The charge density fluctuations and the Shrinking Fermi Liquid scenario for strange metallicity in cuprates
Sergio Caprara, Sauri Bhattacharyya, Carlo Di Castro +3
We interpret the strange metal (SM) properties of slightly overdoped cuprates in terms of the recently proposed Shrinking Fermi Liquid theory. This is based on the pervading presen…
Nematic fluctuations and the magneto-structural phase transition in
Florian Kretzschmar, Thomas Böhm, Una Karahasanović +11
An inelastic light (Raman) scattering study of nematicity and critical fluctuations in () is presented. It is shown that the respon…
Self-organized electronic superlattices in layered materials
Carmine Ortix, Carlo Di Castro, José Lorenzana
We show that in layered systems with electronic phase separation tendency, the long-range Coulomb interaction can drive the spontaneous formation of unidirectional superlattices of…
Luttinger liquid, singular interaction and quantum criticality in cuprate materials
C. Di Castro, S. Caprara
With particular reference to the role of the renormalization group approach and Ward identities, we start by recalling some old features of the one-dimensional Luttinger liquid as…
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…
Phase separation frustrated by the long range Coulomb interaction I: Theory
J. Lorenzana, C. Castellani, C. Di Castro
We analyze the combined effect of the long range Coulomb (LRC) interaction and of surface energy on first order density-driven phase transitions in the presence of a compensating r…
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…
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…
