Charge critical fluctuations in cuprates: Isotope effect, pseudogap, conductivity, and Raman spectroscopy
C. Di Castro, M. Grilli, S. Caprara +1
Within the stripe quantum critical point theory for high T_c superconductors, we point out that there is a direct contribution of charge collective fluctuations to the optical abso…
Collective transport and optical absorption near the stripe criticality
C. Di Castro, S. Caprara, M. Grilli
Within the stripe quantum critical point scenario for high superconductors, we point out the possible direct contribution of charge collective fluctuations to the optical abs…
Charge-ordering quantum criticality in the phase diagram of the cuprates
C. Di Castro, M. Grilli, S. Caprara
We discuss how the quantum-critical-point scenario for high-T_c superconductors with density-driven charge order or stripe formation finds support from recent EXAFS experiments. Ou…
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,…
