Triangular lattice Majorana-Hubbard model: Mean field theory and DMRG on a width-4 torus
Tarun Tummuru, Alberto Nocera, Ian Affleck
Majorana modes can arise as zero energy bound states in a variety of solid state systems. A two-dimensional phase supporting these quasiparticles, for instance, emerges on the surf…
Bipolaron liquids at strong Peierls electron-phonon couplings
Alberto Nocera, John Sous, Adrian E. Feiguin +1
We use the Density Matrix Renormalization Group method to study a one-dimensional chain with Peierls electron-phonon coupling, which describes the modulation of the electron hoppin…
Spin wave theory of one-dimensional generalized Kitaev model
Wang Yang, Alberto Nocera, Ian Affleck
In this work, we perform a combination of classical and spin wave analysis on the one-dimensional spin- Kitaev-Heisenberg-Gamma model in the region of an antiferromagnetic Kitae…
Spectroscopic signatures of next-nearest-neighbor hopping in the charge and spin dynamics of doped one-dimensional antiferromagnets
Umesh Kumar, Gregory Price, Kenneth Stiwinter +3
We study the impact of next-nearest-neighbor (nnn) hopping on the low-energy collective excitations of strongly correlated doped antiferromagnetic cuprate spin chains. Specifically…
Comprehensive study of the phase diagram of the spin-1/2 Kitaev-Heisenberg-Gamma chain
Wang Yang, Alberto Nocera, Ian Affleck
A central question on Kitaev materials is the effects of additional couplings on the Kitaev model which is proposed to be a candidate for realizing topological quantum computations…
Classical spin order near antiferromagnetic Kitaev point in the spin-1/2 Kitaev-Gamma chain
Wang Yang, Alberto Nocera, Erik S. Sørensen +2
A minimal Kitaev-Gamma model has been recently investigated to understand various Kitaev systems. In the one-dimensional Kitaev-Gamma chain, an emergent SU(2) phase and a rank-…
