Magnetic Monopoles in Spin Ice
Claudio Castelnovo, Roderich Moessner, Shivaji L. Sondhi
Electrically charged particles, such as the electron, are ubiquitous. By contrast, no elementary particles with a net magnetic charge have ever been observed, despite intensive and…

A quantum topological phase transition at the microscopic level
C. Castelnovo, C. Chamon
We study a quantum phase transition between a phase which is topologically ordered and one which is not. We focus on a spin model, an extension of the toric code, for which we obta…

Entanglement and topological entropy of the toric code at finite temperature
C. Castelnovo, C. Chamon
We calculate exactly the von Neumann and topological entropies of the toric code as a function of system size and temperature. We do so for systems with infinite energy scale separ…
