Chern Character for Discrete Spectrum Partition Function
Shunrui Li, Yang Liu
We establish a rigorous geometric correspondence between thermal partition functions of discrete-spectrum quantum systems with bounded ground energy and the Chern character of "vir…
Non-SUSY physics and the Atiyah-Singer index theorem
Shunrui Li, Yang Liu
The Atiyah-Singer index theorem, a cornerstone of modern mathematics, has traditionally been derived from supersymmetric (SUSY) physics. This paper demonstrates a direct derivation…
Global Type IIA Vacuum: A Unified Model for the Standard Model and Cosmology
Yang Liu
We propose a unified framework within Type IIA string theory, based on a globally consistent intersecting D6-brane model compactified on a …
Quantum harmonic oscillator, index theorem and spectral asymmetry
Shunrui Li, Yang Liu
We report a spectral asymmetry effect in the quantum harmonic oscillator, where its partition function is identified as the Chern character. This establishes a direct link between…
Resolving Geometric Excitations of Fractional Quantum Hall States
Yang Liu, Tongzhou Zhao, T. Xiang
The quantum dynamics of the intrinsic metric profoundly influence the neutral excitations in the fractional quantum Hall system, as established by Haldane in 2011 \cite{Haldane2011…
Vacuum transitions with the Gauss-Bonnet term in dimensions
Yang Liu
In our previous paper [1,2], we proposed a probabilistic argument to explain the reason why the cosmological constant is very small in . We can ask a question: if the behavior…
Holography for Sp(2) Gauge Dynamics: from Composite Higgs to Technicolour
Johanna Erdmenger, Nick Evans, Yang Liu +1
We study Sp(2) gauge dynamics with two Dirac fermion flavours in the fundamental representation. These strongly coupled systems underlie some composite Higgs models with a glo…
Kerr-like metric in 4D Double Field Theory
Shunrui Li, Yang Liu
Double Field Theory suggests that people can view the whole massless NS-NS sector as the gravitational unity. The covariance and the doubled diffeomorphisms determine prec…
Observational Tests of 4D Double Field Theory
Shunrui Li, Yang Liu
Although General Relativity (GR) is a very successful theory of gravity, it cannot explain every observational phenomenon. People have tried many kinds of modified gravity theory t…
