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…
