Upper bounds on the highest phonon frequency and superconducting temperature from fundamental physical constants
K. Trachenko, B. Monserrat, M. Hutcheon +1
Fundamental physical constants govern key effects in high-energy particle physics and astrophysics, including the stability of particles, nuclear reactions, formation and evolution…
Superconducting incommensurate host-guest phases in compressed elemental sulfur
Jack Whaley-Baldwin, Michael Hutcheon, Chris J. Pickard
We use Density Functional Theory (DFT) and structure searching methods to show that the ground state of elemental sulfur is a Barium-IVa type incommensurate host-guest (HG) phase b…
Design Principles for High Temperature Superconductors with Hydrogen-based Alloy Backbone at Moderate Pressure
Zihan Zhang, Tian Cui, Michael J. Hutcheon +7
Hydrogen-based superconductors provide a route to the long-sought goal of room-temperature superconductivity, but the high pressures required to metallize these materials limit the…
High-throughput discovery of high-temperature conventional superconductors
Alice M. Shipley, Michael J. Hutcheon, Richard J. Needs +1
We survey the landscape of binary hydrides across the entire periodic table from 10 to 500 GPa using a crystal structure prediction method. Building a critical temperature ()…
Predicting novel superconducting hydrides using machine learning approaches
Michael J. Hutcheon, Alice M. Shipley, Richard J. Needs
Searching for superconducting hydrides has so far largely focused on finding materials exhibiting the highest possible critical temperatures (). This has led to a bias towards…
Stability and superconductivity of lanthanum and yttrium decahydrides
Alice M. Shipley, Michael J. Hutcheon, Mark S. Johnson +2
Rare-earth hydrides can exhibit high-temperature superconductivity under high pressure. Here, we apply a crystal structure prediction method to the current record-holding mat…
Stochastic nodal surfaces in quantum Monte Carlo calculations
Michael Hutcheon
Treating the fermionic ground state problem as a constrained stochastic optimization problem, a formalism for fermionic quantum Monte Carlo is developed that makes no reference to…
Structural and vibrational properties of lithium under ambient conditions within density functional theory
Michael Hutcheon, Richard Needs
We apply a general first-principles approach to derive the phase diagram of metallic Lithium at ambient pressure between 0 and 350 K, including identification of candidate phases.…
A Zero-Gravity Instrument to Study Low Velocity Collisions of Fragile Particles at Low Temperatures
D. M. Salter, D. Heißelmann, G. Chaparro +14
We discuss the design, operation, and performance of a vacuum setup constructed for use in zero (or reduced) gravity conditions to initiate collisions of fragile millimeter-sized p…
