Quantum discord and quantum phase transition in spin chains
Raoul Dillenschneider
Quantum phase transitions of the transverse Ising and antiferromagnetic XXZ spin S=1/2 chains are studied using quantum discord. Quantum discord allows the measure of quantum corre…

Kekule-distortion-induced Exciton instability in graphene
Raoul Dillenschneider
Effects of a Kekule distortion on exciton instability in single-layer graphene are discussed. In the framework of quantum electrodynamics the mass of the electron generated dynamic…
