The Stripe-Phase Quantum-Critical-Point Scenario for High-Tc Superconductors
S. Caprara, C. Castellani, C. Di Castro +3
A summary is given of the main outcomes of the quantum-critical-point scenario for high- superconductors, developed in the last few years by the Rome group. Phase separation,…
Fermi Surface and gap parameter in high-Tc superconductors: the Stripe Quantum Critical Point scenario
S. Caprara, C. Di Castro, M. Grilli +2
We study the single-particle spectral properties of electrons coupled to quasicritical charge and spin fluctuations close to a stripe-phase, which is governed by a Quantum Critical…
Critical properties and phase diagram of the quantum anisotropic XY spin chain in a random magnetic field: A density-matrix renormalization-group analysis
A. Juozapavicius, L. Urba, S. Caprara +1
The spin-1/2 quantum anisotropic XY spin chain in a transverse random magnetic field parallel to the z axis is numerically studied by means of the density-matrix renormalization gr…
Shadow bands, gap and pseudogaps in high-T_c superconductors
S. Caprara, A. Perali, M. Sulpizi
Within the framework of the Charge Density Wave Quantum Critical Point (CDW-QCP) scenario for high-T_c superconductors (HTCS), we introduce a model for tight-binding electrons coup…
Single-particle properties of a model for coexisting charge and spin quasi-critical fluctuations coupled to electrons
S. Caprara, M. Sulpizi, A. Bianconi +2
We study the single-particle spectral properties of a model for coexisting AFM and ICDW critical fluctuations coupled to electrons, which naturally arises in the context of the str…
