Boundary Critical Phenomena in SU(3) “Spin” Chains
SU(3)-invariant “spin” chains with a single impurity, such as a modified exchange coupling on one link, are analyzed using boundary conformal field theory techniques. These chains are equivalent to a special case of the “tJV ” model, i.e. the tJ model with a nearest neighbour repulsion added. In the continuum limit they are equivalent to two free bosons at a special value of the compactificatio...
متن کاملRandom matrix theory and critical phenomena in quantum spin chains.
We compute critical properties of a general class of quantum spin chains which are quadratic in the Fermi operators and can be solved exactly under certain symmetry constraints related to the classical compact groups U(N),O(N), and Sp(2N). In particular we calculate critical exponents s,ν, and z, corresponding to the energy gap, correlation length, and dynamic exponent, respectively. We also co...
متن کاملSymmetric Boundary Conditions in Boundary Critical Phenomena
It has been an extremely fruitful idea to study a conformal field theory by putting it on various surfaces, with or without boundaries. Apart from the sphere, that has been considered first, prime examples of non–trivial geometries include the torus [1] and the cylinder [2,3]. They serve to probe different facets of a given conformal theory. However the data specific of these surfaces are inext...
متن کاملEntanglement at the boundary of spin chains near a quantum critical point and in systems with boundary critical points
We analyze the entanglement properties of spins (qubits) attached to the boundary of spin chains near quantum critical points, or to dissipative environments, near a boundary critical point, such as Kondo-like systems or the dissipative two level system. In the first case, we show that the properties of the entanglement are significantly different from those for bulk spins. The influence of the...
متن کاملCRITICAL PHENOMENA OF ANISOTROPIC SPIN GLASS ZnMn
Longitudinal (11 c) and transverse (LC) nonlinear susceptibilities have been measured on the Ising-type ZnMn spin glass. The critical exponents obtained from the scaling hypothesis depend on the anisotropy/exchange ratio, which can suggest a crossover effect from Heisenberg to Ising spin glasses in real RKKY systems. Critical behaviors of the nonlinear susceptibility in spin glasses have been e...
