Nitrogen Vacancy Centers in Hexagonal Diamond Exhibit Long Coherence Times
Gabriel Kumar, Siyuan Chen, Victor Wen-zhe Yu +1
We show that negatively charged nitrogen-vacancy (NV) centers in the hexagonal diamond polymorph lonsdaleite offer a route to spin qubits with enhanced coherence relative to their…
The WEST code for large-scale excited-state materials simulations
Victor Wen-zhe Yu, Siyuan Chen, Yu Jin +5
We present WEST, an open-source plane-wave pseudopotential code for large-scale excited-state materials simulations, and describe its theoretical foundations, software architecture…
Advances in Quantum Defect Embedding Theory
Siyuan Chen, Victor Wen-zhe Yu, Yu Jin +2
Quantum defect embedding theory (QDET) is a many-body embedding method designed to describe condensed systems with correlated electrons localized within a given region of space, fo…
Strongly correlated states of transition metal spin defects: the case of an iron impurity in aluminum nitride
Leon Otis, Yu Jin, Victor Wen-zhe Yu +3
We investigate the electronic properties of an exemplar transition metal impurity in an insulator, with the goal of accurately describing strongly correlated, defect states. We con…
