Pseudogap phases, chiral anomaly and topological order with quantum loop entanglement
Predrag Nikolić
A many-body quantum system whose topological defects are conserved, abundant and mobile is a correlated quantum liquid. Since topological defects can be classified by homotopy grou…
Instanton confinement-deconfinement transitions: The stability of pseudogap phases and topological order
Predrag Nikolić
We explore the stability of certain many-body quantum states which may exist at zero or finite temperatures, may lack long-range order and even topological order, and still are the…
Weyl-Luttinger phase transition in pyrochlore iridates revealed by Raman scattering
Predrag Nikolić, Yuanyuan Xu, Takumi Ohtsuki +2
Pyrochlore iridates are thought to be a fertile ground for the realization of topologically non-trivial and strongly correlated states of matter. Here we provide a compelling evide…
Universal spin wave damping in magnetic Weyl semimetals
Predrag Nikolić
We analyze the decay of spin waves into Stoner excitations in magnetic Weyl semimetals. The lifetime of a mode is found to have a universal dependence on its frequency and momentum…
The dynamics of local magnetic moments induced by itinerant Weyl electrons
Predrag Nikolić
We derive the effective interactions between local magnetic moments which are mediated by Weyl electrons in magnetic topological semimetals. The resulting spin dynamics is governed…
Incommensurate magnetism mediated by Weyl fermions in NdAlSi
Jonathan Gaudet, Hung-Yu Yang, Santu Baidya +11
Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect, and negative magnetore…
Finite momentum condensate brought on by Zeeman field
Stephen Keeling, Predrag Nikolić
We study superfluid states in a two-dimensional fermionic attractive Hubbard model with Zeeman coupling to an external field. Focusing our attention on singlet pairing in both weak…
Quantum field theory of topological spin dynamics
Predrag Nikolić
We develop a field theory of quantum magnets and magnetic (semi)metals, which is suitable for the analysis of their universal and topological properties. The systems of interest in…
Topological orders of monopoles and hedgehogs: From electronic and magnetic spin-orbit coupling to quarks
Predrag Nikolić
Topological states of matter are, generally, quantum liquids of conserved topological defects. We establish this by constructing and analyzing topological field theories which desc…
Magnetic impurities in Kondo insulators: An application to samarium hexaboride
W. T. Fuhrman, P. Nikolić
Impurities and defects in Kondo insulators can have an unusual impact on dynamics that blends with effects of intrinsic electron correlations. Such crystal imperfections are diffic…
Two-dimensional heavy fermions on the strongly correlated boundaries of Kondo topological insulators
Predrag Nikolić
Samarium hexaboride (SmB), a representative Kondo insulator, has been characterized recently as a likely topological insulator. It is also a material with strong electron corre…
Vortices and vortex states in Rashba spin-orbit-coupled condensates
Predrag Nikolić
The Rashba spin-orbit coupling is equivalent to the finite Yang-Mills flux of a static SU(2) gauge field. It gives rise to the protected edge states in two-dimensional topological…
