Modulation of anomalous Hall angle in a magnetic topological semimetal
Jinying Yang, Yanxing Shang, Xingchen Liu +14
The anomalous Hall angle (θA) is a measure of the efficiency of converting a longitudinal driving current to a transverse spin-polarized Hall current. For anomalous Hall sensing, a…
Terahertz third-harmonic generation of lightwave driven Weyl fermions far from equilibrium
Patrick Pilch, Changqing Zhu, Sergey Kovalev +4
We report on time-resolved ultrafast terahertz third-harmonic generation spectroscopy of nonequilibrium dynamics of Weyl fermions in a nanometer thin film of the Weyl semimetal TaP…
Long-range Phase Coherence and Tunable Second Order -Josephson Effect in a Dirac Semimetal
Pranava K. Sivakumar, Mostafa T. Ahari, Jae-Keun Kim +6
Superconducting diode effects have recently attracted much attention for their potential applications in superconducting logic circuits. Several mechanisms such as magneto-chiral e…
Population inversion and ultrafast terahertz nonlinearity of transient Dirac fermions in CdAs
Changqing Zhu, Patrick Pilch, Renato M. A. Dantas +7
Harmonic generation provides an efficient tool for the study of ultrafast nonlinear dynamics. We report on time-resolved optical-pump terahertz-harmonic-generation spectroscopic in…
Self-intercalation as origin of high-temperature ferromagnetism in epitaxially grown Fe5GeTe2 thin films
M. Silinskas, S. Senz, P. Gargiani +8
The role of self-intercalation in 2D van der Waals materials is key to the understanding of many of their properties. Here we show that the magnetic ordering temperature of thin fi…
Exciton-exciton Interaction in Monolayer MoSe from Mutual Screening of Coulomb Binding
Ke Xiao, Tengfei Yan, Chengxin Xiao +7
The potential for low-threshold optical nonlinearity has received significant attention in the fields of photonics and conceptual optical neuron networks. Excitons in two-dimension…
Quantum information diode based on a magnonic crystal
Rohit K. Shukla, Levan Chotorlishvili, Vipin Vijayan +4
Exploiting the effect of nonreciprocal magnons in a system with no inversion symmetry, we propose a concept of a quantum information diode, {\it i.e.}, a device rectifying the amou…
Intrinsic supercurrent non-reciprocity coupled to the crystal structure of a van der Waals Josephson barrier
Jae-Keun Kim, Kun-Rok Jeon, Pranava K. Sivakumar +4
Non-reciprocal electronic transport in a spatially homogeneous system arises from the simultaneous breaking of inversion and time-reversal symmetries. Superconducting and Josephson…
Terahertz spin-to-charge current conversion in stacks of ferromagnets and the transition-metal dichalcogenide NbSe
Lukáš Nádvorník, Oliver Gueckstock, Lukas Braun +16
Transition-metal dichalcogenides (TMDCs) are an aspiring class of materials with unique electronic and optical properties and potential applications in spin-based electronics. Here…
Li iontronics in single-crystalline T-Nb2O5 thin films with vertical ionic transport channels
Hyeon Han, Quentin Jacquet, Zhen Jiang +13
The niobium oxide polymorph T-Nb2O5 has been extensively investigated in its bulk form especially for applications in fast-charging batteries and electrochemical (pseudo)capacitors…
Observation of photoelectric nonvolatile memory and oscillations in VO2 at room temperature
Youngho Jung, Junho Jeong, Zhongnan Qu +4
Vanadium dioxide (VO2) is a phase change material that can reversibly change between high and low resistivity states through electronic and structural phase transitions. Thus far,…
Magnetic Weyl Semimetal Phase in a Kagome Crystal
D. F. Liu, A. J. Liang, E. K. Liu +16
Weyl semimetals are crystalline solids that host emergent relativistic Weyl fermions and have characteristic surface Fermi-arcs in their electronic structure. Weyl semimetals with…
The role of ionic liquid breakdown in the electrochemical metallization of VO2: An NMR study of gating mechanisms and VO2 reduction
Michael A. Hope, Kent J. Griffith, Bin Cui +4
Metallization of initially insulating VO2 via ionic liquid electrolytes (electrolyte gating) has recently been a topic of much interest. It is clear that the metallization takes pl…
