Terahertz field-induced giant symmetry modulations in a van der Waals antiferromagnet
Sheikh Rubaiat Ul Haque, Martin J. Cross, Sangeeta Rajpurohit +19
Strong-field terahertz (THz) excitations enable dynamic control over electronic, lattice and symmetry degrees of freedom in quantum materials. Here, we uncover pronounced terahertz…
Honeycomb oxide heterostructure: a new platform for Kitaev quantum spin liquid
Baekjune Kang, Miju Park, Sehwan Song +11
Kitaev quantum spin liquid, massively quantum entangled states, is so scarce in nature that searching for new candidate systems remains a great challenge. Honeycomb heterostructure…
Ultrafast dynamics in the Lifshitz-type 5 pyrochlore antiferromagnet CdOsO
Inho Kwak, Min-Cheol Lee, Byung Cheol Park +7
We investigate the ultrafast dynamics of CdOsO, a prototype material showing a Lifshitz-type transition as a function of temperature. In the paramagnetic metallic state…
Strong spin-phonon coupling unveiled by coherent phonon oscillations in Ca2RuO4
Min-Cheol Lee, Choong H. Kim, Inho Kwak +8
We utilize near-infrared femtosecond pulses to investigate coherent phonon oscillations of Ca2RuO4. The coherent Ag phonon mode of the lowest frequency changes abruptly not only it…
