Temperature-dependent anharmonic phonons in quantum paraelectric KTaO by first principles and machine-learned force fields
Luigi Ranalli, Carla Verdi, Lorenzo Monacelli +3
Understanding collective phenomena in quantum materials from first principles is a promising route toward engineering materials properties on demand and designing new functionaliti…
Thermal transport and phase transitions of zirconia by on-the-fly machine-learned interatomic potentials
Carla Verdi, Ferenc Karsai, Peitao Liu +2
Machine-learned interatomic potentials enable realistic finite temperature calculations of complex materials properties with first-principles accuracy. It is not yet clear, however…
Optical and excitonic properties of transition metal oxide perovskites by the Bethe-Salpeter equation
Lorenzo Varrassi, Peitao Liu, Zeynep Ergönenc Yavas +3
We present a systematic investigation of the role and importance of excitonic effects on the optical properties of transitions metal oxide perovskites. A representative set of four…
Electronic state unfolding for plane waves: energy bands, Fermi surfaces and spectral functions
David Dirnberger, Georg Kresse, Cesare Franchini +1
Modern computing facilities grant access to first-principles density-functional theory study of complex physical and chemical phenomena in materials, that require large supercell t…
- phase transition of zirconium predicted by on-the-fly machine-learned force field
Peitao Liu, Carla Verdi, Ferenc Karsai +1
The accurate prediction of solid-solid structural phase transitions at finite temperature is a challenging task, since the dynamics is so slow that direct simulations of the phase…
Nonrad: Computing Nonradiative Capture Coefficients from First Principles
Mark E. Turiansky, Audrius Alkauskas, Manuel Engel +5
Point defects in semiconductor crystals provide a means for carriers to recombine nonradiatively. This recombination process impacts the performance of devices. We present the Nonr…
