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.…
Classical symmetry enriched topological orders and distinct monopole charges for dipole-octupole spin ices
Pengwei Zhao, Gang v. Chen
Distinct symmetry enriched topological orders often do not have classical distinctions. Motivated by the recent progress on the pyrochlore spin ice materials based on the dipole-oc…
Z topological orders in kagomé dipolar systems: Feedback from Rydberg quantum simulator
Pengwei Zhao, Gang v. Chen
The mutual feedback between quantum condensed matter and cold atom physics has been quite fruitful throughout history and continues to inspire ongoing research. Motivated by the re…
Multipolar ferroelectricity in the Mott regime
Pengwei Zhao, Jiahao Yang, Gang v. Chen
Ferroelectricity has been one major focus in modern fundamental research and technological application. We consider the physical origin of improper ferroelectricity in Mott insulat…
