Quaternion-Kähler geometry of time reversal symmetric crystals
Hyeongmuk Lim, Junseo Jung, Yuting Qian +1
Quantum geometry reveals how the shape of Bloch wave functions governs correlated quantum phenomena. Its standard formulation describes isolated complex bands, where Berry curvatur…
Quantum Oscillation Signatures of Monopole Charge in Nodal-Ring Semimetals
Aravind Karthigeyan, Yoonseok Hwang, Bohm-Jung Yang +1
Topological semimetals host band nodes characterized by quantized invariants that can appear in bulk responses, yet some invariants remain hidden from standard probes. In particula…
Non-Bloch Quantum Geometry of Non-Hermitian Systems
Junsong Sun, Huaiming Guo, Bohm-Jung Yang
We formulate quantum geometry for non-Hermitian systems under open boundary conditions. By defining quantum-geometric quantities in both real-space and non-Bloch representations, w…
From Berry curvature to quantum metric: a new era of quantum geometry metrology for Bloch electrons in solids
Bohm-Jung Yang
For decades, ``geometry" in band theory has largely meant Berry phase and Berry curvature-quantities that reshape semiclassical dynamics and underpin modern topological matter. Yet…
Geometric Superfluid Weight in Quasicrystals
Junsong Sun, Huaiming Guo, Bohm-Jung Yang
We study the geometric contribution to the superfluidity in quasicrystals in which the conventional momentum-space quantum geometric tensor cannot be defined due to the lack of tra…
Quantum Geometry in Quantum Materials
Jiabin Yu, B. Andrei Bernevig, Raquel Queiroz +3
Quantum geometry, characterized by the quantum geometric tensor, is pivotal in diverse physical phenomena in quantum materials. In condensed matter systems, quantum geometry refers…
Measurements of the quantum geometric tensor in solids
Mingu Kang, Sunje Kim, Yuting Qian +15
Understanding the geometric properties of quantum states and their implications in fundamental physical phenomena is at the core of modern physics. The Quantum Geometric Tensor (QG…
