The generalized quasiharmonic approximation via space group irreducible derivatives
Mark A. Mathis, Amey Khanolkar, Lyuwen Fu +9
The quasiharmonic approximation (QHA) is the simplest nontrivial approximation for interacting phonons under constant pressure, bringing the effects of anharmonicity into temperatu…
Validating First-Principles Phonon Lifetimes via Inelastic Neutron Scattering
Enda Xiao, Hao Ma, Matthew S. Bryan +10
Phonon lifetimes are a key component of quasiparticle theories of transport, yet first-principles lifetimes are rarely directly compared to inelastic neutron scattering (INS) resul…
Magnetic, transport, and thermal properties of -phase UZr
Xiaxin Ding, Tiankai Yao, Lyuwen Fu +7
Alloys of hexagonal -phase UZr have been synthesized and studied by means of heat capacity, magnetic susceptibility, magnetization, electrical resistivity, magnetoresistance…
A group theoretical approach to computing phonons and their interactions
Lyuwen Fu, Mordechai Kornbluth, Zhengqian Cheng +1
Here we present four independent advances which facilitate the computation of phonons and their interactions from first-principles. First, we implement a group-theoretical approach…
Uniaxial Strain Tuning of Superconductivity in 2-NbSe
Andrew Wieteska, Ben Foutty, Zurab Guguchia +7
We explore the effect of lattice anisotropy on the charge-ordered superconductor 2H-NbSe. Using a novel strain apparatus, we measure the superconducting transition temperatur…
