Gate-tunable quantum pathways of high harmonic generation in graphene
Soonyoung Cha, Minjeong Kim, Youngjae Kim +14
Under strong laser fields, electrons in solids radiate high-harmonic fields by travelling through quantum pathways in Bloch bands in the sub-laser-cycle timescales. Understanding t…
Single crystal growth of iridates without platinum impurities
Jimin Kim, Hoon Kim, Hyun-Woo J. Kim +7
Iridates have attracted much interest in the last decade for their novel magnetism emerging in the limit of strong spin-orbit coupling and possible unconventional superconductivity…
SrIrO/SrIrO superlattice for a model 2D quantum Heisenberg antiferromagnet
Hoon Kim, Joel Bertinshaw, J. Porras +9
Spin-orbit entangled pseudospins hold promise for a wide array of exotic magnetism ranging from a Heisenberg antiferromagnet to a Kitaev spin liquid depending on the lattice and bo…
Local characterization of a heavy-fermion superconductor via sub-Kelvin magnetic force microscopy
Dirk Wulferding, Geunyong Kim, Hoon Kim +5
Using magnetic force microscopy operating at sub-Kelvin temperatures we characterize the heavy-fermion superconductor CeCoIn. We pinpoint the absolute London penetration depth…
Superconductivity emerging from a stripe charge order in IrTe2 nanoflakes
Sungyu Park, So Young Kim, Hyoung Kug Kim +15
Superconductivity in the vicinity of a competing electronic order often manifests itself with a superconducting dome, centred at a presumed quantum critical point in the phase diag…
Direct observation of excitonic instability in Ta2NiSe5
Kwangrae Kim, Hoon Kim, Jonghwan Kim +3
Coulomb attraction between electrons and holes in a narrow-gap semiconductor or a semimetal is predicted to lead to an elusive phase of matter dubbed 'excitonic insulator'. However…
Direct observation of the M2 phase with its Mott transition in a VO film
Hoon Kim, Tetiana V. Slusar, Dirk Wulferding +7
In VO, the explicit origin of the insulator-to-metal transition is still disputable between Peierls and Mott insulators. Along with the controversy, its second monoclinic (M2)…
