Thermal Energy Transport in Oxide Nuclear Fuel
David H. Hurley, Anter El-Azab, Matthew S. Bryan +13
To efficiently capture the energy of the nuclear bond, advanced nuclear reactor concepts seek solid fuels that must withstand unprecedented temperature and radiation extremes. In t…
High Phonon Scattering Rates Suppress Thermal Conductivity in Hyperstoichiometric Uranium Dioxide
Hao Ma, Matthew S. Bryan, Judy W. L. Pang +4
Uranium dioxide (UO), one of the most important nuclear fuels, can accumulate excess oxygen atoms as interstitial defects, which significantly impacts thermal properties. In th…
Implications of phonon anisotropy on thermal conductivity of fluorite oxides
Saqeeb Adnan, Miaomiao Jin, Matthew S Bryan +3
Fluorite oxides are attractive ionic compounds for a range of applications with critical thermal management requirements. In view of recent reports alluding to anisotropic thermal…
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…
Maxon and roton measurements in nanoconfined He
Matthew S. Bryan, Paul E. Sokol
We investigate the behavior of the collective excitations of adsorbed He in an ordered hexagonal mesopore, examining the crossover from a thin film to a confined fluid. Here we…
The Momentum Distribution of Liquid He
Timothy R. Prisk, Matthew S. Bryan, Paul. E. Sokol +3
We report high-resolution neutron Compton scattering measurements of liquid He under saturated vapor pressure. There is excellent agreement between the observed scattering and…
The Momentum Distribution of Liquid He
Matthew S. Bryan, Timothy R. Prisk, Richard T. Azuah +2
We present high-resolution neutron Compton scattering measurements of liquid He below its renormalized Fermi temperature. Theoretical predictions are in excellent agreement wit…
Superconducting proximity effects in metals with a repulsive pairing interaction
Oriol T. Valls, Matthew Bryan, Igor Zutic
Studies of the superconducting proximity effect in normal conductor/superconductor junctions almost universally assume no effective electron-electron coupling in the re…
