Spin orthogonality catastrophe in two-dimensional antiferromagnets and superconductors.
We compute the spectral function of a spin S hole injected into a two-dimensional antiferromagnet or superconductor in the vicinity of a magnetic quantum critical point. We show that, near Van Hove singularities, the problem maps onto that of a static vacancy carrying excess spin S. The hole creation operator is characterized by a new boundary anomalous dimension and a vanishing quasiparticle r...
متن کاملQuantum Phases in Two-dimensional Frustrated Spin-1/2 Antiferromagnets
Investigating various spin-1/2 systems in two dimensions (2d), by means of exact diagonalization (ED) on small samples of N spins, we have found, up to now, four kinds of antiferromagnetic phases at T=0. Two of them display long range order (LRO): Néel or Valence Bond Crystal (VBC) LRO. The others are two different Spin-Liquids. The Néel case may be qualified as semi-classical: it is a groundst...
متن کاملMagnetocaloric effect in two-dimensional spin-1/2 antiferromagnets
The magnetocaloric effect is studied at the transition to saturation in the antiferromagnetic spin-1/2 Heisenberg model on the simplest two-dimensional lattices, namely the square and the triangular lattice. Numerical results are presented for the entropy which are consistent with identical universal properties. However, the absolute values of the entropy are bigger on the geometrically frustra...
متن کاملRaman spectra of two-dimensional spin-$ Heisenberg antiferromagnets
The Raman spectrum of two-dimensional spin-$ Heisenberg antiferromagnets is calculated by exactly diagonalizing clusters of up to 26 sites. The obtained spectra are compared to experimental results for various high-T, precursors, such as La,CuO, and YBa,Cu,O,,. In spite of good agreement in the position of the main excitation in the B rg channel, i.e, the two-magnon peak around 0.4 eV, an addit...
متن کاملBond-Dilution Effects on Two-Dimensional Spin-Gapped Heisenberg Antiferromagnets
Bond-dilution effects on spin-1/2 spin-gapped Heisenberg antiferromagnets of coupled alternating chains on a square lattice are investigated by means of the quantum Monte Carlo method. It is found that, in contrast with the site-diluted system having an infinitesimal critical concentration, the bond-diluted system has a finite critical concentration of diluted bonds, xc, above which the system ...
