p-Bits for Quantum-inspired Algorithms
Online Presentations | 12 Nov 2019 | Contributor(s): Supriyo Datta
This talk draws attention to something in-between that could be viewed as a poor man’s q-bit, namely, a p-bit which is a robust classical entity fluctuating between 0 and 1, and can be built with existing technology to operate at room temperature.
p-bits for Probabilistic Spin Logic (PSL): A Brief Introduction
Online Presentations | 02 Jul 2018 | Contributor(s): Supriyo Datta
Digital electronics is based on stable bits that can have one of two values, 0 and 1. At the other extreme we have quantum computing using using q-bits that can be in superposition states that are 0 and 1 at the same time. In our recent work we have introduced a concept that is intermediate...

Lessons From Nanoelectronics
Online Presentations | 09 Dec 2015 | Contributor(s): Supriyo Datta
This talk is about a less-appreciated by-product of the microelectronics revolution, namely the deeper understanding of current flow, energy exchange and device operation that it has enabled, which forms the basis for what we call the bottom-up approach.
Non-Equilibrium Green's Function (NEGF): A Different Perspective
Online Presentations | 17 Sep 2015 | Contributor(s): Supriyo Datta
The NEGF method was established in the 1960’s through the classic work of Keldysh and others [1] using the methods of many- body perturbation theory (MBPT) and this approach is widely used in the literature [2]. By contrast I have introduced a different approach starting with the...

Quantitative Model for TMR and Spin-transfer Torque in MTJ devices
Papers | 01 Sep 2013 | Contributor(s): Deepanjan Datta, Behtash Behin-Aein, Sayeef Salahuddin, Supriyo Datta
We present a Non-Equilibrium Green's Function (NEGF)-based model for spin torque transfer (STT) devices which provides qualitative as well as quantitative agreement with experimentally measured (1) differential resistances, (2) Magnetoresistance (MR), (3) In-plane torque (τ||) and (4)...
Voltage Asymmetry of Spin-Transfer Torques
Experimentally, it is seen that the free magnetic layer of a spin torque transfer (STT) device experiences a larger in-plane torque when a negative (rather than positive) voltage is applied to the fixed layer. This is surprising because magnets do not have any intrinsic asymmetry. In this paper,...
