Zsolt Benedek, Ãdám Ganyecz, Oscar Bulancea-Lindvall +2
Ensembles of negatively charged boron vacancy (V) centers in hexagonal boron nitride (hBN) have emerged as a two-dimensional spin qubit system interfaced with optics…
Demonstration of the ODMR activity of the telecom range ClV center in SiC: a wavefunction theory analysis
Zsolt Benedek, Oscar Bulancea-Lindvall, Joel Davidsson +2
Recently, density functional theory-based high-throughput screening of point defects in 4H-SiC revealed the positively charged chlorine-vacancy (ClV) defect to be a promising quant…
Assessing the Reliability of Truncated Coupled Cluster Wavefunction: Estimating the Distance from the Exact Solution
Ãdám Ganyecz, Zsolt Benedek, Klára Petrov +4
A new approach is proposed to assess the reliability of the truncated wavefunction methods by estimating the deviation from the full configuration interaction (FCI) wavefunction. W…
