Gravitationally dressed RG flows and zigzaginvariant strings hepth/9807223
"... We propose a worldsheet realization of the zigzaginvariant bosonic and fermionic strings as a perturbed WessZuminoNovikovWitten model at large negative level k on a group manifold G coupled to 2D gravity. In the large k limit the zigzag symmetry can be obtained as a result of a selfconsistent ..."

Zigzag Structure of Simple Bifaced Polyhedra
, 2008
"... A zigzag in a plane graph is a circuit of edges such that any two, but no three, consecutive edges belong to the same face. A railroad in a plane graph is a circuit of hexagonal faces, such that any hexagon is adjacent to its neighbors on opposite edges. A graph without railroad is called tight. We ..."

structure and symmetry groups for the case (a,b)=(3,6). For the case (a,b)=(4,6) we describe symmetry groups, classify all tight graphs with simple zigzags and give upper bound 9 for the number of zigzags in general tight graph. For the remaining case (a,b)=(5,6) we give a construction realizing prescribed

A strongly coupled zigzag transition
"... The zigzag symmetry transition is a phase transition in 1D quantum wires, in which a Wigner lattice of electrons transitions to two staggered lattices. Previous studies model this transition as a Luttinger liquid coupled to a Majorana fermion. The model exhibits interesting RG flows, involving que ..."

Meanfield theory for Heisenberg zigzag ladder: Ground state energy and spontaneous symmetry breaking
, 2006
"... Dedicated to the memory of Daniel Arnaudon The spin1/2 zigzag Heisenberg ladder (J1 − J2 model) is considered. A new representation for the model is found and a saddle point approximation over the spinliquid order parameter 〈σn−1(σn × σn+1) 〉 is performed. Corresponding effective action is derive ..."

Filamentary hightemperature superconductor (HTSC) theory diŒers fundamentally from continuous HTSC theories because it emphasizes selforganized discrete dopant networks and does not make the eŒectivemedium approximation. Analysis of neutron and infrared (especially with caxis polarization) vibrational spectra, primarily for YBa2Cu3O6‡x, within the ®lamentary framework, shows that the observed vibronic anomalies near 400 cm 1 (50meV) are associated with curvilinear ®lamentary paths. These paths pass through the cuprate chains and planes, as well as resonant tunnelling centres in the BaO layers. The analysis and the data con®rm earlier ®lamentary structural models containing ferroelastic domains of diameter 3±4 nm in the CuO2 planes; it is these nanodomains that are responsible for the discrete glassy nature of both electronic and vibrational properties. Chemical trends in vibronic energies and oscillator strengths, for both neutron and photon scattering, that were anomalous in continuum models, are readily explained by the ®lamentary model.
ZIGZAG AND CENTRAL CIRCUIT STRUCTURE OF ({1, 2, 3}, 6)SPHERES
"... Abstract. We consider 6regular plane graphs whose faces have size 1, 2 or 3. In Section 2 a practical enumeration method is given that allowed us to enumerate them up to 53 vertices. Subsequently, in Section 3 we enumerate all possible symmetry groups of the spheres that showed up. In Section 4 we ..."

αSymmetries, Coloured Dimensions and GaugeString Correspondence

"... We propose a scenario of gaugestring correspondence by relating the SU(3) colour group to hidden spacetime isometries originating from extra dimensions. These isometries ( αsymmetries) are the special symmetries of RNS superstring theories under global nonlinear spacetime transformations. The v ..."

As a result, the scattering amplitudes of the constructed open string vertex operators have a fieldtheoretic rather than a stringy structure, including the absense
