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…
Real-space imaging of polar and elastic nano-textures in thin films via inversion of diffraction data
Ziming Shao, Noah Schnitzer, Jacob Ruf +13
Exploiting the emerging nanoscale periodicities in epitaxial, single-crystal thin films is an exciting direction in quantum materials science: confinement and periodic distortions…
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…
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…
Large Itinerant Electron Exchange Coupling in the Magnetic Topological Insulator MnBi2Te4
Hari Padmanabhan, Vladimir A. Stoica, Peter Kim +20
Magnetism in topological materials creates phases exhibiting quantized transport phenomena with applications in spintronics and quantum information. The emergence of such phases re…
