Chern-Simons-Ginzburg-Landau Theory of Fractional Quantum Hall Hierarchies
Taegon Lee, Gil Young Cho, Donghae Seo
We construct effective Chern-Simons-Ginzburg-Landau theories for Abelian and non-Abelian fractional quantum Hall hierarchies for those which had previously been des…
A Unified Categorical Description of Quantum Hall Hierarchy and Anyon Superconductivity
Donghae Seo, Taegon Lee, Gil Young Cho
We present a unified category-theoretic framework for quantum Hall hierarchy constructions and anyon superconductivity based on modular tensor categories over $\mathrm{Rep}(\mathrm…
Holevo bound and objectivity in the boson-spin model
Tae-Hun Lee, JarosÅaw K. Korbicz
Emergence of objective, classical properties in quantum systems can be described in the modern language of quantum information theory. In this work, we present an example of such a…
Encoding position by spins: Objectivity in the boson-spin model
Tae-Hun Lee, JarosÅaw K. Korbicz
We investigate quantum objectivity in the boson-spin model, where a central harmonic oscillator interacts with a thermal bath of spin-1/2 systems. We analyze how information about…
