Thermal disorder and phonon softening in the ferroelectric phase transition of lead titanate
Pinchen Xie, Yixiao Chen, Weinan E +1
We report a molecular dynamics study of ab initio quality of the ferroelectric phase transition in crystalline PbTiO3. We model anharmonicity accurately in terms of potential energ…

Ground state phases of the two-dimension electron gas with a unified variational approach
Conor Smith, Yixiao Chen, Ryan Levy +3
The two-dimensional electron gas (2DEG) is a fundamental model, which is drawing increasing interest because of recent advances in experimental and theoretical studies of 2D materi…
