Dynamical signatures of deconfined spinons in dimerized sawtooth chains
Nishan Ranabhat, Brandon B. Le, Seung-Hun Lee +1
We study the ground-state properties and dynamical response of the Heisenberg model on the sawtooth chain in and away from the exactly solvable valence-bond-solid (VBS) point. We e…
Frustrated neurons: Energy landscapes and relaxation dynamics in repulsive phase oscillators
Brandon B. Le
Geometrical frustration, a central paradigm in condensed matter physics, provides a unifying language for systems in which locally preferred interactions cannot be made globally co…
Schwinger-Boson Mean-Field Study of the Anisotropic Kagome Antiferromagnet
Sankha Subhra Bakshi, Brandon B. Le, Seung-Hun Lee +1
We investigate the effect of spatial exchange anisotropy on the spin- kagome antiferromagnet using Schwinger-boson mean-field theory. The anisotropy is introduced by strengthe…
Basis for non-derivative baryon-number-violating operators
Julian Heeck, Brandon B. Le
We present a minimal basis for non-derivative baryon-number-violating operators in the Standard Model Effective Field Theory up to mass dimension 11, as well as for the $(ΔB,ΔL) =…
Active-learning mapping of the Vicsek model phase diagram
Grace T. Bai, Brandon B. Le
The Vicsek model is a minimal model of collective motion, capturing how local alignment interactions can generate macroscopic nonequilibrium order in systems such as bird flocks. I…
Energy landscape of the kagome antiferromagnet: Characterization of multiple energy scales
Brandon B. Le, Seung-Hun Lee, Gia-Wei Chern
We investigate the energy landscape of the kagome Heisenberg antiferromagnet within its coplanar ground-state manifold. Although coplanar states are degenerate at harmonic order, t…
