Schwinger Bosons Approaches to Quantum Antiferromagnetism

Understand

These lectures review the large N Schwinger Bosons Mean Field approach to the quantum Heisenberg model.

• The method applies to ordered and disordered phases in all dimensions, at zero and at finite temperature.
• Extension to frustrated models is explained.
• An example for an experimentally useful application, is the temperature dependent staggered magnetization of the layered antiferromagnet.
