Clusterization of weakly-interacting bosons in one dimension: an analytic study at zero temperature
S. Prestipino, A. Sergi, E. Bruno
We study a system of penetrable bosons on a line, focusing on the high-density/weak-interaction regime, where the ground state is, to a good approximation, a condensate. Under comp…
Freezing of soft-core bosons at zero temperature: A variational theory
Santi Prestipino, Alessandro Sergi, Ezio Bruno
The properties of a macroscopic assembly of weakly-repulsive bosons at zero temperature are well described by Gross-Pitaevskii mean-field theory. According to this formalism the sy…
Coarse grained Density Functional theory of order-disorder phase transitions in metallic alloys
Ezio Bruno, Francesco Mammano, Beniamino Ginatempo
The technological performances of metallic compounds are largely influenced by atomic ordering. Although there is a general consensus that successful theories of metallic systems s…
Coarse Grained Density Functional Theories for Metallic Alloys: Generalized Coherent Potential Approximations and Charge Excess Functional Theory
Ezio Bruno, Francesco Mammano, Antonino Fiorino +1
The class of the Generalized Coherent Potential Approximations (GCPA) to the Density Functional Theory (DFT) is introduced within the Multiple Scattering Theory formalism for deali…
Effects of short-range order on the electronic structure of disordered metallic systems
Derwyn A. Rowlands, Julie B. Staunton, Balazs L. Gyorffy +2
For many years the Korringa-Kohn-Rostoker coherent-potential approximation (KKR-CPA) has been widely used to describe the electronic structure of disordered systems based upon a fi…
Temperature dependent magnetic anisotropy in metallic magnets from an ab-initio electronic structure theory: L1_0-ordered FePt
J. B. Staunton, S. Ostanin, S. S. A. Razee +4
On the basis of a first-principles, relativistic electronic structure theory of finite temperature metallic magnetism, we investigate the variation of magnetic anisotropy, K, with…
