Quantum Entanglement of Anyonic Charges and Emergent Spacetime Geometry
Hoang-Anh Le, Hyun Cheol Lee, S. -R. Eric Yang
Intrinsically topologically ordered phases can host anyons. Here, we take the view that entanglement between anyons can give rise to an emergent geometry resembling Anti-de Sitter…
On flat bands in the -- XXZ sawtooth chain
Vadim Ohanyan, Johannes Richter, Michael Sekania +3
We consider a generalization of the XXZ model on the sawtooth spin chain with Dzyaloshinskii-Moriya interactions in which all exchange constants (symmetric, antisymmetric, and axia…
Thermodynamic theory of square skyrmion lattice in tetragonal frustrated antiferromagnets
Oleg I. Utesov, Danila P. Budylev
High-temperature part of the phase diagram of tetragonal frustrated antiferromagnets is discussed within the framework of the mean-field approach. Based on recent experimental find…
Spin liquid state in a three-dimensional pyrochlore-like frustrated magnet
U. Jena, S. Kundu, Suheon Lee +7
The three-dimensional frustrated spin lattice in MgCrGaO4, where Cr3+ ions occupy a pyrochlore-like network, exemplifies a quantum magnet with competing interactions, macroscopic d…
Helical spin dynamics in CuOSeO as measured with small-angle neutron scattering
Victor Ukleev, Priya R. Baral, Robert Cubitt +3
The insulating chiral magnet CuOSeO exhibits a rich array of low-temperature magnetic phenomena, making it a prime candidate for the study of its spin dynamics. Using spin…
Coexistence of static and dynamic local magnetic fields in an S = 3/2 honeycomb lattice antiferromagnet Co2Te3O8
J. Khatua, Suheon Lee, M. Pregelj +7
Two-dimensional honeycomb lattices, characterized by their low coordination numbers, provide a fertile platform for exploring various quantum phenomena due to the intricate interpl…
