Unconventional Thermal Magnon Hall Effect in a Ferromagnetic Topological Insulator
Christian Moulsdale, Pierre A. Pantaleón, Ramon Carrillo-Bastos +1
We present theoretically the thermal Hall effect of magnons in a ferromagnetic lattice with a Kekulé-O coupling (KOC) modulation and a Dzyaloshinskii-Moriya interaction (DMI). Thro…
The effects of three magnons interactions in the magnon-density waves of triangular spin lattices
M. Merdan, Y. Xian
We investigate the magnon-density waves proposed as the longitudinal excitations in triangular lattice antiferromagnets by including the cubic and quartic corrections in the large-…
Edge states in a ferromagnetic honeycomb lattice with armchair boundaries
Pierre A. Pantaleón, Yang Xian
We investigate the properties of magnon edge states in a ferromagnetic honeycomb lattice with armchair boundaries. In contrast with fermionic graphene, we find novel edge states du…
Longitudinal Excitations in Bipartite and Hexagonal Antiferromagnetic Spin Lattices
Y. Xian, M. Merdan
Based on our recently proposed magnon-density-waves using the microscopic many-body approach, we investigate the longitudinal excitations in quantum antiferromagnets by including t…
A variational Jastrow coupled-cluster theory of quantum many-body systems
Y. Xian
We study many-body correlations in the ground states of a general quantum system of bosons or fermions by including an additional Jastrow function in our ecently proposed variation…
Excited states of quantum many-body interacting systems: A variational coupled-cluster description
Y. Xian
We extend recently proposed variational coupled-cluster method to describe excitation states of quantum many-body interacting systems. We discuss, in general terms, both quasiparti…
