Infinite coherence time of edge spins in finite-length chains
Ivo Maceira, Frédéric Mila
Motivated by the recent observation that exponentially long coherence times can be achieved for edge spins in models with strong zero modes, we study the impact of level crossings…
Linear Flavor-Wave Theory for Fully Antisymmetric Irreducible Representations
Francisco Hyunkyu Kim, Karlo Penc, Pierre Nataf +1
The extension of the linear flavor-wave theory (LFWT) to fully antisymmetric irreducible representations (irreps) of is presented in order to investigate the color…
Numerically exploring the 1D-2D dimensional crossover on spin dynamics in the doped Hubbard model
Y. F. Kung, C. Bazin, K. Wohlfeld +7
Using determinant quantum Monte Carlo (DQMC) simulations, we systematically study the doping dependence of the crossover from one to two dimensions and its impact on the magnetic p…
Microscopic theory of the nearest-neighbor valence bond sector of the spin-1/2 kagome antiferromagnet
Arnaud Ralko, Frédéric Mila, Ioannis Rousochatzakis
The spin-1/2 Heisenberg model on the kagome lattice, which is closely realized in layered Mott insulators such as ZnCu(OH)Cl, is one of the oldest and most enigmatic sp…
Spin-liquid behaviour and the interplay between Pokrovsky-Talapov and Ising criticality in the distorted, triangular-lattice, dipolar Ising antiferromagnet
Andrew Smerald, Frederic Mila
We study the triangular-lattice Ising model with dipolar interactions, inspired by its realisation in artificial arrays of nanomagnets. We show that a classical spin-liquid forms a…
Exact diagonalization of Heisenberg and AKLT chains using the full symmetry
Kianna Wan, Pierre Nataf, Frédéric Mila
We present a method for the exact diagonalization of the Heisenberg interaction Hamiltonian, using Young tableaux to work directly in each irreducible representati…
