SU(2) approach to the pseudogap phase of high-temperature superconductors: Electronic spectral functions

Samuel Bieri

We use an SU(2) mean-field theory approach with input from variational wave functions of the t-J model to study the electronic spectra in the pseudogap phase of cuprates. In our model, the intermediate-temperature state of underdoped cuprates is realized b ...

Resonating-valence-bond approaches to high-temperature superconductivity

This thesis is devoted to a theoretical study of high-temperature superconductivity from the viewpoint of a doped Mott insulator. To this end, the square-lattice t-J model is analyzed by variational and mean-field approaches. The thesis focuses on the cons ...

Single hole and vortex excitations in the doped Rokhsar-Kivelson quantum dimer model on the triangular lattice

Dmitri Ivanov, Samuel Bieri, Hugo Ribeiro

We consider the doped Rokhsar-Kivelson quantum dimer model on the triangular lattice with one mobile hole (monomer) at the Rokhsar-Kivelson point. The motion of the hole is described by two branches of excitations: the hole may either move with or without ...
