Robust Interlayer-Coherent Quantum Hall States in Twisted Bilayer Graphene
Dohun Kim, Byungmin Kang, Yong-Bin Choi +5
We introduce a novel two-dimensional electronic system with ultrastrong interlayer interactions, namely twisted bilayer graphene with a large twist angle, as an ideal ground for re…
Gate-tunable quantum pathways of high harmonic generation in graphene
Soonyoung Cha, Minjeong Kim, Youngjae Kim +14
Under strong laser fields, electrons in solids radiate high-harmonic fields by travelling through quantum pathways in Bloch bands in the sub-laser-cycle timescales. Understanding t…
Classification of Fermionic Topological Orders from Congruence Representations
Gil Young Cho, Hee-cheol Kim, Donghae Seo +1
The fusion rules and braiding statistics of anyons in D fermionic topological orders are characterized by the modular data of a super-modular category. On the other hand, th…
A symmetry principle for gauge theories with fractons
Yuji Hirono, Minyoung You, Stephen Angus +1
Fractonic phases are new phases of matter that host excitations with restricted mobility. We show that a certain class of gapless fractonic phases are realized as a result of spont…
Controllable Floquet edge modes in a multi-frequency driving system
HaRu K. Park, Junmo Jeon, Gil Young Cho +1
A driven quantum system has been recently studied in the context of nonequilibrium phase transitions and their responses. In particular, for a periodically driven system, its dynam…
Chiral anomaly in noncentrosymmetric systems induced by spin-orbit coupling
Suik Cheon, Gil Young Cho, Ki-Seok Kim +1
The chiral anomaly may be realized in condensed matter systems with pairs of Weyl points. Here we show that the chiral anomaly can be realized in diverse noncentrosymmetric systems…
