Learning complexity of many-body quantum sign structures through the lens of Boolean Fourier analysis
We study sign structures of the ground states of spin-1/2 magnetic systems using the methods of Boolean Fourier analysis. Previously it …

Chiral tunneling through generic one-dimensional potential barriers in bilayer graphene
We study tunneling of charge carriers in single- and bilayer graphene. We propose an explanation for nonzero “magic angles” with 100% …

On the adjacency quantization in an equation modeling the Josephson effect
We study a two-parameter family of nonautonomous ordinary differential equations on the 2-torus. This family models the Josephson …
