Shoucheng Zhang | Search and Discovery of the Majorana Fermion | 2 of 2

The Majorana fermion is a hypothetical fermionic particle which is its own anti-particle.  Intense research efforts focus on its experimental observation as a fundamental particlein high energy physics and as a quasi-particle in condensed matter systems.  Professor Zhang discusses the theoretical prediction and the experimental discovery of the chiral Majorana fermion in a topological state of quantum matter.

For the past 60 years, progress in information technology has been governed by Moore's law, which states that the number of transistors on a semiconductor chip doubles every 18 months. However,  this remarkable trend is drawing to a close, mostly because the electrons that carry current in chips move like cars driving through a crowded marketplace, swerving around obstacles and dissipating too much of their energy as heat.

From Black Holes to Superconductors - Part 2/2

Black holes have the remarkable property of irreversibility: if you fall into a black hole you can't get out (classically). This immediately suggested a connection with the other famous irreversibility in physics: the law of increase of entropy. Since the 70s, this connection between black holes and thermodynamic systems has been fleshed out in increasing detail and has lead to surprising conclusions.

If a pebble is thrown into a black hole, an observer outside the black hole will see waves of energy diffuse outwards along the event horizon.

Stanford Physicists Xiao-Liang Qi and Leonardo Senatore won New Horizons in Physics Prizes for their outstanding contributions to fundamental physics.

Ground states of quantum matter can often be distinguished by their zero temperature electrical properties.  This way, superconductors, metals and insulators have zero, finite, and infinite resistance respectively, at T=0.  In two dimensions, it is widely believed that only superconductors, insul
