Exact zero modes in frustrated Haldane chains
Natalia Chepiga, Frédéric Mila
We show that the effective coupling between the spin-1/2 edge states of a spin-1 chain of finite length can be continuously tuned by frustration. For the model with neare…

Excitation spectrum and Density Matrix Renormalization Group iterations
Natalia Chepiga, Frédéric Mila
We show that, in certain circumstances, exact excitation energies appear as locally site-independent (or flat) modes if one records the excitation spectrum of the effective Hamilto…

Controlling the topological sector of magnetic solitons in exfoliated CrNbS crystals
L. Wang, N. Chepiga, D. -K. Ki +9
We investigate manifestations of topological order in monoaxial helimagnet CrNbS by performing transport measurements on ultra-thin crystals. Upon sweeping the magnetic…
