On localization effects in underdoped cuprates
C. Castellani, P. Schwab, M. Grilli
We comment on transport experiments in underdoped LaSrCuO in the non-superconducting phase. The temperature dependence of the resistance strongly resembles what is expected from st…
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…
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…
Renormalization group analysis of the quantum non-linear sigma model with a damping term
Andrea Gamba, Marco Grilli, Claudio Castellani
We investigate the behavior of the zero-temperature quantum non-linear sigma model in d dimensions in the presence of a damping term of the form f(w)~ |w|^alpha, with 1 \le alpha <…
Stripe formation: A quantum critical point for cuprate superconductors
C. Castellani, C. Di Castro, M. Grilli
We discuss the effects of a quantum critical point located nearby optimum doping and related to local charge segregation (stripe phase). The fluctuations in the critical region pro…
Striped phases in the two-dimensional Hubbard model with long-range Coulomb interaction
G. Seibold, C. Castellani, C. Di Castro +2
We investigate the formation of partially filled domain walls in the two-dimensional Hubbard model in the presence of long-range interaction. Using an unrestricted Gutzwiller varia…
