From dimensional reduction to tetramerization in mixed ferro-antiferro breathing pyrochlores
Sourin Chatterjee, Kelvin Salou-Smith, Benedikt Schneider +8
We study the spin-1/2 nearest-neighbor Heisenberg model on the breathing pyrochlore lattice in the mixed ferro-antiferromagnetic regime, where one tetrahedral sublattice is antifer…
Composite Fields and Tree Expansions: A Unified Framework for Renormalized Vertex Decompositions
Oleksandr Sulyma, Benedikt Schneider
One-particle irreducible vertices encode renormalized interactions in quantum field theories, but their practical treatment remains challenging due to their high dimensionality and…
Finite-temperature spin diffusion in the two-dimensional XY model
Erik Fitzner, Byungjin Lee, Junhyeok Hur +4
We present a combined theory-experiment study to quantify spin diffusion in the square lattice quantum spin-1/2 XY model at finite temperature. On the theory side, we leverage a re…
Revisiting the - Heisenberg Model on a Triangular Lattice: Quasi-Degenerate Ground States and Phase Competition
Oleksandra Kovalska, Ester Pagès Fontanella, Benedikt Schneider +2
It is generally believed that the spin- triangular-lattice - Heisenberg model hosts a quantum spin liquid in the intermediate regime between the …
