Rotation symmetries are obvious symmetries This model naturally explains the basic phenomenology of the high-Tc superconductors from the insulating to the underdoped and the optimally doped region.Įmery and Kivelson (11) presented evidence that the SC transition on the underdoped side of the oxides can be described byĪ renormalized classical XY model. Model that describes the phase diagram and the effective low-energy dynamics of the This symmetry enables the construction of a SO(5) quantum nonlinear s The approximate SO(5) symmetry has been derived from the microscopic Hamiltonian, and it becomes exact under renormalization group flow toward aīicritical point. The complex phase diagram of high–critical temperature ( Tc) superconductors can beĭeduced from an SO(5) symmetry principle that unifies antiferromagnetism and d-wave This copy is for your personal, non-commercial use only.
