Probing Cosmic Strings with Gravitational-Wave Fringe
Sunghoon Jung, TaeHun Kim
Cosmic strings are important remnants of early-Universe phase transitions. We show that they can be probed by Gravitational Waves (GWs) from compact binary mergers. If such chirpin…
Hybridization and Decay of Magnetic Excitations in two-dimensional Triangular Lattice Antiferromagnets
Taehun Kim, Kisoo Park, Jonathan C. Leiner +1
Elementary quasiparticles in solids such as phonons and magnons occasionally have nontrivial interactions between them, as well as among themselves. As a result, their energy eigen…
Renormalization of spin excitations in hexagonal HoMnO3 by magnon-phonon coupling
Taehun Kim, Jonathan C. Leiner, Kisoo Park +5
Hexagonal HoMnO3, a two-dimensional Heisenberg antiferromagnet, has been studied via inelastic neutron scattering. A simple Heisenberg model with a single-ion anisotropy describes…
Magnetic excitations in bulk multiferroic two-dimensional triangular lattice antiferromagnet (Lu,Sc)FeO
J. C. Leiner, Taehun Kim, Kisoo Park +7
Non-collinear two-dimensional triangular lattice antiferromagnets (2D TLAF) are currently an area of very active research due to their unique magnetic properties, which lead to non…
Giant thermal hysteresis in Verwey transition of single domain Fe3O4 nanoparticles
Taehun Kim, Sumin Lim, Jaeyoung Hong +12
Most interesting phenomena of condensed matter physics originate from interactions among different degrees of freedom, making it a very intriguing yet challenging question how cert…
