2-D Topological Physics

Authors: George Rajna

Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. [24] Topological effects, such as those found in crystals whose surfaces conduct electricity while their bulk does not, have been an exciting topic of physics research in recent years and were the subject of the 2016 Nobel Prize in physics. [23] A new technique developed by MIT researchers reveals the inner details of photonic crystals, synthetic materials whose exotic optical properties are the subject of widespread research. [22] In experiments at SLAC, intense laser light (red) shining through a magnesium oxide crystal excited the outermost “valence” electrons of oxygen atoms deep inside it. [21]
