Spontaneous symmetry breaking in the Heisenberg antiferromagnet on a triangular lattice
Bastián Pradenas, Grigor Adamyan, Oleg Tchernyshyov
We present a detailed investigation of an overlooked symmetry structure in non-collinear antiferromagnets that gives rise to an emergent quantum number for magnons. Focusing on the…

Conformal maps and edge mode attenuation on imperfect boundaries
Grigor Adamyan
We developed a conformal map technique to analyze the attenuation of edge modes propagating along imperfect boundaries. In systems where the potential energy exhibits conformal inv…

Hofstadter quasicrystals, hidden symmetries and irrational quantum oscillations
Kirill Kozlov, Grigor Adamyan, Mariia Kryvoruchko +2
Landau levels perturbed by a periodic potential is a prime setting to design quantum systems with exotic fractal spectra. Motivated by recent advances in twistronics, we introduce…
