    T-matrix calculations of spin-dependent optical forces in optically trapped nanowires

    We present computational results associated with the onset of a spin-dependent optical force component occurring on zinc oxide nanowires trapped in optical tweezers with circularly polarized light. This type o...

    Stable particles in anisotropic spin-1 chains

    Motivated by field-theoretic predictions we investigate the stable excitations that exist in two characteristic gapped phases of a spin-1 model with Ising-like and single-ion anisotropies. The sine-Gordon the...

    Low-Dimensional Spin Systems: Hidden Symmetries, Conformal Field Theories and Numerical Checks

    We review here some general properties of antiferromagnetic Heisenberg spin chains, emphasizing and discussing the rôle of hidden symmetries in the classification of the various phases of the models. We presen...

    Investigation of quantum phase transitions using multi-target DMRG methods

    In this paper we examine how the predictions of conformal invariance can be widely exploited to overcome the difficulties of the density-matrix renormalization group near quantum critical points. The main idea...

    On \(\mathsf{c = 1}\) critical phases in anisotropic spin-1 chains

    Quantum spin-1 chains may develop massless phases in presence of Ising-like and single-ion anisotropies. We have studied c = 1 critical phases by means of both analytical techniques, including a map** of the la...
