Spectroscopic evidences of quantum critical charge fluctuations in cuprates
M. Grilli, S. Caprara, C. Di Castro +1
We calculate the optical conductivity in a clean system of quasiparticles coupled to charge-ordering collective modes. The absorption induced by these modes may produce an anomalou…
Charge-fluctuation contribution to the Raman response in superconducting cuprates
S. Caprara, C. Di Castro, M. Grilli +1
We calculate the Raman response contribution due to collective modes, finding a strong dependence on the photon polarizations and on the characteristic wavevectors of the modes. We…
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…
Universality classes for depinning transitions of two heteropolymers
Domenico Suppa
We study a solid-on-solid model for depinning transitions of two directed heteropolymers with an effective long range interaction decaying as the inverse square of their distance.…
Currents and correlations in Luttinger liquids and carbon nanotubes at finite temperature and size: a bosonization study
J. -S. Caux, A. Lopez, D. Suppa
We consider problems of one dimensional interacting fermions confined to a finite size, multichannel geometry. Concentrating on Luttinger liquids and carbon nanotubes, we use nontr…
Phase-ordering dynamics of binary mixtures with field-dependent mobility in shear flow
G. Gonnella, A. Lamura, D. Suppa
The effect of shear flow on the phase-ordering dynamics of a binary mixture with field-dependent mobility is investigated. The problem is addressed in the context of the time-depen…
