Schwinger boson theory of anisotropic ferromagnetic ultrathin films
Carsten Timm, P. J. Jensen
Ferromagnetic thin films with magnetic single-ion anisotropies are studied within the framework of Schwinger bosonization of a quantum Heisenberg model. Two alternative bosonizatio…

Theory for underdoped high-T_c superconductors: effects of phase fluctuations
F. Schaefer, C. Timm, D. Manske +1
In underdoped cuprates, T_c is thought to be determined by Cooper pair phase fluctuations because of the small superfluid density n_s. Experimentally, T_c is found to scale with n_…

Monte Carlo study of a two-dimensional quantum ferromagnet
Patrik Henelius, Anders W. Sandvik, Carsten Timm +1
We present quantum Monte Carlo results for the field and temperature dependence of the magnetization and the spin-lattice relaxation rate of a two-dimensional quant…
