Electron-phonon physics from first principles using the EPW code
Hyungjun Lee, Samuel Poncé, Kyle Bushick +13
EPW is an open-source software for calculations of electron-phonon interactions and related materials properties. The code combines density functional perturba…
Ab initio self-consistent many-body theory of polarons at all couplings
Jon Lafuente-Bartolome, Chao Lian, Weng Hong Sio +3
We present a theoretical framework to describe polarons from first principles within a many-body Green's function formalism. Starting from a general electron-phonon Hamiltonian, we…
Unified approach to polarons and phonon-induced band structure renormalization
Jon Lafuente-Bartolome, Chao Lian, Weng Hong Sio +3
Ab initio calculations of the phonon-induced band structure renormalization are currently based on the perturbative Allen-Heine theory and its many-body generalizations. These appr…
Neutralization of low energy Na scattered from InAs(001)
Haoshan Zhu, Chao Lian, Bryan M. Wong +1
The neutralization probability of low energy Na ions scattered from In- and As-rich InAs(001) surfaces is measured by time-of-flight spectroscopy. It is found that the neutra…
Indirect but Efficient: Laser-Excited Electrons Can Drive Ultrafast Polarization Switching in Ferroelectric Materials
Chao Lian, Zulfikhar A. Ali, Hyuna Kwon +1
To enhance the efficiency of next-generation ferroelectric (FE) electronic devices, new techniques for controlling ferroelectric polarization switching are required. While most pri…
Ultrafast carrier relaxation and its Pauli drag in photo-enhanced melting of solids
Chao Lian, S. B. Zhang, Sheng Meng
Ultrafast light-matter interaction is a powerful tool for the study of solids. Upon laser excitation, carrier multiplication and lattice acceleration beyond thermal velocity can oc…
