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: The Quantum Framework
It is the second half of the ’50s, and major global events are unfolding. In the meantime, a physics revolution is on the horizon. Bardeen, Cooper, and Schrieffer join forces, each contributing essential pieces to the BCS theory—the quantum answer to the superconductivity puzzle.

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.
