Quantum fluctuations in the spiral phase of the Hubbard model
C. Zhou, H. J. Schulz
We study the magnetic excitations in the spiral phase of the two--dimensional Hubbard model using a functional integral method. Spin waves are strongly renormalized and a line of n…

Dynamics of a hole in the large--U Hubbard model: a Feynman diagram approach
C. Zhou, H. J. Schulz
We study the dynamics of a single hole in an otherwise half--filled two--dimensional Hubbard model by introducing a nonlocal Bogolyubov transformation in the antiferromagnetic stat…
