Particle-hole symmetry reveals failed superconductivity in the metallic phase of two-dimensional superconducting films
Nicholas P. Breznay, Aharon Kapitulnik
Electrons confined to two dimensions display an unexpected diversity of behaviors as they are cooled to absolute zero. Noninteracting electrons are predicted to eventually "localiz…
Quasiparticles and charge transfer at the two surfaces of the honeycomb iridate NaIrO
L. Moreschini, I. Lo Vecchio, N. P. Breznay +10
Direct experimental investigations of the low-energy electronic structure of the NaIrO iridate insulator are sparse and draw two conflicting pictures. One relies on flat ba…
Superconductor to weak-insulator transitions in disordered Tantalum Nitride films
Nicholas P. Breznay, Mihir Tendulkar, Li Zhang +2
We study the two-dimensional superconductor-insulator transition (SIT) in thin films of tantalum nitride. At zero magnetic field, films can be disorder-tuned across the SIT by adju…
Field-induced intertwined orders in 3D Mott-Kitaev honeycomb -Li2IrO3
Alejandro Ruiz, Alex Frano, Nicholas P. Breznay +7
Honeycomb iridates are thought to have strongly spin-anisotropic exchange interactions that could lead to an extraordinary state of matter known as the Kitaev quantum spin liquid.…
Resonant x-ray scattering reveals possible disappearance of magnetic order under hydrostatic pressure in the Kitaev candidate -LiIrO
Nicholas P. Breznay, Alejandro Ruiz, Alex Frano +4
Honeycomb iridates such as -LiIrO are argued to realize Kitaev spin-anisotropic magnetic exchange, along with Heisenberg and possibly other couplings. While systems with…
