Absorbing Many-Body Correlations into Core-Optimized Orbitals
Hao Zhang, Matthew Otten
The cost of simulating quantum many-body systems - on classical or quantum hardware - scales with the number of variational parameters, so progress at fixed computational budget hi…
Quantized SO(3)-Equivariant Graph Neural Networks for Efficient Molecular Property Prediction
Haoyu Zhou, Ping Xue, Hao Zhang +1
Deploying 3D graph neural networks (GNNs) that are equivariant to 3D rotations (the group SO(3)) on edge devices is challenging due to their high computational cost. This paper add…
Direct imaging of a Berry curvature nematic state in a spin-compensated magnet
Weihang Lu, Camron Farhang, Yuchuan Yao +6
Density waves conventionally describe the periodic modulation of charge or spin, yet the spatial modulation of electronic geometry has remained elusive. Here, we report subtle micr…
High-resolution wide-field magnetic imaging with sparse sampling using nitrogen-vacancy centers
Keqing Liu, Jiazhao Tian, Bokun Duan +7
Nitrogen-vacancy (NV) centers in diamond enable quantitative magnetic imaging, yet practical implementations must balance spatial resolution against acquisition time (and thus per-…
Kitaev interactions in the van der Waals antiferromagnet VBr3
Zeyu Kao, Yimeng Gu, Yiqing Gu +5
Van der Waals materials hosting Kitaev interactions are promising platforms for exploring exotic quantum phenomena. Here, we report inelastic neutron scattering investigations of t…
From Random Determinants to the Ground State
Hao Zhang, Matthew Otten
Accurate quantum many-body calculations often depend on reliable reference states or good human-designed ansätze, yet these sources of knowledge can become unreliable in hard probl…
CycleChemist: A Dual-Pronged Machine Learning Framework for Organic Photovoltaic Discovery
Hou Hei Lam, Jiangjie Qiu, Xiuyuan Hu +5
Organic photovoltaic (OPV) materials offer a promising path toward sustainable energy generation, but their development is limited by the difficulty of identifying high performance…
Strongly Entangled Kondo and Kagome Lattices and the Emergent Magnetic Ground State in Heavy-Fermion Kagome Metal YbVSn
Rui Lou, Max Mende, Riccardo Vocaturo +31
Applying angle-resolved photoemission spectroscopy and density functional theory calculations, we present compelling spectroscopic evidence demonstrating the intertwining and mutua…
Cyclic Variational Quantum Eigensolver: Escaping Barren Plateaus through Staircase Descent
Hao Zhang, Ayush Asthana
We introduce the Cyclic Variational Quantum Eigensolver (CVQE), a hardware-efficient framework for accurate ground-state quantum simulation on noisy intermediate-scale quantum (NIS…
Nonperturbative Semiclassical Spin Dynamics for Ordered Quantum Magnets
Hao Zhang, Tianyue Huang, Allen O. Scheie +7
In ordered quantum magnets where interactions between elementary excitations dominate over their kinetic energy, perturbative approaches often fail, making non-perturbative methods…
Universal dynamics of a pair condensate
Qing Huang, Hao Zhang, Yiqing Hao +10
Pair condensates appear in multiple branches of physics, always introducing exotic phenomena. The pair condensate in quantum magnetism is the spin nematic, whose static (quadrupola…
Non-linear magnons and exchange Hamiltonians of delafossite proximate quantum spin liquids
A. O. Scheie, Y. Kamiya, Hao Zhang +20
Quantum spin liquids (QSL) are theoretical states of matter with long-range entanglement and exotic quasiparticles. However, they generally elude quantitative theory, rendering the…
Spin Transport in a Mott Insulator of Ultracold Fermions
Matthew A. Nichols, Lawrence W. Cheuk, Melih Okan +6
Strongly correlated materials are expected to feature unconventional transport properties, such that charge, spin, and heat conduction are potentially independent probes of the dyn…
