Explicit Exchange Interaction and Decoherence Dynamics in One-Dimensional Quantum Systems

Explicit Exchange Interaction and Decoherence Dynamics in One-Dimensional Quantum Systems

In this thesis, we investigate two aspects of one-dimensional interacting quantum systems. The first one is the effect of explicit antiferromagnetic exchange interactions on the quantum phase transitions of a one-dimensional itinerant electron system. The second one is the decoherence of a qubit...
