Revealing Intrinsic Anisotropy of Collective Magnetic Excitations in Twinned Crystals of a Kitaev-Heisenberg Quantum Magnet
Naipeng Zhang, Nikolai Simonov, Mykhaylo Ozerov +11
Quantum magnets with competing interactions often emerge from delicate balances among microscopic parameters, making it essential to disentangle intrinsic spin dynamics from extrin…
Sharp spectroscopic fingerprints of disorder in an incompressible magnetic state
Chaebin Kim, Sumedh Rathi, Naipeng Zhang +15
Disorder significantly impacts the electronic properties of conducting quantum materials by inducing electron localization and thus altering the local density of states and electri…
Isotropic Dirac fermion and anomalous oscillator strength of zeroth Landau level transition
Zeping Shi, Wenbin Wu, Guangyi Wang +12
Dirac fermions, characterized by their linear dispersion and relativistic nature, have emerged as a prominent class of quasiparticles in condensed matter physics. While the Dirac e…
Field-induced magnetic phase transition driven by a ground state level-crossing in CsErSe
Hope Whitelock, Allen O. Scheie, Marissa McMaster +12
We report a comprehensive study of the low-temperature magnetic properties of the insulating rare-earth triangular magnet CsErSe. We uncover a field-induced level crossing at t…
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…
Lithography defined semiconductor moires with anomalous in-gap quantum Hall states
Wei Pan, D. Bruce Burckel, Catalin D. Spataru +16
Quantum materials and phenomena have attracted great interest for their potential applications in next-generation microelectronics and quantum-information technologies. In one espe…
