Negative corrections to black hole entropy from string theory
We report for the first time that in heterotic string compactified on 4-torus or equivalently IIA string compactified on K3, the leading α ′...

Direct characteristic-function tomography of the quantum states of quantum fields
Herein, we propose a novel strategy for implementing a direct readout of the symmetric characteristic function of the quantum states of quantum...

Optical detection of quantum geometric tensor in intrinsic semiconductors
Quantum geometric tensor, including a symmetric real part defined as quantum metric and an antisymmetric part defined as Berry curvature, is...

Entropy of black holes with arbitrary shapes in loop quantum gravity
The quasi-local notion of an isolated horizon is employed to study the entropy of black holes without any particular symmetry in loop quantum...

A refined trans-Planckian censorship conjecture
We propose a refined version of trans-Planckian censorship conjecture (TCC), which could be elaborated from the strong scalar weak gravity conjecture...

Electron-Phonon Model in the Faddeev-Jackiw Quantization Formalism
The Faddeev and Jackiw procedure for the quantization of constrained gauge systems is used on the analysis of an interacting electron-phonon model...

Hawking Effect of AdS2 Black Holes in the Jackiw-Teitelboim Model
It might be tempting to consider that the two-dimensional anti-de Sitter black hole in the Jackiw-Teitelboim model is thermally hot by invoking the...

Crater-Hop**: Observing the Moon on Day 7: First Quarter
The double oblong crater Heraclitus with its northern half overlain by Licetus and its southeastern rim destroyed by Heraclitus D. The shallow bowl...

Bounds on Higgs and top quark masses from vacuum stability (degeneracy) with gravitational contributions
Based on the two-loop RGE of standard model gauge, top-Yukawa as well as scalar quartic couplings with full one-loop gravitational contributions in...

Immirzi parameter and quasinormal modes in four and higher spacetime dimensions
There is a one-parameter quantization ambiguity in loop quantum gravity, which is called the Immirzi parameter. In this paper, we fix this free...

Quantum corrections to the Hawking radiation spectrum
In 1995, Bekenstein and Mukhanov suggested that the Hawking radiation spectrum was discrete if the area spectrum was quantized in such a way that the...

Quantum cellular automata and free quantum field theory
In a series of recent papers [1–4] it has been shown how free quantum field theory can be derived without using mechanical primitives (including...

Influence of wall motion on particle sedimentation using hybrid LB-IBM scheme
We integrate the lattice Boltzmann method (LBM) and immersed boundary method (IBM) to capture the coupling between a rigid boundary surface and the...

Black hole entropy predictions without the Immirzi parameter and Hawking radiation of a single-partition black hole
By pointing out an error in the previous derivation of the area spectrum based on Ashtekar’s variables, we suggest a new area spectrum; instead of...

Repulsive gravitational effect of a quantum wave packet and experimental scheme with superfluid helium
We consider the gravitational effect of quantum wave packets when quantum mechanics, gravity, and thermodynamics are simultaneously considered. Under...

Planck-scale corrections to Friedmann equation
Recently, Verlinde proposed that gravity is an emergent phenomenon which originates from an entropic force. In this work, we extend Verlinde’s...

Hamiltonian reduction for Einstein’s equations in the (2+2) formalism
I apply the Hamiltonian reduction procedure to general spacetimes of 4 dimensions in the (2+2) formalism and find privileged spacetime coordinates in...

Can the Horowitz-Maldacena proposal be an alternative to the firewall?
Recently, there have been discussions that black hole complementarity is inconsistent and that the firewall is required to prohibit the observation...
