Scaling universal Fermi network toward ground states: A diffusion-Monte-Carlo assessment
Yu-Sheng Li, Saskia Poldmaa, Tzen Ong +4
In this work, we show that Fermi Sets---a provably universal neural network architecture for fermionic wavefunctions---can be systematically scaled up to find interacting ground st…
Emergent Quantum-Geometric Equivalence of Injection and Shift Currents
Mohammad Yahyavi, Tay-Rong Chang, Md Shafayat Hossain +3
Injection and shift currents are generally regarded as distinct nonlinear optical responses with separate microscopic origins. Here, we uncover a general hidden connection between…
Wavefunction-Free Approach for Predicting Nonlinear Responses in Weyl Semimetals
Mohammad Yahyavi, Ilya Belopolski, Yuanjun Jin +15
By sidestepping the intractable calculations of many-body wavefunctions, density functional theory (DFT) has revolutionized the prediction of ground states of materials. However, p…
Altermagnetism, Kagome Flat Band, and Weyl Fermion States in Magnetically Intercalated Transition Metal Dichalcogenides
Avinash Sah, Ting-Yong Lim, Clayton Conner +5
Altermagnetic (AM) compounds have recently emerged as a promising platform for realizing unconventional quantum phases, enabled by their unique spin-split band structure at zero ne…
Direct Visualization of a Disorder Driven Electronic Smectic Phase in Nonsymmorphic Square-Net Semimetal GdSbTe
Balaji Venkatesan, Syu-You Guan, Jen-Te Chang +14
Electronic liquid crystal (ELC) phases are spontaneous symmetry breaking states believed to arise from strong electron correlation in quantum materials such as cuprates and iron pn…
Strain-Induced Charge Density Waves with Emergent Topological States in Monolayer NbSe2
Wei-Chi Chiu, Sougata Mardanya, Robert Markiewicz +7
Emergence of topological states in strongly correlated systems, particularly two-dimensional (2D) transition-metal dichalcogenides, offers a platform for manipulating electronic pr…
