Fractional Quantum Geometry in Topological Mott Regime
Junyu Tang, Hongquan Lv, Gang v. Chen
Inspired by recent interests in quantum geometry in electronic bands, we consider a two-dimensional topological Mott insulator, i.e. chiral spin liquid, whose spinon bands develop…
Kane-Lubensky phonons in Maxwell lattice frustrated Mott insulators
Hong-Hao Song, Gang v. Chen
We show that zero-energy gapless Weyl-line phonons of the Kane-Lubensky's type can arise in the three-dimensional Maxwell lattice frustrated Mott insulators through the magnetopolo…
Non-Abelian Anyon Braiding with Quantum-Antidot Interferometry
Junyu Tang, Gang v. Chen
Conventional Fabry--Perot interferometry accesses only full braids of anyons and therefore cannot directly probe the elementary \(π\)-rotation exchange. Motivated by the recent qua…
3D Ising criticality with Platonic lattice superconducting qubits
Liyang Sui, Hong-Hao Song, Sainan Huai +13
The three-dimensional (3D) Ising model is a foundational model in statistical physics and critical phenomena, yet its analytical intractability has long impeded the precise determi…
Quantum oscillations in proximity to high-angular-momentum band inversion
Jiahao Yang, Gang v. Chen
Quantum oscillations provide a fundamental probe of electronic structure in magnetic fields, revealing the Fermi surface topology in metals, and/or the quasiparticle properties eve…
Phononic enhancement and detection of hidden spin-nematicity and dynamics in quantum magnets
Junyu Tang, Hong-hao Song, Gang v. Chen
The spin nematic phase, characterized by long-range order of spin quadrupole moments in the absence of dipolar magnetism, presents a significant challenge for conventional experime…
Magnetopological mechanics in Maxwell lattice frustrated Mott insulators
Hong-Hao Song, Pengwei Zhao, Gang v. Chen
Topological boundary modes, a hallmark of quantum topological phases, remarkably occur in classical mechanical systems through an interesting correspondence with the quantum case.…
