Spontaneous Symmetry Breakings in Gauge Theories for Doped Quantum Dimer and Eight-Vertex Models
Ikuo Ichinose, Daisuke Yoshioka
Behavior of doped fermions in gauge theories for the quantum dimer and eight-vertex models is studied. Fermions carry charge and spin degrees of freedom. In the confinement p…

Néel-Dimer Transition in Antiferromagnetic Heisenberg Model and Deconfinement of Spinons at the Critical Point
Daisuke Yoshioka, Gaku Arakawa, Ikuo Ichinose +1
Quantum phase transition from the Néel to the dimer states in an antiferromagnetic(AF) Heisenberg model on square lattice is studied. We introduce a control parameter for the e…
