Bounded orbits on homogeneous spaces and bounded geodesics on locally symmetric spaces
Chengyang Wu
We present a unified approach to proving the following two results: (i) Let be a Lie group, a lattice in , , and let be a one-parameter -diagonal…
is Hyperplane Absolute Winning
Chengyang Wu
Given an -dimensional weight and an -dimensional weight , we prove that the set of -badly approximable matrices…
Winning property of counterexamples to Uniform Littlewood's Conjecture
Vasiliy Neckrasov, Chengyang Wu, Bohan Yang
In this paper, we prove that the set of counterexamples to the uniform Littlewood's conjecture proposed in Bandi-Fregoli-Kleinbock, that is, the set of pairs of real numbers $(x,y)…
Singular points for cone actions on the product of certain homogeneous spaces
Lifan Guan, Chengyang Wu
In this paper, we investigate divergent orbits for cone actions on products of certain homogeneous spaces. We introduce a notion of essential singularity for such actions, and esti…
Universal scaling of many-body effects in quantum tunneling
Hongmian Shui, Chi-Kin Lai, Chengyang Wu +6
Quantum tunneling is fundamental to diverse phenomena and underpins a wide range of modern technologies. In the study of superconducting quantum computation and high-temperature su…
The wave nature of a Mott insulator
Xudong Yu, Chengyang Wu, Wenhan Chen +10
Quantum phases of matter are routinely identified by coherence features, with interference patterns being one of the most directly observable quantities. In lattices, the superflui…
