Tunable Superconductivity Mediated by Heavy-Electron Plasmons: Band-Structure and Quantum-Geometric Engineering
Sang Hyun Park, Junyeong Ahn
Conventional superconductivity derives its pairing glue from lattice vibrations, tying its characteristic scales to chemistry and atomic masses. Plasmonsthe collective oscillati…
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…
Topological Enhancement of Nonlinear Transports in Unconventional Point-Node Semimetals
Junyeong Ahn
The topological singularity of the Bloch states close to the Fermi level significantly enhances nonlinear electric responses in topological semimetals. Here, we systematically char…
Axion optical induction of antiferromagnetic order
Jian-Xiang Qiu, Christian Tzschaschel, Junyeong Ahn +25
Using circularly-polarized light to control quantum matter is a highly intriguing topic in physics, chemistry and biology. Previous studies have demonstrated helicity-dependent opt…
Topological Circular Dichroism in Chiral Multifold Semimetals
Junyeong Ahn, Barun Ghosh
Uncovering the physical contents of the nontrivial topology of quantum states is a critical problem in condensed matter physics. Here, we study the topological circular dichroism i…
Rare-earth monopnoctides -- family of antiferromagnets hosting magnetic Fermi arcs
Yevhen Kushnirenko, Benjamin Schrunk, Brinda Kuthanazhi +8
Since the discovery of topological insulators a lot of research effort has been devoted to magnetic topological materials, in which non-trivial spin properties can be controlled by…
