A Hard-Core Subshift Whose Sofic Mean Dimension Depends on the Sofic Approximation

Xianqiang Li, Zhuowei Liu

We exhibit a topologically mixing continuous-alphabet subshift of the free group whose sofic mean dimension depends on the chosen homomorphic sofic approximation, which gives…

Equivalence of Sofic -Metric Mean Dimensions and a Tame-Metric Variational Formula

Xianqiang Li, Zhuowei Liu

Let be a countable discrete sofic group acting by homeomorphisms on a compact metrizable space and a sofic approximation of . We prove that for every $1\leq p<\in…

Relative entropy, topological pressure and variational principle for locally compact sofic group actions

Xianqiang Li, Zhuowei Liu

For a locally compact sofic group continuously acting on a compact metric space, we first study the relative sofic entropy and prove an additive inequality relating sofic entropy a…

Distinct topological excitonic insulators characterized by quantum geometry

Zhuowei Liu, Rui Wang, Baigeng Wang

Theintertwining of electron-hole correlation and nontrivial topology is known to give rise to exotic topological excitonic insulators. Here, we show that the involvement of quantum…

Sofic conditional mean dimension, relative sofic mean dimension and their localizations

Xianqiang Li, Zhuowei Liu, Xiaofang Luo

Let be a factor map between continuous actions of a sofic group , we study sofic conditional mean dimension and relative sofic mean dimension introduced in…
