Doping-driven transition to a time-reversal breaking state in the phase diagram of the cuprates
G. Sangiovanni, M. Capone, S. Caprara +3
Motivated by recent tunnelling and Andreev-reflection experiments, we study the conditions for a quantum transition within the superconducting phase of the cuprates,in which a bulk…
Single-particle spectra near a stripe instability
S. Caprara, C. Di Castro, M. Grilli
We analyze the single-particle spectra of a bi-layered electron system near a stripe instability and compare the results with ARPES experiments on the Bi2212 cuprate superconductor…
Strong correlation, electron-phonon interaction and critical fluctuations: Isotope effect, pseudogap formation, and phase diagram of the cuprates
C. Di Castro, M. Grilli, S. Caprara
Within the Hubbard-Holstein model with long-range Coulomb forces, we revisit the charge-ordering scenario for the superconducting cuprates and account for the presence or the absen…
Anomalous optical absorption in overdoped cuprates near the charge-ordering instability
S. Caprara, C. Di Castro, S. Fratini +1
We propose an interpretation for the hump observed in the optical conductivity at or below a few hundreds of cm, in overdoped cuprates like the electron-doped Nd_{2-x}Ce_xCu…
Phase separation frustrated by the long range Coulomb interaction II: Applications
J. Lorenzana, C. Castellani, C. Di Castro
The theory of first order density-driven phase transitions with frustration due to the long range Coulomb (LRC) interaction develop on paper I of this series is applied to the foll…
