The bulk spectral gap is semi-decidable: a convergent family of certified upper bounds
Xiangling Xu, Matthias Schötz, Jie Wang +4
Determining spectral gaps in the thermodynamic limit is a central challenge in quantum many-body physics. Existing rigorous methods are largely limited to special settings, while v…
Off-shell Hessian thermodynamic stability of higher-curvature black holes
Chen-Hao Hao, Jieci Wang
We develop a branch-sensitive thermodynamic framework for higher-curvature black holes using the off-shell Gibbs free energy and the Wald entropy as the basic da…
The Calabi flow with prescribed curvature on finite graphs
Yi Li, Jie Wang, Pingsan Yuan +1
In this paper, we investigate the prescribed curvature problem associated with a special Lin-Lu-Yau curvature on finite graphs of girth at least 6. We define the corresponding Cala…
Proca-Maxwell System in an Infinite Tower of Higher-Derivative Gravity
Chen-Hao Hao, Yong-Qiang Wang, Jieci Wang
We numerically construct a five-dimensional Proca-Maxwell system coupled to an infinite tower of higher-derivative gravity, parameterized by the correction order and coupling const…
Gaussian tripartite steering in Schwarzschild black hole
Shu-Min Wu, Hao-Yu Wu, Yu-Xuan Wang +1
Multipartite steering is a fundamental quantum resource that is uniquely suited to tackling complex relativistic quantum information challenges, but its properties in the gravitati…
