Matrix Product Belief Propagation
Gabriel Woolls, Shahin Jahanbani, Adarsh Pashikanti +3
We introduce "matrix product belief propagation" (MP-BP) as a controlled method for the approximate contraction of two-dimensional tensor networks and graphical models, which gener…
Local spectroscopy of anyons bound to charge traps
Jeong Min Park, Cristian Voinea, Yen-Chen Tsui +7
Fractional quantum Hall states host anyons, emergent quasiparticles with fractional charge and nontrivial exchange statistics. Controlling, trapping, and braiding anyons are centra…
Imaging Interacting Two-Dimensional Anisotropic Electrons
Ziyu Xiang, Jianghan Xiao, Hongyuan Li +9
We directly visualize a two-dimensional anisotropic Wigner crystal and its quantum melting in monolayer 1T-ReSe2 using non-invasive scanning tunnelling microscopy. In crystals with…
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…
Tunable Interlayer Charge-transfer States in MoSe/WS Moiré Superlattices
Zheyu Lu, Jiahui Nie, Tianle Wang +15
Moiré superlattices formed by transition metal dichalcogenide (TMD) heterobilayers provide a versatile platform for studying strongly correlated electronic, excitonic, and topologi…
Self-doped Crystal from Preempted Band-inversion Transitions
Jiechao Feng, Zhaoyu Han, Michael P. Zaletel +1
Recent experiments in rhombohedral graphene find evidence for a "self-doped" Wigner crystal (SDC) in which a slightly incommensurate Wigner crystal (WC) coexists with a small Fermi…
Anyon molecules in fractional quantum Hall states
Taige Wang, Michael P. Zaletel
We use segment DMRG on the infinite cylinder to compute energies of charged excitations in gate-screened fractional quantum Hall states. For the Laughlin, Jain, and…
A Dipolar Chiral Spin Liquid on the Breathed Kagome Lattice
Francisco Machado, Sabrina Chern, Michael P. Zaletel +1
Continuous control over lattice geometry, when combined with long-range interactions, offers a powerful yet underexplored tool to generate highly frustrated quantum spin systems. B…
Robustness of Kardar-Parisi-Zhang-like transport in long-range interacting quantum spin chains
Sajant Anand, Jack Kemp, Julia Wei +3
Isotropic integrable spin chains such as the Heisenberg model feature superdiffusive spin transport belonging to an as-yet-unidentified dynamical universality class closely related…
Imaging Electron-Hole Asymmetry in the Quantum Melting of Generalized Wigner Crystals
Emma Berger, Michael Arumainayagam, Zhihuan Dong +12
Two-dimensional moiré materials provide a versatile platform to explore phase transitions in strongly correlated systems. Using scanning tunneling microscopy (STM) we have imaged t…
Visualizing interaction-driven restructuring of quantum Hall edge states
Jiachen Yu, Haotan Han, Kristina G. Wolinski +10
Many topological phases host gapless boundary modes that can be dramatically modified by electronic interactions. Even for the long-studied edge modes of quantum Hall phases, formi…
Robust superconductivity upon doping chiral spin liquid and Chern insulators in a Hubbard-Hofstadter model
Clemens Kuhlenkamp, Stefan Divic, Michael P. Zaletel +2
Demonstrating superconductivity in purely repulsive Hubbard models is a compelling goal which underscores the counter-intuitive ability of Coulomb interactions to mediate supercond…
Anyon superfluidity of excitons in quantum Hall bilayers
Zhaoyu Han, Taige Wang, Zhihuan Dong +2
The charged anyons of a fractional quantum Hall fluid are necessarily dispersionless due to the continuous magnetic translation symmetry. Neutral anyons, however, can disperse, res…
Chiral superconductivity near a fractional Chern insulator
Taige Wang, Michael P. Zaletel
Superconductivity arising from fully spin-polarized, repulsively interacting electrons can host intrinsically chiral Cooper pairs and Majorana zero modes, yet no concrete microscop…
Majorana edge reconstruction and the non-Abelian thermal Hall puzzle
Tevž Lotrič, Taige Wang, Michael P. Zaletel +2
Pioneering thermal transport measurements on two-dimensional electron gases in high magnetic fields have demonstrated that the quantized Hall state at filling factor has a…
Diagonal Isometric Form for Tensor Network States in Two Dimensions
Benjamin Sappler, Masataka Kawano, Michael P Zaletel +1
Isometric tensor network states (isoTNS) generalize the isometric form of the one-dimensional matrix product states (MPS) to tensor networks in two and higher dimensions. Here, we…
Emergent QED at the bosonic Laughlin state to superfluid transition
Taige Wang, Xue-Yang Song, Michael P. Zaletel +1
Quantum phase transitions between topologically ordered and symmetry-broken phases lie beyond Landau theory. A prime example is the conjectured continuous transition from the boson…
Alternating and Gaussian fermionic Isometric Tensor Network States
Yantao Wu, Zhehao Dai, Sajant Anand +5
Isometric tensor networks in two dimensions enable efficient and accurate study of quantum many-body states, yet the effect of the isometric restriction on the represented quantum…
