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…
Analytical Forces from the Bethe-Salpeter Equation for Large-Scale Excited-State Relaxation
Yu Jin, Victor Wen-zhe Yu, Marco Govoni +1
We present an efficient plane-wave implementation of analytical nuclear forces for electronic excited states described by the Bethe-Salpeter equation (BSE). The formulation combine…
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…
Towards dislocation-driven quantum interconnects
Cunzhi Zhang, Victor Wen-zhe Yu, Yu Jin +4
A central problem in the deployment of quantum technologies is the realization of robust architectures for quantum interconnects. We propose to engineer interconnects in semiconduc…
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…
GPU-Accelerated Solution of the Bethe-Salpeter Equation for Large and Heterogeneous Systems
Victor Wen-zhe Yu, Yu Jin, Giulia Galli +1
We present a massively parallel, GPU-accelerated implementation of the Bethe-Salpeter equation (BSE) for the calculation of the vertical excitation energies (VEEs) and optical abso…
Many-body perturbation theory with hybrid density functional theory starting points accelerated by adaptively compressed exchange
Victor Wen-zhe Yu, Marco Govoni
We report on the use of the adaptively compressed exchange (ACE) operator to accelerate many-body perturbation theory (MBPT) calculations, including GW and the Bethe Salpet…
Excited state properties of point defects in semiconductors and insulators investigated with time-dependent density functional theory
Yu Jin, Victor Wen-zhe Yu, Marco Govoni +2
We present a formulation of spin-conserving and spin-flip, hybrid time-dependent density functional theory (TDDFT), including the calculation of analytical forces, which allows for…
