Speaker : Mr. Jonas Sonnenschein from Freie University of Berlin.

 

[Abstract]

Quantum spin liquids are phases of matter that do not develop any magnetic order at low temperatures. The usual description of magnetism based on a mean-field theory of the spin operators is therefore bound to fail. In this talk an alternative approach using a fermionic representation is presented. This formalism is then applied in order to explain the experimental data of the quantum spin liquid candidate  Ca10Cr7O28.
