Research on the knee region of cosmic ray by using a novel type of electron–neutron detector array
By accurately measuring composition and energy spectrum of cosmic ray, the origin problem of so called “knee” region (energy >one PeV) can be solved. However, up to the present, the results of the spectrum in ...

Open AccessPage curves for accelerating black holes
The island paradigm for the fine-grained entropy of Hawking radiation is applied to eternal charged accelerating black holes. In the absence of the island, the entanglement entropy grows linearly and divergent...

Itinerant to relocalized transition of f electrons in the Kondo insulator CeRu4Sn6
The three-dimensional electronic structure and the nature of Ce 4f electrons of the Kondo insulator CeRu4Sn6 are investigated by angle-resolved photoemission spectroscopy, utilizing tunable photon energies. Our r...

Open AccessPage curve and phase transition in deformed Jackiw–Teitelboim gravity
We consider the entanglement island in a deformed Jackiw–Teitelboim black hole in the presence of the phase transition. This black hole has the van der Waals–Maxwell-like phase structure as it is coupled with ...

Open AccessCosmological time crystals from Einstein-cubic gravities
By including appropriate Riemann-cubic invariants, we find that the dynamics of classical time crystals can be straightforwardly realized in Einstein gravity on the FLRW metric. The time reflection symmetry is...

Open AccessOn the size of rotating black holes
Recently a sequence of inequalities relating the black hole horizon, photon sphere, shadow were proposed for spherically symmetric and static black holes, providing the upper bound for given mass. In this pape...

Open AccessCanonical interpretation of Y(10750) and \(\Upsilon (10860)\) in the \(\Upsilon \) family
Inspired by the new resonance Y(10750), we calculate the masses and two-body OZI-allowed strong decays of the higher vector bottomonium sates within both screened and linear potential models. We discuss the possi...

Open AccessHorndeski gravity and the violation of reverse isoperimetric inequality
We consider Einstein–Horndeski–Maxwell gravity, together with a cosmological constant and multiple Horndeski axions. We construct charged AdS planar black holes in general dimensions where the Horndeski axions...

Open AccessHigher-derivative gravity with non-minimally coupled Maxwell field
We construct higher-derivative gravities with a non-minimally coupled Maxwell field. The Lagrangian consists of polynomial invariants built from the Riemann tensor and the Maxwell field strength in such a way ...

Introduction to the CDEX experiment
It is believed that weakly interacting massive particles (WIMPs) are candidates for dark matter (DM) in our universe which come from outer space and might interact with the standard model (SM) matter of our de...
