What Makes a Magnet a Magnet?
What makes a magnet a magnet? From ancient lodestones to quantum spins, our understanding of magnetism has come a long way. This post explores the journey from classical theories to the quantum interactions that govern magnetic materials, revealing how tiny electron spins shape the magnetic world around us.

Superconductivity: The High-Tc Puzzle
We have come to the last chapter on our superconductivity journey (for now). After finally understanding how superconductivity works, there was only one thing left to do: find materials with higher transition temperatures. In 1986, researchers did just that, but the superconductivity was not the same as before. The mechanism behind this new superconductivity is…

Superconductivity: Decoding the Transition
uperconductivity is more than just a macroscopic phenomenon—it’s rooted in the collective behavior of electrons. In this post, we explore the Ginzburg-Landau theory, which bridges the gap between the microscopic and macroscopic worlds, offering a deeper understanding of how superconductivity arises. From the role of the order parameter to the physics of phase transitions, we…

Superconductivity: Origins
This is the first post in a series on superconductivity. In this post, we will explore the origins of this remarkable phenomenon, starting with its unexpected discovery by Heike Kamerlingh Onnes. We will then move on to the new physics revealed by the Meissner effect and the initial attempts to describe superconductivity mathematically.
