A note on gradient estimates for the heat semigroup on nonisotropic Heisenberg groups
Ye Zhang
In this note we obtain gradient estimates for the heat semigroup on nonisotropic Heisenberg groups. More precisely, our aim is to get the H.-Q. Li inequality on nonisotropic Heisen…
Comparison of finite-temperature topological indicators based on Uhlmann connection
Ye Zhang, Aixin Pi, Yan He +1
Two indicators of finite-temperature topological properties based on the Uhlmann connection, one generalizing the Wilson loop to the Uhlmann-Wilson loop and the other generalizing…
On the method of differentiation and its application to asymptotics for the heat kernel on H-type groups
Ye Zhang
The aim of this note is twofold. The first one is to find conditions on the asymptotic sequence which ensures differentiation of a general asymptotic expansion with respect to it.…
Insight-HXMT firm detection of the highest energy fundamental cyclotron resonance scattering feature in the spectrum of GRO J1008-57
M. Y. Ge, L. Ji, S. N. Zhang +118
We report on the observation of the accreting pulsar GRO J1008-57 performed by Insight-HXMT at the peak of the source's 2017 outburst. Pulsations are detected with a spin period of…
The evolution of the broadband temporal features observed in the black-hole transient MAXI J1820+070 with Insight-HXMT
Yanan Wang, Long Ji, S. N. Zhang +117
We study the evolution of the temporal properties of MAXI 1820+070 during the 2018 outburst in its hard state from MJD 58190 to 58289 with Insight-HXMT in a broad energy band 1-150…
Joint Analysis of Energy and RMS Spectra from MAXI J1535-571 with Insight-HXMT
L. D. Kong, S. Zhang, Y. P. Chen +115
A new black hole X-ray binary (BHXRB) MAXI J1535-571 was discovered by MAXI during its outburst in 2017. Using observations taken by the first Chinese X-ray satellite, the Hard X-r…
