Heavy-fermion hybridization waves from Dirac spinons near a Kondo-breakdown quantum phase transition
Pedro M. Cônsoli, Matthias Vojta, Onur Erten
Motivated by the recent observation of spatially modulated screening in different paramagnetic heavy-fermion materials, we propose a theoretical mechanism for the emergence of such…
Unveiling Magnetic Frustration via the Elastocaloric Effect
Eric C. Andrade, Pedro M. Cônsoli, Matthias Vojta
Motivated by experimental progress in pressure and strain tuning of quantum materials, we examine the thermodynamic response of frustrated magnets to uniaxial strain. Specifically,…
Fractionalization, emergent SU() symmetries, and fragmentation in layered quantum spin-orbital models
Pedro M. Cônsoli, Aayush Vijayvargia, Onur Erten
We propose a family of layered quantum spin-orbital models as a platform to study fractionalization, unconventional forms of symmetry-breaking order, and their possible coexistence…
Tuning the magnetic properties of Kitaev materials via the antiferromagnetic proximity effect: Novel phases and application to an -RuCl/MnPS bilayer
Pedro M. Cônsoli, Ezra Day-Roberts, Johannes Knolle +2
In recent years, the increasing level of control over van der Waals (vdW) heterostructures has opened new routes to tune the properties of quantum materials. Motivated by these dev…
Ferrimagnetism from quantum fluctuations in Kitaev materials
Niccolò Francini, Pedro M. Cônsoli, Lukas Janssen
Ferrimagnetism appears in the temperature-field phase diagrams of several candidate Kitaev materials, such as the honeycomb cobaltates NaCoTeO and NaCoSbO.…
SU() altermagnetism: Lattice models, magnon modes, and flavor-split bands
Pedro M. Cônsoli, Matthias Vojta
Altermagnetism, a type of magnetic order that combines properties of ferro- and antiferromagnets, has stirred great interest lately not only as a promising source of spintronics ap…
Disorder effects in spiral spin liquids: Long-range spin textures, Friedel-like oscillations, and spiral spin glasses
Pedro M. Cônsoli, Matthias Vojta
Spiral spin liquids are correlated states of matter in which a frustrated magnetic system evades order by fluctuating between a set of (nearly) degenerate spin spirals. Here, we in…
Kondo breakdown transitions and phase-separation tendencies in valence-fluctuating heavy-fermion materials
Pedro M. Cônsoli, Matthias Vojta
The breakdown of the lattice Kondo effect in local-moment metals can lead to non-trivial forms of quantum criticality and a variety of non-Fermi-liquid phases. Given indications th…
Stability of ordered and disordered phases in the Heisenberg-Kitaev model in a magnetic field
Pedro M. Cônsoli, Eric C. Andrade
The Kitaev honeycomb model has attracted significant attention as an exactly solvable example with a quantum spin liquid ground state. In a properly oriented external magne…
Fluctuation-induced ferrimagnetism in sublattice-imbalanced antiferromagnets with application to SrCu(BO) under pressure
Pedro M. Cônsoli, Max Fornoville, Matthias Vojta
We show that a collinear Heisenberg antiferromagnet, whose sublattice symmetry is broken at the Hamiltonian level, becomes a fluctuation-induced ferrimagnet at any finite temperatu…
Heisenberg-Kitaev model in a magnetic field: expansion
Pedro M. Cônsoli, Lukas Janssen, Matthias Vojta +1
The exact solution of Kitaev's spin- honeycomb spin-liquid model has sparked an intense search for Mott insulators hosting bond-dependent Kitaev interactions, of which $\mathr…
Field-induced phase transitions of the Kitaev material -RuCl probed by thermal expansion and magnetostriction
S. Gass, P. M. Cônsoli, V. Kocsis +8
High-resolution thermal expansion and magnetostriction measurements were performed on single crystals of -RuCl in magnetic fields applied parallel to the Ru-Ru bonds. The le…
A consistent derivation of the quark--antiquark and three quark potentials in a Wilson loop context
N. Brambilla, P. Consoli, G. M. Prosperi
In this paper we give a new derivation of the quark-antiquark potential in the Wilson loop context. This makes more explicit the approximations involved and enables an immediate ex…
