Supermoiré domain-resolved effective Hamiltonians and valley topology in helical multilayer graphene
Kyungjin Shin, Nicolas Leconte, Jeil Jung +1
Extending moiré graphene beyond twisted bilayers, helical trilayer graphene has shown topological bands and correlated states with reshaped moiré periodicity. Here we develop a the…
Unveiling three types of fermions in a nodal ring topological semimetal through magneto-optical transitions
Jiwon Jeon, Taehyeok Kim, Jiho Jang +5
We investigate the quasiparticles of a single nodal ring semimetal SrAs through axis-resolved magneto-optical measurements. We observe three types of Landau levels scaling as $…
Sliding-dependent electronic structures of alternating-twist tetralayer graphene
Kyungjin Shin, Jiseon Shin, Yoonsung Lee +2
We study the electronic structure of alternating-twist tetralayer graphene, especially near its magic angle , for different AA, AB, and SP sliding geometries at thei…
Effect of trivial bands on chiral anomaly-induced longitudinal magnetoconductivity in Weyl semimetals
Jeonghyeon Suh, Hongki Min
Including the effect of the trivial band near Weyl nodes, we evaluate the longitudinal magnetoconductivity (LMC) of Weyl semimetals along the magnetic field direction using the Bol…
Sub-MeV Dark Matter Detection with Bilayer Graphene
Anirban Das, Jiho Jang, Hongki Min
The light dark matter mass regime has emerged as the next frontier in the direct detection experiment due to the lack of any detection signal in the higher mass range. In this pape…
