Instabilities of the Fractionalized Dirac Semimetal in the Kitaev-Kondo Model

Jennifer Lin, Frank Krüger

We study a honeycomb Kondo lattice model in which Dirac conduction electrons are coupled to a spin-1/2 Kitaev quantum spin liquid. For weak Kondo coupling, the spins fractionalize…

Nature of the Topological Transition of the Kitaev Model in [111] Magnetic Field

S. Thiagarajan, C. Watson, T. Yzeiri +3

We investigate the nature of the topological phase transition of the antiferromagnetic Kitaev model on the honeycomb lattice in the presence of a magnetic field along the [111] dir…

Magnetic hard-direction ordering in anisotropic Kondo systems

M. P. Kwasigroch, Huanzhi Hu, F. Krüger +1

We present a generic mechanism that explains why many Kondo materials show magnetic ordering along directions that are not favoured by the crystal-field anisotropy. Using a renorma…

Hidden Charge Order of Interacting Dirac Fermions on the Honeycomb Lattice

Elliot Christou, Bruno Uchoa, Frank Krüger

We consider the extended half-filled Hubbard model on the honeycomb lattice for second nearest neighbors interactions. Using a functional integral approach, we find that collective…

Phase diagram of the frustrated, spatially anisotropic S=1 antiferromagnet on a square lattice

H. C. Jiang, F. Krüger, J. E. Moore +3

We study the S=1 square lattice Heisenberg antiferromagnet with spatially anisotropic nearest neighbor couplings , frustrated by a next-nearest neighbor coupling $…

Magnetic fluctuations in n-type high- superconductors reveal breakdown of fermiology

F. Krüger, S. D. Wilson, L. Shan +6

By combining experimental measurements of the quasiparticle and dynamical magnetic properties of optimally electron-doped PrLaCeCuO with theoretical calculati…
