Topological and magnetic phase transitions in the bilayer Kitaev-Ising model
Aayush Vijayvargia, Urban F. P. Seifert, Onur Erten
We investigate the phase diagram of a bilayer Kitaev honeycomb model with Ising interlayer interactions, deriving effective models via perturbation theory and performing Majorana m…
Theory of moiré magnetism in twisted bilayer -RuCl
Muhammad Akram, Jesse Kapeghian, Jyotirish Das +3
Twisted heterostructures of van der Waals materials have received much attention for their many remarkable properties. Here, we present a comprehensive theory of the long-range ord…
A Kitaev-type spin liquid on a quasicrystal
M. A. Keskiner, O. Erten, M. Ö. Oktel
We develop an exactly solvable model with Kitaev-type interactions and study its phase diagram on the dual lattice of the quasicrystalline Ammann-Beenker lattice. Our construction…
Revival of antibiskyrmionic magnetic phases in bilayer NiI
Jyotirish Das, Muhammad Akram, Onur Erten
Magnetic skyrmions are topologically protected spin textures with potential applications in memory and logic devices. Skyrmions have been commonly observed in systems with Dzyalosh…
Vison crystals, chiral and crystalline phases in the Yao-Lee model
Muhammad Akram, Emilian Marius Nica, Yuan-Ming Lu +1
We study the phase diagram of the Yao-Lee model with Kitaev-type spin-orbital interactions in the presence of Dzyaloshinskii-Moriya interactions and external magnetic fields. Unlik…
Magnetic fragmentation and fractionalized Goldstone modes in a bilayer quantum spin liquid
Aayush Vijayvargia, Emilian Marius Nica, Roderich Moessner +2
We study the phase diagram of a bilayer quantum spin liquid model with Kitaev-type interactions on a square lattice. We show that the low energy limit is described by a -flux Hu…
