Optimizing Finite Structures to Suppress the Photonic Density of States
Prakash Mishra, Sukhad Dnyanesh Joshi, Aditya Bahulikar +3
We propose a topology-optimization framework for optimizing finite structures of arbitrary shape by combining density-based methods with level-set approaches. We first optimize reg…
Computing Using Shallow NV-Center Charges in Diamond
Rodrick Kuate Defo, Steven L. Richardson
The static electric dipole-dipole coupling between donor-acceptor pairs (DAPs) in wide-bandgap semiconductors has recently emerged as a means of realizing a quantum science platfor…
Theoretical Investigation of Charge Transfer Between Two Defects in a Wide-Bandgap Semiconductor
Rodrick Kuate Defo, Alejandro W. Rodriguez, Efthimios Kaxiras +1
Charge traps in the semiconductor bulk (bulk charge traps) make it difficult to predict the electric field within wide-bandgap semiconductors. The issue is the daunting number of b…
Ultracoherent self-assembled diamond nanomechanics reveals superfluid dynamics
Guanhao Huang, Chang Jin, Sophie Weiyi Ding +9
From gravitational-wave detection, protein force microscopy, to exploration of quantum-classical boundaries, many anticipated discoveries in fundamental science require improving m…
Enhanced cavity coupling to silicon monovacancies in 4-H Silicon Carbide using below bandgap laser irradiation and low temperature thermal annealing
Mena N. Gadalla, Andrew S. Greenspon, Rodrick Kuate Defo +2
The negatively charged silicon monovacancy in 4H-silicon carbide (SiC) is a spin-active point defect that has the potential to act as a qubit or quantum memory in solid-…
Charge-State Stability of Color Centers in Wide-Bandgap Semiconductors
Rodrick Kuate Defo, Alejandro W. Rodriguez, Steven L. Richardson
The NV color center in diamond has been extensively investigated for quantum sensing, computation, and communication applications. Nonetheless, charge-state decay from the NV$^…
