Symmetries of κ-Minkowski space-time: a possibility of exotic momentum space geometry?
The quest for a quantum gravity phenomenology has inspired a quantum notion of space-time, which motivates us to study the fate of the relativistic...

Continuous percolation in a Hilbert space for a large system of qubits
The development of percolation theory was historically shaped by its numerous applications in various branches of science, in particular in...

Burns space and holography
We elaborate on various aspects of our top-down celestial holographic duality wherein the semiclassical bulk spacetime is a 4d asymptotically flat,...

Classification of gravitational waves in higher-dimensional space-time and possibility of observation
The direct detection of gravitational waves opens the possibility to test general relativity and its alternatives in the strong field regime. Here we...

On Graviton Propagation in Curved Space-Time Background
AbstractEquation describing propagation of gravitational waves (GW) over arbitrary curved space-time background is analyzed. New terms, which are...

Renormalized stress-energy tensor on global anti-de Sitter space-time with Robin boundary conditions
We study the renormalized stress-energy tensor (RSET) for a massless, conformally coupled scalar field on global anti-de Sitter space-time in four...

Lorentz Transformation Under a Discrete Dynamical Time and Continuous Space
The Lorentz transformation of space and time between two reference frames is one of the pillars of the special relativity theory. As a result of the...

Metric-Affine Theories of Gravity
General Relativity is not the end of the story. Several issues, ranging from Quantum Gravity to the Dark Side of the Universe need to be addressed in...

Response of a Canonical Ensemble of Quantum Oscillators to a Random Metric
We calculate the susceptibility of a canonical ensemble of quantum oscillators to the singular random metric. If the covariance of the metric is

Trace anomaly and induced action for a metric-scalar background
The conformal anomaly and anomaly-induced effective action represent useful and economic ways to describe semiclassical contributions to the action...

The Hilbert space of de Sitter quantum gravity
We obtain solutions of the Wheeler-DeWitt equation with positive cosmological constant for a closed universe in the large-volume limit. We argue that...

Solar Energetic Particles and Intensity of Metric Type II Radio Bursts
We perform a statistical analysis of 112 proton events from 24 November 2000 to 20 December 2014, accompanied by an increase in the intensity of...

Holographic Fisher information metric in Schrödinger spacetime
In this paper, we study the Fisher information metric on the space of the coupling constants on both sides of the duality between non-relativistic...

Aspects of three-dimensional C-metric
In this work, we present an extensive analysis of the thermodynamics and holographic properties of three-dimensional C-metrics in the FG gauge, where...

Cosmological Models with Bianchi Type V Metric
Within the framework of General relativity, two cosmological models are constructed for type V metric according to the Bianchi classification. In the...

Symplectic Reduction of Classical Mechanics on Shape Space
One of the foremost goals of research in physics is to find the most basic and universal theories that describe our universe. Many theories assume...

The ambient space formalism
We present a new formalism to solve the kinematical constraints due to Weyl invariance for CFTs in curved backgrounds and/or non-trivial states, and...

A novel probe of Einstein-Hilbert action: Dynamic upgradation of metric parameters
The Einstein-Hilbert (EH) action is peculiar in many ways. Some of the Peculiar features have already been highlighted in literature. In the present...
