Bloch Oscillations and Landau-Zener Transitions in Flat-Band Lattices with Quadratic and Linear Band Touchings
Chenhaoyue Wang, Carlos J. Garcia-Cervera, Amartya S. Banerjee
Bloch oscillations (BOs) describe the coherent oscillatory motion of electrons in a periodic lattice under a constant external electric field. Deviations from pure harmonic wave pa…

Multiscale analysis of large twist ferroelectricity and swirling dislocations in bilayer hexagonal boron nitride
Md Tusher Ahmed, Chenhaoyue Wang, Amartya S. Banerjee +1
With its atomically thin structure and intrinsic ferroelectric properties, heterodeformed bilayer hexagonal boron nitride (hBN) has gained prominence in next-generation non-volatil…

Dirac Fermions and Flat Bands in Phosphorus Carbide Nanotubes: Structural and Quantum Phase Transitions in a Quasi-One-Dimensional Material
Shivam Sharma, Chenhaoyue Wang, Hsuan Ming Yu +1
Chemically realistic quasi-one-dimensional (1D) materials in which Dirac fermions and highly degenerate flat bands coexist intrinsically at the Fermi level are exceedingly rare, wh…
