Observable effect of quantized cylindrical gravitational waves
Feifan He, Baocheng Zhang
We investigate the response of a model gravitational wave detector consisting of two particles to the quantized cylindrical gravitational waves and obtain a relation between the st…
A protocol of potential advantage in the low frequency range to gravitational wave detection with space based optical atomic clocks
Feifan He, Baocheng Zhang
A recent proposal describes space based gravitational wave (GW) detection with optical lattice atomic clocks [Kolkowitz et. al., Phys. Rev. D 94, 124043 (2016)] [1]. Based on their…
A divergent volume for black holes calls for no "firewall"
Baocheng Zhang, Li You
The presumption that Hawking radiations are thermally distributed can be considered to result from their entanglement with the internal degrees of freedom for a black hole. This le…
Would quantum entanglement be increased by anti-Unruh effect?
Taotao Li, Baocheng Zhang, Li You
We study the "anti-Unruh effect" for an entangled quantum state in reference to the counterintuitive cooling previously pointed out for an accelerated detector coupled to the vacuu…
On the entropy associated with the interior of a black hole
Baocheng Zhang
The investigation about the volume of a black hole is closely related to the quantum nature of the black hole. The entropy is a significant concept for this. A recent work by Majhi…
Smarr formula for BTZ black holes in general three-dimensional gravity models
Chao Liang, Li Gong, Baocheng Zhang
Recent studies have presented the interpretation of thermodynamic enthalpy for the mass of BTZ black holes and the corresponding Smarr formula. All these are made in the background…
Infinite Volume of Noncommutative Black Hole Wrapped by Finite Surface
Baocheng Zhang, Li You
The volume of a black hole under noncommutative spacetime background is found to be infinite, in contradiction with the surface area of a black hole, or its Bekenstein-Hawking (BH)…
The mass formula for an exotic BTZ black hole
Baocheng Zhang
An exotic Banados-Teitelboim-Zanelli (BTZ) black hole has an angular momentum larger than its mass in three dimension (3D), which suggests the possibility that cosmic censorship co…
Influence of separating distance between atomic sensors for gravitational wave detection
Biao Tang, Baocheng Zhang, Lin Zhou +2
We consider a recent scheme of gravitational wave detection using atomic interferometers as inertial sensors, and reinvestigate its configuration using the concept of sensitivity f…
Entropy in the interior of a black hole and thermodynamics
Baocheng Zhang
Based on a recent proposal for the volume inside a black hole, we calculate the entropy associated with this volume and show that such entropy is proportional to the surface area o…
Correlation, entropy, and information transfer in black hole radiation
Baocheng Zhang, Qingyu Cai, Mingsheng Zhan +1
Since the discovery of Hawking radiation, its consistency with quantum theory has been widely questioned. In the widely described picture, irrespective of what initial state a blac…
Configurations of a new atomic interferometer for gravitational wave detection
Biao Tang, Baocheng Zhang, Lin Zhou +2
Recently, the configuration using atomic interferometers (AIs) had been suggested for the detection of gravitational waves. A new AI with some additional laser pulses for implement…
Information conservation is fundamental: recovering the lost information in Hawking radiation
Baocheng Zhang, Qing-yu Cai, Ming-sheng Zhan +1
In both classical and quantum world, information cannot appear or disappear. This fundamental principle, however, is questioned for a black hole, by the acclaimed "information loss…
Towards experimentally testing the paradox of black hole information loss
Baocheng Zhang, Qing-yu Cai, Ming-sheng Zhan +1
Information about the collapsed matter in a black hole will be lost if Hawking radiations are truly thermal. Recent studies discover that information can be transmitted from a blac…
Entropy Conservation in the Transition of Schwarzschild-de Sitter space to de Sitter space through tunneling
Baocheng Zhang, Qing-yu Cai, Ming-sheng Zhan
We revisit the Parikh-Wilczek tunneling through the de Sitter horizon and obtain the tunneling rate in Schwarzschild-de Sitter space, which is non-thermal and closely related to th…
