Monolayer van der Waals kagome lattice for high-temperature flat-band physics
Hyungkun Bong, Choongjae Won, Seongyong Lee +26
Kagome lattice materials host a remarkably rich landscape of novel quantum phenomena, all arising from the intrinsic interplay of topology, correlation, and frustration. While prev…
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…
Development of a Capacitance Measurement for Pulsed Magnetic Fields
William K. Peria, Shengzhi Zhang, Sangyun Lee +4
Capacitance measurements are crucial for probing the electrical properties of materials. In this study, we develop and implement a capacitance measurement technique optimized for p…
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…
Spin Excitation Continuum in the Exactly Solvable Triangular-Lattice Spin Liquid CeMgAl11O19
Bin Gao, Tong Chen, Chunxiao Liu +17
In magnetically ordered insulators, elementary quasiparticles manifest as spin waves - collective motions of localized magnetic moments propagating through the lattice - observed v…
Frustrated phonon with charge density wave in vanadium Kagome metal
Seung-Phil Heo, Choongjae Won, Heemin Lee +12
The formation of a star of David CDW superstructure, resulting from the coordinated displacements of vanadium ions on a corner sharing triangular lattice, has garnered significant…
Kinkless electronic junction along one dimensional electronic channel
Qirong Yao, Jae Whan Park, Choongjae Won +2
Here we report the formation of type-A and type-B electronic junctions without any structural discontinuity along a well-defined 1-nm-wide one-dimensional electronic channel within…
