Researchers have identified a new class of quantum states in a custom-engineered graphene structure. The study reports the discovery of topological electronic crystals in twisted bilayer -- trilayer ...
Electrons in these materials are free to move in the two-dimensional plane, but their restricted motion in the third direction is governed by quantum mechanics. Prominent examples include quantum ...
Phase transitions in two-dimensional (2D) systems are a fascinating area of study in condensed matter physics. These transitions describe how materials change from one state of matter to another ...
