New Route to Frustration by Quantum Many-Body Effects in the Spin Liquid Pyrochlore Tb$_2$Ti$_2$O$_7$
In this thesis we investigate the frustrated spin liquid Tb$_2$Ti$_2$O$_7$ theoretically. The low-energy effective Hamiltonian of this compound is derived by integrating out the excited crystal field states. It is shown that the pairwise interaction in the effective Hamiltonian is renormalized by...
