In this post, I aim to provide some qualitative understanding of some of the ways we can use neutrons to understand magnetism.  Neutrons are a powerful probe of condensed matter allowing us to

Machine Learning In order to learn something, you have to make a series of assumptions about the problem at hand. We make decision based on a set of beliefs and machine learning (ML) tries to place a

This is a must listen. Enjoy!

Footwork There are four main areas of the feet that we use during climbing: Inside edge Outside Edge Heel Toe The major take home point for beginners is to only use the very edges of your shoe. You can

We all learned about isolated electric charges in high school. These are the reason why balloons stick to walls after rubbing them on a course surface such as your jumper - the electric charges are manipulated

Think about spins coupled antiferromagnetically on a triangle lattice. Consider the lower two vertices - if the spins on these sites are arranged with one 'up' and one 'down' then we minimise the energy,

Spin ice is the name given to a class of magnetic materials that have a property called frustration, which occurs due to the lattice geometry - the way the atoms are arranged inside the crystal. These

each type of lattice has a condition associated with it that describes positive interference during scattering. this is encapsulated within the so-called structure factor and explains the systematic absenses

we can look inside crystals using x-rays and neutrons.  in the simplest case of elastic scattering, the incoming and outgoing wavevectors have the same magnitude, that is |k| = 2 π /λ  . here,

The Meissner effect 'in-action'. [ image source ] Conduction in metals The notion that metals are good electrical conductors because the electrons move freely between the atoms, in sort of a delocalised

 Previous posts: I, II, III, IV, V, VI, VII, VIII Welcome, one and all, to your series of posts on magnetism. This marks the ninth  instalment, and it is with great pleasure that I announce we

In the same way that life, itself, is an emergent phenomena in biology, so too are many fascinating condensed matter systems. The big examples are ferromagnetism, and superconductivity. In ferromagnetism,

Personal favourite of mine, this. Big tune; good vibes. Enough said. Any other DnB fans out there, Steemit?

First post on climbing in quite a while. Thought I'd share a recent escapade - this font 7b roof problem was an absolute delight to climb on; can't get enough of the dirty crimps!  Watch this space,

Feynman diagrams are an ingenious way of describing particle interactions; that is, events in which two particles come speeding towards each other and then smash apart! What we have just crudely described
