Quantum Phase Transitions in Materials
1. What Are Phase Transitions? A phase transition occurs when a material changes its state, like ice melting into water or water boiling into vapor. These transitions happen when external….

2D Materials like Graphene
1. What Are 2D Materials? Two-dimensional (2D) materials are crystalline substances consisting of a single layer of atoms. While most materials are 3D in nature (length, width, and height), 2D….
Quantum Dots and Nanostructures
1. Introduction to Nanostructures Nanostructures refer to materials and devices engineered at the scale of nanometers—billionths of a meter. At these tiny dimensions, the behavior of matter is governed not….
High-Temperature Superconductors
1. Introduction to Superconductivity Superconductivity is a quantum mechanical phenomenon where a material conducts electricity without resistance when cooled below a certain critical temperature. In traditional superconductors, this temperature is….
Quantum Spin Liquids
1. What is a Quantum Spin Liquid? At first glance, the term “spin liquid” may sound like it refers to a state of matter similar to a regular liquid. But….
Majorana Fermions in Condensed Matter
1. Who or What Is a Majorana Fermion? The idea of a Majorana fermion originated from the Italian physicist Ettore Majorana in 1937. He proposed a type of fermion (a….
Quantum Hall Effect
1. The Classical Hall Effect: A Starting Point Before diving into the quantum version, it helps to understand the classical Hall effect. In 1879, Edwin Hall discovered that when an….
Topological Insulators
1. What Are Topological Insulators? Topological insulators are a class of quantum materials that behave in a very unusual way: This means their interior resists electric current, but their surface….
Experimental Evidence of Quantum Biology
1. Introduction: The Search for Quantum Life Quantum biology is the study of how quantum phenomena—such as superposition, entanglement, and tunneling—might play a functional role in biological systems. For decades,….
Decoherence in Biological Environments
1. Introduction: The Quantum-Biology Crossroad The idea that quantum effects might operate in biological systems has opened up an exciting new field of study. But this intersection between the weirdness….
