Mesoscopics Nanophysics Statistical Mechanics

Quantum states in disordered solids are characterized by wild spatial fluctuations. As a result, the behavior of a single typical wave function differs markedly from the ensemble average.


Quasiparticle doppelgängers

Semiconductor Physics Mesoscopics

By exploiting the concept of particle-hole duality, one can realize a point junction between integer and fractional quantum Hall phases, which constitutes a crucial building block towards possible applications of the quantum Hall effect.

Observing unification on a grand scale

Aaron Pierce, Physics 2, 44 (2009) – Published May 26, 2009

Particles & Fields Astrophysics

New connections have been made between experimental astrophysical signatures and theories that unify the electromagnetic, weak, and strong forces, called grand unified theories.


Is a room-temperature, solid-state quantum computer mere fantasy?

Quantum Information Spintronics

Creating a practical solid-state quantum computer is seriously hard. Getting such a computer to operate at room temperature is even more challenging. Is such a quantum computer possible at all? If so, which schemes might have a chance of success?
