LaN Structural and Topological Transitions Driven by Temperature and Pressure
Wei-Chih Chen, Chia-Min Lin, Joseph Maciejko +1
We study lanthanum mononitride LaN by first-principles calculations. The commonly reported rock-salt structure of symmetry for rare-earth monopnictides is found dynami…
Machine Learning and Evolutionary Prediction of Superhard B-C-N Compounds
Wei-Chih Chen, Joanna N. Schmidt, Da Yan +2
We build random forests models to predict elastic properties and mechanical hardness of a compound, using only its chemical formula as input. The model training uses over 10,000 ta…
Lattice frustration in spin-orbit Mott insulator Sr3Ir2O7 at high pressure
Jianbo Zhang, Dayu Yan, Sorb Yesudhas +13
The intertwined charge, spin, orbital, and lattice degrees of freedom could endow 5d compounds with exotic properties. Current interest is focused on electromagnetic interactions i…
Numerical Investigation of Spin Excitations in a Doped Spin Chain
Ekaterina M. Pärschke, Yao Wang, Brian Moritz +3
We study the doping evolution of spin excitations in a 1D Hubbard model and its downfolded spin Hamiltonians, by using exact diagonalization combined with cluster perturbation theo…
Evidence for a strain tuned topological phase transition in ZrTe5
Joshua Mutch, Wei-Chih Chen, Preston Went +5
A phase transition between topologically distinct insulating phases involves closing and reopening of the bandgap. Close to this topological phase transition, the bulk energy spect…
Theory of Time-Resolved Raman Scattering in Correlated Systems: Ultrafast Engineering of Spin Dynamics and Detection of Thermalization
Yao Wang, Thomas P. Devereaux, Cheng-Chien Chen
Ultrafast characterization and control of many-body interactions and elementary excitations are critical to understanding and manipulating emergent phenomena in strongly correlated…
