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…
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…
