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…
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…
Compton Form Factor Extraction using Quantum Deep Neural Networks
Brandon B. Le, Dustin Keller
We extract Compton form factors (CFFs) from deeply virtual Compton scattering measurements at the Thomas Jefferson National Accelerator Facility (JLab) using quantum-inspired deep…
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 $(ÎB,ÎL)…
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…
