Paradigm for finding d-electron heavy fermions: the case of Cr-doped CsFeAs
Matteo Crispino, Pablo Villar Arribi, Anmol Shukla +8
We define a general strategy for finding new heavy-fermionic materials without rare-earth elements: doping a Hund metal with pronounced orbital-selective correlations towards half-…
Bicircular light tuning of magnetic symmetry and topology in Dirac semimetal CdAs
Thaís V. Trevisan, Pablo Villar Arribi, Olle Heinonen +2
We show that Floquet engineering using bicircular light (BCL) is a versatile way to control magnetic symmetries and topology in materials. The electric field of BCL, which is a sup…
Hund's metal crossover and superconductivity in the 111 family of iron-based superconductors
Pablo Villar Arribi, Luca de' Medici
We study LiFeP, LiFeAs and NaFeAs in their paramagnetic metallic phase including dynamical electronic correlations within a density functional theory + slave-spin mean-field framew…
Enhancement of charge instabilities in Hund's metals by the breaking of rotational symmetry
Maria Chatzieleftheriou, Maja Berović, Pablo Villar Arribi +2
We analyze multi-orbital Hubbard models describing Hund's metals, focusing on the ubiquitous occurrence of a charge instability, signalled by a divergent/negative electronic compre…
A Striped Electron Fluid on (111) KTaO
P. Villar Arribi, A. Paramekanti, Michael R. Norman
A recent study has revealed that the low carrier density electron gas (2DEG) induced at the interface of EuO and (111) KTaO exhibits a broken symmetry phase with a strong in-pl…
Magnetic competition in iron-based germanide and silicide superconductors
P. Villar Arribi, F. Bernardini, L. de'Medici +3
We address the ferromagnetic tendencies detrimental for superconductivity that are related to the substitution of the pnictogen As atom with Ge or Si, together with additional subs…
Efficient thermoelectric materials using nonmagnetic double perovskites with / band filling
Pablo Villar Arribi, Pablo García-Fernández, Javier Junquera +1
Efficient thermoelectric materials should present large Seebeck coefficient, high electrical conductivity and low thermal conductivity. An enhanced Seebeck coefficient can be obtai…
