Continuum neural wavefunctions for anyons on a torus
Ahmed Khalifa, Shubhayu Chatterjee
Mobile anyons in topologically ordered phases provide a setting to investigate how fractional exchange statistics shapes collective behavior at finite density. We introduce AnyForm…
From continuum neural quantum states to effective lattice models: Fluctuating Wigner molecules in moiré superlattices
Ahmed Khalifa, Shubhayu Chatterjee
Effective descriptions of quantum materials rely on a separation of energy scales that identifies their low-energy degrees of freedom. When kinetic energy, lattice potential, and i…
Fluctuation-driven chiral ferromagnetism
Rokas Veitas, Ahmed Khalifa, Francisco Machado +1
Quantum fluctuations are often suppressed in ferromagnetic materials because they admit a simple unfrustrated ground state, greatly limiting the scope of the phenomena that can be…
Ground states of quantum XY dipoles on the Archimedean lattices
Marcus Bintz, Ahmed Khalifa, Vincent S. Liu +4
We report numerical ground states for the dipolar XY spin model, which describes extended antiferromagnetic interactions in two-dimensional arrays of polar molecules and two-level…
