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…
Thickness-driven crossover from conventional to chiral nonreciprocal superconductivity in kagome metal CsV3Sb5
Wei Zhang, Jiangbo Luo, Nikolai Peshcherenko +10
Superconductivity and its potential applications are governed by the symmetry of the superconducting order parameter. In the kagome metal CsV3Sb5, most bulk studies indicate conven…
Observation of the Magnus Nonlinear Hall effect from Chiral Weyl Monopoles
Heda Zhang, Nikolai Peshcherenko, Ning Mao +4
The nonlinear Hall effect (NLHE) connects crystalline symmetry to quantum geometry, offering a probe of band topology beyond linear transport. While most studies have focused on th…
Programmable, Spontaneous Superlattice Memory in a Monolayer Topological Insulator
Jian Tang, Thomas Siyuan Ding, Shuhan Ding +24
Memory is a foundational concept across disciplines, from neurobiology and electronics to artificial intelligence and quantum gravity. In materials, memory effects typically arise…
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…
Efficient spin-pumping and spin transport across epitaxial MnSn(0001) noncollinear antiferromagnet/permalloy interfaces

The generation and control of spin currents are crucial for advancing next-generation spintronic technologies. These technologies depend on materials capable of efficiently sourcin…
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…
Chiral superconductivity from spin polarized Chern band in twisted MoTe
Cheng Xu, Nianlong Zou, Nikolai Peshcherenko +4
Superconductivity has been observed in twisted MoTe2 within the anomalous Hall metal parent state. Key signatures-including a fully spin/valley polarized normal state, anomalous Ha…
Interplay between topology and correlations in the second moiré band of twisted bilayer MoTe2
Fan Xu, Xumin Chang, Jiayong Xiao +17
Topological flat bands formed in two-dimensional lattice systems offer unique opportunity to study the fractional phases of matter in the absence of an external magnetic field. Cel…
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…
Wannier functions, minimal model and charge transfer in PbCuPO
Ning Mao, Nikolai Peshcherenko, Yang Zhang
Recent preprints claimed that the copper doped lead apatite PbCuPO (LK99) might be a high-temperature superconductor because of its strong diamagnetism and transport…
