Phase diagram of the extended chequerboard model
Jiayou Yin, Lu Liu
The chequerboard model was proposed to describe the direct phase transition from the antiferromagnetic (AFM) state to the plaquette-sin glet (PS) solid state observed in SrCu…
Structure-Preserving Dynamic Mode Decomposition for Highly Oscillatory Dynamics of Semiclassical Schrödinger Equations
Yizhe Feng, Weiguo Gao, Jia Yin
We propose two novel data-driven dynamic mode decomposition (DMD)-type methods, the Crank--Nicolson DMD and the semi-implicit DMD, to predict the highly oscillatory dynamics of the…
GPU acceleration of non-equilibrium Green's function calculation using OpenACC and CUDA FORTRAN
Jia Yin, Khaled Z. Ibrahim, Mauro Del Ben +3
The numerical solution of the Kadanoff-Baym nonlinear integro-differential equations, which yields the non-equilibrium Green's functions (NEGFs) of quantum many-body systems, poses…
Predicting nonequilibrium Green's function dynamics and photoemission spectra via nonlinear integral operator learning
Yuanran Zhu, Jia Yin, Cian C. Reeves +2
Understanding the dynamics of nonequilibrium quantum many-body systems is an important research topic in a wide range of fields across condensed matter physics, quantum optics, and…
