Abstract :
We know Möbius strip in high-school math and Hall effect in general physics. These fundamental sciences, however, are all connected to our recent studies of searching for solid new physics of artificial nanoarchitecture. I will introduce (1) perfect transport occurring in radial superlattice, like carbon nanoscrolls [Ref.1], and (2) higher-order Hall effect existing in nanoarchitectures either with or without applied magnetic field [Refs. 2&3]. This talk will address how to extend our fundamental understandings to explore and predict solid new physics in well-developed nanoarchitectures.
