Success and breakdown of the T-matrix approximation for phonon-disorder scattering
S. Thébaud, C. A. Polanco, L. Lindsay +1
We examine the validity of the widely used T-matrix approximation for treating phonon-disorder scattering by implementing an unfolding algorithm that allows simulation of disorder…

Space-time dependent thermal conductivity in nonlocal thermal transport
Chengyun Hua, Lucas Lindsay
Nonlocal thermal transport is generally described by the Peierls-Boltzmann transport equation (PBE). However, solving the PBE for a general space-time dependent problem remains a c…

Phonons, Q-dependent Kondo spin fluctuations, and 4/phonon resonance in YbAl
Andrew D. Christianson, Victor R. Fanelli, Lucas Lindsay +7
The intermediate valence (IV) compound YbAl exhibits nonintegral valence (Yb 4 (5d6s) where z = 2+n = 2.75) in a moderately heavy (m* = 20-30me) ground stat…
