Spin wavepackets in the Kagome ferromagnet FeSn: propagation and precursors
Changmin Lee, Yue Sun, Linda Ye +6
The propagation of spin waves in magnetically ordered systems has emerged as a potential means to shuttle quantum information over large distances. Conventionally, the arrival time…
Spin-carrier coupling induced ferromagnetism and giant resistivity peak in EuCdP
Veronika Sunko, Yue Sun, Mayia Vranas +14
EuCdP is notable for its unconventional transport: upon cooling the metallic resistivity changes slope and begins to increase, ultimately 100-fold, before returning to its…
Band Structure Driven Thermoelectric Response of Topological Semiconductor ZrTe
Junbo Zhu, Changmin Lee, Fahad Mahmood +4
We report a transport, thermodynamic, and spectroscopic study of the recently identified topological semiconductor ZrTe with a focus on elucidating the connections between its…
Quantum Imaging of Single-Atom Spin-Splitting in a Monolayer Semiconductor
Caleb Z. Zerger, Alex W. Contryman, Changmin Lee +8
Theoretical work has suggested that monolayer MoS2 doped with Mn should behave as a two-dimensional dilute magnetic semiconductor, which would open up possibilities for spintronic…
Mapping Domain Wall Topology in the Magnetic Weyl Semimetal CeAlSi
Yue Sun, Changmin Lee, Hung-Yu Yang +3
We report full vector mapping of local magnetization in CeAlSi, a Weyl semimetal in which both inversion and time-reversal symmetries are broken. The vector maps reveal unanticipat…
Observation of a phase transition within the domain walls of ferromagnetic Co3Sn2S2
Changmin Lee, Praveen Vir, Kaustuv Manna +5
The ferromagnetic phase of CoSnS is widely considered to be a topological Weyl semimetal, with evidence for momentum-space monopoles of Berry curvature from transport a…
The spontaneous symmetry breaking in TaNiSe is structural in nature
Edoardo Baldini, Alfred Zong, Dongsung Choi +16
The excitonic insulator is an electronically-driven phase of matter that emerges upon the spontaneous formation and Bose condensation of excitons. Detecting this exotic order in ca…
High resolution time- and angle-resolved photoemission spectroscopy with 11 eV laser pulses
Changmin Lee, Timm Rohwer, Edbert J. Sie +8
Performing time and angle resolved photoemission spectroscopy (tr-ARPES) at high momenta necessitates extreme ultraviolet laser pulses, which are typically produced via high harmon…
Observation of three-state nematicity in the triangular lattice antiferromagnet Fe NbS
Arielle Little, Changmin Lee, Caolan John +9
Nematic order is the breaking of rotational symmetry in the presence of translational invariance. While originally defined in the context of liquid crystals, the concept of nematic…
Disentangling amplitude and phase dynamics of a charge density wave in a photo-induced phase transition
Alfred Zong, Anshul Kogar, Ya-Qing Bie +16
Upon excitation with an intense ultrafast laser pulse, a symmetry-broken ground state can undergo a non-equilibrium phase transition through pathways dissimilar from those in therm…
Direct measurement of proximity-induced magnetism at the interface between a topological insulator and a ferromagnet
Changmin Lee, Ferhat Katmis, Pablo Jarillo-Herrero +2
When a topological insulator (TI) is in contact with a ferromagnet, both time reversal and inversion symmetries are broken at the interface. An energy gap is formed at the TI surfa…
Small-sized Dichroic Atomic Vapor Laser Lock (DAVLL)
Changmin Lee, G. Z. Iwata, E. Corsini +4
Two, lightweight diode laser frequency stabilization systems designed for experiments in the field are described. A significant reduction in size and weight in both models supports…
