Aspects of d-Density Order

TL;DR

This paper reviews and extends the concept of d-density order to arbitrary dimensions, exploring its potential role in describing Mott insulators and inducing quasi-one-dimensional behavior in 2D electron systems.

Contribution

It introduces a generalized framework for d-density order and discusses its implications for Mott insulators and electronic properties in higher dimensions.

Findings

d-density order can support zero modes on domain walls

Dopants may occupy zero modes, affecting electronic behavior

Potential for quasi-one-dimensional behavior in 2D systems

Abstract

I briefly review the concept of d-density ordering, extend it to arbitrary dimensions, and speculate that it might describe Mott insulators. This ordering supports zero modes on domain walls, and quite plausibly dopants occupy such states. This phenomenon could induce quasi-one dimensional behavior in a two-dimensional electron system.
