Order Fractionalization in a Kitaev-Kondo model
Alexei M. Tsvelik, Piers Coleman
We describe a mechanism for order fractionalization in a two-dimensional Kondo lattice model, in which electrons interact with a gapless spin liquid of Majorana fermions described…
Triplet resonating valence bond theory and transition metal chalcogenides
Elio J. König, Yashar Komijani, Piers Coleman
We develop a quantum spin liquid theory for quantum magnets with easy-plane ferromagnetic exchange. These strongly entangled quantum states are obtained by dimer coverings of 2D la…
Information-theoretic measures of superconductivity in a two-dimensional doped Mott insulator
C. Walsh, M. Charlebois, P. Sémon +2
A key open issue in condensed matter physics is how quantum and classical correlations emerge in an unconventional superconductor from the underlying normal state. We study this pr…
Spin dynamics of the director state in frustrated hyperkagome systems
Henrik Jacobsen, Ovidiu Florea, Elsa Lhotel +10
We present an experimental study of the magnetic structure and dynamics of two frustrated hyperkagome compounds, Gd3Ga5O12 and Gd3Al5O12. It has previously been shown that Gd3Ga5O1…
Magnetic field-induced softening of spin waves and hard-axis order in Kondo-lattice ferromagnet CeAgSb
S. E. Nikitin, A. Podlesnyak, J. Xu +5
A significant number of Kondo-lattice ferromagnets order perpendicular to the easy magnetization axis dictated by the crystalline electric field. The nature of this phenomenon has…
Structural and magnetic properties of the new quantum magnet BaCuTeO
A. Samartzis, D. Khalyavin, A. T. M. N. Islam +6
We investigate the structural and magnetic properties of the new quantum magnet BaCuTeO. This compound is synthesized for the first time in powder and single crystal form.…
Emergent moments in a Hund's impurity
Victor Drouin-Touchette, Elio J. König, Yashar Komijani +1
Motivated by the relevance of Hund's coupling in the context of multiorbital superconductors, we revisit the problem of a multiorbital Kondo impurity with Hund's interaction. Using…
