Room Temperature Superconductivity Revolution: Foreshadowed by Victorians, Enabled by Millenials
Warren E. Pickett
Room temperature superconductivity has been the most prominent, highly ambitious, but still imaginable, acme of materials physics for half a century. The struggle toward this revol…
Survey of the class of isovalent antiperovskite alkaline earth-pnictide compounds
Wen Fong Goh, Warren E. Pickett
The few reported members of the antiperovskite structure class of alkaline earth ( = Ca,Sr,Ba) pnictides ( = N,P,As,Sb,Bi) compounds are all based on the B-s…
Local nematic susceptibility in stressed BaFeAs from NMR electric field gradient measurements
T. Kissikov, R. Sarkar, M. Lawson +10
The electric field gradient (EFG) tensor at the As site couples to the orbital occupations of the As p-orbitals and is a sensitive probe of local nematicity in BaFeAs$_2…
All 3d electron-hole bilayers in CrN/MgO(111) multilayers
Antia S. Botana, Victor Pardo, Warren E. Pickett
CrN/MgO(111) multilayers modeled via \textit{ab initio} calculations give rise to nanoscale, scalable, spatially separated two-dimensional electron and hole gases (2DEG+2DHG), each…
A single nodal loop of accidental degeneracies in minimal symmetry: triclinic CaAs
Y. Quan, Z. P. Yin, W. E. Pickett
The existence of closed loops of degeneracies in crystals has been intimately connected to associated crystal symmetries, raising the question: what is the minimum symmetry require…
