

Ubiquitous van der Waals altermagnetism with sliding/moire ferroelectricity
Yuxuan Sheng, Junwei Liu, Jia Zhang +1
According to the recent studies on sliding/moire ferroelectricity, most 2D van der Waals nonferroelectric monolayers can become ferroelectric via multilayer stacking. In this paper…

Ferroelectricity in crystals with non-polar point groups
Yuxuan Sheng, Menghao Wu
Ferroelectric crystals must adopt one of the 10 polar point groups according to the Neumann's principle. In this paper we propose that this conclusion is based on perfect bulk crys…
