Geometric Spin Rotation in Triangular Antiferromagnets
Grigor Adamyan, Bastian Pradenas, Boris Ivanov +1
We describe a geometric phenomenon in which a traveling wave made of degenerate Goldstone modes leaves behind a transformed ground state. In a triangular Heisenberg antiferromagnet…
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…
Helical edge modes in a triangular Heisenberg antiferromagnet
Bastian Pradenas, Grigor Adamyan, Oleg Tchernyshyov
We investigate the emergence of helical edge modes in a Heisenberg antiferromagnet on a triangular lattice, driven by a topological mechanism similar to that proposed by Dong et al…
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…
