Carrier duality from the convergence of Dirac fermions and high-order van Hove singularities
Meng Lyu, Kaiyi Zhai, Nikolai Peshcherenko +15
The convergence of highly mobile Dirac fermions and flat-band heavy electrons offers a paradigm for emergent quantum phenomena. However, experimental realization of such intriguing…
Interpretation of Crystal Energy Landscapes with Kolmogorov-Arnold Networks
Gen Zu, Ning Mao, Claudia Felser +1
Characterizing crystalline energy landscapes is essential to predicting thermodynamic stability, electronic structure, and functional behavior. While machine learning (ML) enables…
Chiralometer: Direct Torque Detection of Crystal Chirality
Nikolai Peshcherenko, Ning Mao, Claudia Felser +1
Chirality governs phenomena ranging from chemical reactions to the topology of quasiparticle charge carriers. However, a direct macroscopic probe for crystal chirality remains a si…
Universal giant spin Hall effect in moire metal
Ning Mao, Cheng Xu, Ting Bao +3
While moiré phenomena have been extensively studied in low-carrier-density systems such as graphene and semiconductors, their implications for metallic systems with large Fermi sur…
Observation of Phonon Angular Momentum
Heda Zhang, N. Peshcherenko, F. Yang +7
Angular momentum (AM), a fundamental concept describing the rotation of an object about an axis, profoundly influences all branches of physics. In condensed matter, AM is intimatel…
Sublinear transport in Kagome metals: Interplay of Dirac cones and Van Hove singularities
Nikolai Peshcherenko, Ning Mao, Claudia Felser +1
Kagome metals are known to host Dirac fermions and saddle point Van Hove singularities near Fermi level. With the minimal two-pocket model (Dirac cone + Van Hove singularity), we p…
Quantized nonlinear Hall effect from chiral monopole
Nikolai Peshcherenko, Claudia Felser, Yang Zhang
Nonlinear Hall effect arises in materials without inversion symmetry, and the intrinsic contribution is typically from Berry curvature dipole of non-universal Fermi pockets. Here w…
