Engineering diamond interfaces free of dark spins
Xiaofei Yu, Evan J. Villafranca, Stella Wang +10
Nitrogen-vacancy (NV) centers in diamond are extensively utilized as quantum sensors for imaging fields at the nanoscale. The ultra-high sensitivity of NV magnetometers has enabled…
Suppression of charge-density wave and superconductivity in a lithiated NbSe monolayer
Hari Paudyal, Michael E. Flatté
We present an \textit{ab initio} investigation of the long-range charge density wave (CDW) order and superconducting properties of the pristine and lithiated NbSe monolayer. St…
Microscopic Scattering Approach to In-Gap States: Cr Adatoms on Superconducting β-Bi2Pd
Joseph Sink, Hari Paudyal, Divya Jyoti +4
We develop a microscopic scattering formalism to describe Yu-Shiba-Rusinov (YSR) states due to a single Cr adatom on the Bi-terminated surface of , by combining ab initi…
Spin-State Selective Excitation in Spin Defects of Hexagonal Boron Nitride
Mohammad Abdullah Sadi, Luca Basso, David A Fehr +8
Hexagonal boron nitride (hBN) has emerged as a promising two-dimensional platform for quantum sensing, due to its optically addressable spin defects, such as the negatively charged…
Imaging the Acceptor Wave Function Anisotropy in Silicon
Manuel Siegl, Julian Zanon, Joseph Sink +5
We present the first scanning tunneling microscopy (STM) images of hydrogenic acceptor wave functions in silicon. These acceptor states appear as square ring-like features in STM i…
Crystal fields, exchange, and dipolar interactions and noncollinear magnons of erbium oxide
Kian Maleki, Michael E. Flatté
We simulate the properties of magnons in erbium oxide, a noncollinear antiferromagnet, from an effective single-ion Hamiltonian, including exchange and long-range dipolar interacti…
