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…
Quantum spin-glass criticality in disordered frustrated dimer magnets
Darshan G. Joshi, Matthias Vojta
We study quantum phase transitions of Mott insulators between spin-glass and featureless paramagnetic phases. Specifically, we consider a triangular-lattice bilayer Heisenberg mode…
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,…
Field-driven phases in a three-dimensional twisted Kitaev model for CoNbO: Interplay of frustration and spin-orbit coupling
Tom Drechsler, Matthias Vojta
The Ising chain in a transverse field stands out as a paradigmatic example for a quantum phase transition. CoNbO has been discussed as a material realization of this physic…
Quantum Coulomb Liquids of Different Rank in the Breathing Pyrochlore Antiferromagnet
Lasse Gresista, Daniel Lozano-Gómez, Matthias Vojta +2
Emergent gauge fields and Coulomb liquids have long been central to the physics of frustrated pyrochlore magnets, yet their realization beyond conventional, i.e. rank-1 , spi…
