X-ray magnetic circular dichroism evidence of intrinsic -wave altermagnetism in rutile-structure NiF
Zezhong Li, Kosuke Sakurai, Yiu-Fung Chiu +13
We present the x-ray magnetic circular dichroism (XMCD) at the Ni -edge as an evidence of the -wave altermagnetism in rutile-structure NiF. Sizable XMCD signal is o…
Yu-Shiba-Rusinov bound states of exciton condensate
SeongJin Kwon, Kyung-Hwan Jin, Jong Eun Han +4
Quantum condensed states in solids often reveal their fundamental nature via interactions with impurities, as epitomized by Yu-Shiba-Rusinov (YSR) bound states at magnetic impuriti…
Altermagnetic boosting of chiral phonons
J. Okamoto, C. Y. Mou, H. Y. Huang +10
Chirality characterizes the asymmetry between a structure and its mirror image and underlies a wide range of chiral functionalities. In crystallographically chiral materials, phono…
Exciton photoemission from a ground state of a solid Ta2Pd3Te5
Siwon Lee, Kyung-Hwan Jin, SeongJin Kwon +6
Excitons are bosonic quasiparticles with a variety of applications in optoelectronics, photosyn thesis, and dissipationless informatics, and their lifetime can become sufficiently…
Time-domain decoding of unconventional charge order mechanisms in nonmagnetic and magnetic kagome metals
Seongyong Lee, Byungjune Lee, Hoyoung Jang +11
In kagome lattice materials, quantum interplay between charge, spin, orbital, and lattice degrees of freedom gives rise to a remarkably rich set of emergent phenomena, ranging from…
Chiral Pseudogap Metal Emerging from a Disordered van der Waals Mott Insulator 1T-TaS2-xSex
Hyunjin Jung, Jiwon Jung, ChoongJae Won +5
The emergence of a pseudogap is a hallmark of anomalous electronic states formed through substantial manybody interaction but the mechanism of the pseudogap formation and its role…
