Skew-Symmetric Differential qd Algorithm [PDF]
Applied Numerical Analysis & Computational Mathematics, 2005 Differential qd (dqd) algorithm with shifts is probably the fastest known algorithm which computes eigenvalues of symmetric tridiagonal matrices with high relative accuracy. In this paper we will construct a similar algorithm for computing eigenvalues of skew-symmetric matrices, which is based on implicit usage of both the QR and the symplectic QR ...

QD floating gate NVRAM using QD channel for faster erasing [PDF]
Electronics Letters, 2018 A new pathway to design floating gate quantum dot (QD) non‐volatile RAM (QDNVRAM) cells that possess high‐speed low‐voltage Erase capabilities not possible with conventional floating gate NV memories is presented. This is achieved by directly accessing the QD floating gate layer with an additional drain (D2) during the Erase operation.
