On Monday, June 3, 2019, at 4.30 pm, the Jerzy Pniewski and Leopold Infeld Colloquium of the Faculty of Physics will be held in room 0.03. Our guest will be Professor John Gregg from Oxford University, UK. He will give a lecture:
Magnon-inspired novel computing paradigms.

Professor Gregg's lecture will introduce us to a relatively young field of physics, called magnonics. Magnonics deals with collective excitations of spins in crystal. We will learn, among others, about hopes connected with the use of the phenomenon of spin waves in the construction of a new type of electronic devices. Such devices would offer higher speed of information processing and lower energy consumption in relation to the currently used silicon electronic devices.

A summary of the lecture is presented below.

Before the Colloquium, at 4 p.m., we invite you to informal discussions over coffee and cookies in the hall in front of room 0.03.

Lecture summary:
Magnonics is a prime contender for breaking the heat-induced log-jam that has paralysed computing speed for over a decade. It offers the triple selling points of ultra-low power dissipation, enormous potential speed and ultimate nanoscale realisation. Already, promising magnonic logic gate architectures are reported as performing very favourably. Conventional electronics is here to stay, so any such magnonic information processor will sit as a high-performance computing island in a sea of silicon infrastructure. Low power magnonic-electronic interfaces are already under development. However, the lure of magnonic computing goes far beyond the banal copying of conventional computing architecture and magnonic devices already exist that can perform functions which silicon cannot emulate. Rather than allowing hardware development to remain enslaved to software demands, Magnonics offers the possibility of entirely novel computing paradigms that maximally exploit its unusual capabilities. One such example is its potential for removing the traditional divide between analogue and digital computing to combine the power and speed of the former with the versatility of the latter.
