Plasmons in semiconductor and topological insulator wires with large dielectric constant

Yi Huang, Chao-Hsiang Sheu, B. I. Shklovskii

The dispersion law of plasmons running along thin wires with radius $a$ is known to be practically linear. We show that in a wire with a dielectric constant $κ$ much larger than th…

Treating Divergent Perturbation Theory: Lessons from Exactly Solvable 2D Models at Large $N$

Daniel Schubring, Chao-Hsiang Sheu, Mikhail Shifman

We consider the operator product expansion (OPE) of correlation functions in the supersymmetric $O (N)$ non-linear sigma model at sub-leading order in the large $N$ limit in order t…

Long Way to Ricci Flatness

Jin Chen, Chao-Hsiang Sheu, Mikhail Shifman +2

We study two-dimensional weighted $N = 2$ supersymmetric $CP$ models with the goal of exploring their infrared (IR) limit. $WCP (N, N)$ are sim…

From Gauged Linear Sigma Models to Geometric Representation of $WCP (N, N ~)$ in 2D

Chao-Hsiang Sheu, Mikhail Shifman

In this paper two issues are addressed. First, we discuss renormalization properties of a class of gauged linear sigma models (GLSM) which reduce to $WCP (N, N ~)$ non…
