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…
Strong Correlation Driven Quadrupolar to Dipolar Exciton Transitions in a Trilayer Moiré Superlattice
Yuze Meng, Lei Ma, Li Yan +13
The additional layer degree of freedom in trilayer moiré superlattices of transition metal dichalcogenides enables the emergence of novel excitonic species, such as quadrupolar exc…
Spin-orbital magnetism in moiré Wigner molecules
Ahmed Khalifa, Rokas Veitas, Francisco Machado +1
The interplay of spin and orbital degrees of freedom offers a versatile playground for the realization of a variety of correlated phases of matter. However, the types of spin-orbit…
Field-induced magnon decays in dipolar quantum magnets
Andrew D. Kim, Ahmed Khalifa, Shubhayu Chatterjee
We investigate the spontaneous disintegration of magnons in two-dimensional ferromagnets and antiferromagnets dominated by long-range dipolar interactions. Analyzing kinematic cons…
Dirac spin liquid in quantum dipole arrays
Marcus Bintz, Vincent S. Liu, Johannes Hauschild +4
We predict that the gapless Dirac spin liquid naturally emerges in a two-dimensional array of quantum dipoles. In particular, we demonstrate that the dipolar XY model$\unico…
