Temperature-dependent Multi-well Free-energy Landscape for Phase Transitions: PbTiO3 as a Prototype
Yi Wang, Tiannan Yang, Shun-Li Shang +2
It has been a long challenge to analytically construct the quantitative temperature-dependent multi-well free-energy landscape over the space of order parameters describing phase t…
Landau-Ginzburg theory of charge density wave formation accompanying lattice and electronic long-range ordering
Anna Morozovska, Eugene Eliseev, Venkatraman Gopalan +1
We propose an analytical Landau-Ginzburg theory of the charge density waves coupled with lattice and electronic long-range order parameters. Examples of long-range order include el…
Thermodynamic and electron-transport properties of Ca3Ru2O7 from first-principles phonon calculations and Boltzmann transport theory
Yi Wang, Yihuang Xiong, Tiannan Yang +6
This work demonstrates a first-principles-based approach to obtaining finite temperature thermal and electronic transport properties which can be employed to model and understand m…
Bifurcation Analysis Reveals Solution Structures of Phase Field Models
Xinyue Evelyn Zhao, Long-Qing Chen, Wenrui Hao +1
Phase field method is playing an increasingly important role in understanding and predicting morphological evolution in materials and biological systems. Here, we develop a new ana…
A Solution to the Temperature Evolution of Multi-well Free-energy Landscape
Yi Wang, Tiannan Yang, Shun-Li Shang +2
It has been a grand challenge to resolve the temperature evolution of multi-well free-energy landscape which is fundamentally relevant to phase transitions and associated critical…
Electric-field control of the nucleation and motion of isolated three-fold polar vertices
Mingqiang Li, Tiannan Yang, Pan Chen +12
Recently various topological polar structures have been discovered in oxide thin films. Despite the increasing evidence of their switchability under electrical and/or mechanical fi…
