SO(4) FLEX+DMFT formalism with SU(2)SU(2)-symmetric impurity solver for superconductivity in the repulsive Hubbard model
Sharareh Sayyad, Naoto Tsuji, Massimo Capone +1
Here we have developed a FLEX+DMFT formalism, where the symmetry properties of the system are incorporated by constructing a SO(4) generalization of the conventional fluctuation-ex…
Nematicity at the Hund's metal crossover in iron superconductors
L. Fanfarillo, G. Giovannetti, M. Capone +1
The theoretical understanding of the nematic state of iron-based superconductors and especially of FeSe is still a puzzling problem. Although a number of experiments calls for a pr…
Strong Correlations, Strong Coupling and s-wave Superconductivity in Hole-doped BaFe2As2 Single Crystals
F. Hardy, A. E. Böhmer, L. de' Medici +12
We present a comprehensive study of the low-temperature heat capacity and thermal expansion of single crystals of the hole-doped Ba1-xKxFe2As2 series (0<x<1) and the end-members Rb…
Ultrafast optical spectroscopy of strongly correlated materials and high-temperature superconductors: a non-equilibrium approach
Claudio Giannetti, Massimo Capone, Daniele Fausti +3
In the last two decades, non-equilibrium spectroscopies have evolved from avant-garde studies to crucial tools for expanding our understanding of the physics of strongly correlated…
Transient Dynamics of d-wave Superconductors after a Sudden Excitation
Francesco Peronaci, Marco Schirò, Massimo Capone
Motivated by recent ultafast pump probe experiments on high-temperature superconductors, we discuss the transient dynamics of a d-wave BCS model after a quantum quench of the inter…
Unified understanding of superconductivity and Mott transition in alkali-doped fullerides from first principles
Yusuke Nomura, Shiro Sakai, Massimo Capone +1
Alkali-doped fullerides A3C60 (A=K, Rb, Cs) are surprising materials where conventional phonon-mediated superconductivity and unconventional Mott physics meet, leading to a remarka…
Electronic correlations stabilize the antiferromagnetic Mott state in CsC
G. Giovannetti, M. Capone
CsC in the A15 structure is an antiferromagnet at ambient pressure in contrast with other superconducting trivalent fullerides. Superconductivity is recovered under pres…
Proximity of Iron Pnictide Superconductors to a Quantum Tricritical Point
G. Giovannetti, C. Ortix, M. Marsman +3
We determine the nature of the magnetic quantum critical point in the doped LaFeAsO using a set of constrained density functional calculations that provide ab initio coefficients f…
On the possible secondary component of the order parameter observed in London penetration depth measurements
Angelo Valli, Giorgio Sangiovanni, Massimo Capone +1
We discuss the effect of a secondary component of the superconducting order parameter on the superfluid density in the cuprates. If we assume a main gap, the most sta…
Modeling the Unconventional Superconducting Properties of Expanded AC Fullerides
M. Capone, M. Fabrizio, C. Castellani +1
The trivalent alkali fullerides AC, where C are a well established family of molecular superconductors. The electron pairing has s-wave symmetry and is due to sta…
Polarized superfluidity in the attractive Hubbard model with population imbalance
Tung-Lam Dao, Michel Ferrero, Antoine Georges +2
We study a two-component Fermi system with attractive interactions and different populations of the two species in a cubic lattice. For an intermediate coupling we find a uniformly…
Strongly Correlated Superconductivity rising from a Pseudo-gap Metal
Marco Schiro', Massimo Capone, Michele Fabrizio +1
We solve by Dynamical Mean Field Theory a toy-model which has a phase diagram strikingly similar to that of high superconductors: a bell-shaped superconducting region adjacen…
Competing superfluid and density-wave ground-states of fermionic mixtures with mass imbalance in optical lattices
Tung-Lam Dao, Antoine Georges, Massimo Capone
We study the effect of mass imbalance on the phase diagram of a two-component fermionic mixture with attractive interactions in optical lattices. Using static and dynamical mean-fi…
