Geometric-Arithmetic Master Equation in Large and Fast Open Quantum Systems
Dragomir Davidovic
Understanding nonsecular dynamics in open quantum systems is addressed here, with emphasis on systems with large numbers of Bohr frequencies, zero temperature, and fast driving. We…
Hamiltonian Model for Fault Tolerant Singlet-Like Excitation: First Principles Approach
Donghyun Jin, Grihith Manchanda, Dragomir Davidovic
Deriving quantum error correction and quantum control from the Schrodinger equation for a unified qubit-environment Hamiltonian will give insights into how microscopic degrees of f…
Completely Positive, Simple, and Possibly Highly Accurate Approximation of the Redfield Equation
Dragomir Davidovic
Here we present a Lindblad master equation that approximates the Redfield equation, a well known master equation derived from first principles, without significantly compromising t…
Probing the Magnetodynamics of Magnetic Tunnel Junctions with the Aid of SiGe HBTs
Jason Dark, Hanbin Ying, Grant Nunn +2
High impedance (about 1 Megaohm) magnetic tunnel junctions (MTJs) are used to observe and record the magnetodynamics of the nanomagnets that form the junctions themselves. To count…
Exceptionally Strong Spin-Transfer in Single Ni Nanoparticles
P. Gartland, W. Jiang, D. Davidovic
This letter presents studies of spin-transfer efficiency in electron transport via discrete electron-in- a-box levels in individual nanometer-scale Ni particles at 0.06K temperatur…
Minimum Anisotropy of a Magnetic Nanoparticle out of Equilibrium
W. Jiang, P. Gartland, D. Davidovic
In this article we study magnetotransport in single nanoparticles of Ni, Py=NiFe, Co, and Fe, with volumes nm, using sequential electron tunneling at 4…
