Kitaev honeycomb antiferromagnet in a field: quantum phase diagram for general spin
Saeed S. Jahromi, Max Hörmann, Patrick Adelhardt +4
We combine tensor-network approaches and high-order linked-cluster expansions to investigate the quantum phase diagram of the antiferromagnetic Kitaev's honeycomb model in a magnet…
Frustrated mixed-spin ladders: Evidence for a bond order wave phase between rung-singlet and Haldane phases
N. Ahmadi, J. Abouie, R. Haghshenas +1
In frustrated spin ladders the interplay of frustration and correlations leads to the familiar Haldane (H) and rung-singlet (RS) phases. The nature of the transition between these…
Dynamical Topological Quantum Phase Transitions at Criticality
M. Sadrzadeh, R. Jafari, A. Langari
The nonequilibrium dynamics of two dimensional Su-Schrieffer-Heeger model, in the presence of staggered chemical potential, is investigated using the notion of dynamical quantum ph…
Strongly anisotropic spin dynamics in magnetic topological insulators
A. Alfonsov, J. I. Facio, K. Mehlawat +8
The recent discovery of magnetic topological insulators has opened new avenues to explore exotic states of matter that can emerge from the interplay between topological electronic…
Topological line in frustrated Toric code models
M. H. Zarei, J. Abouie
Typical topological systems undergo a topological phase transition in the presence of a strong enough perturbation. In this paper, we propose an adjustable frustrated Toric code wi…
