On Evolutes of Null Cartan Curves in Minkowski 4-Space

Journal of New Theory, 2021
This paper aims to discuss the theory of evolutes of null Cartan curves in Minkowski 4-space. In the second part, we present the basic concepts of curves in Minkowski 4-space with its Frenet equations.

The dual conformal box integral in Minkowski space

Nuclear Physics B, 2021
The dual conformal box integral in Minkowski space is not fully determined by the conformal invariants z and z¯. Depending on the kinematic region its value is on a ‘branch’ of the Bloch-Wigner function which occurs in the Euclidean case.

Conformal Symmetry and Supersymmetry in Rindler Space

Universe, 2020
This paper addresses the fate of extended space-time symmetries, in particular conformal symmetry and supersymmetry, in two-dimensional Rindler space-time appropriate to a uniformly accelerated non-inertial frame in flat 1+1-dimensional space-time ...

dS-AdS structures in the non-commutative Minkowski spaces [PDF]

Theor.Math.Phys. 144 (2005) 1315-1343; Teor.Mat.Fiz. 144 (2005) 513-543, 2004
We consider a family of non-commutative 4d Minkowski spaces with the signature (1,3) and two types of spaces with the signature (2,2). The Minkowski spaces are defined by the common reflection equation and differ in anti-involutions. There exist two Casimir elements and the fixing of one of them leads to non-commutative "homogeneous" spaces $H_3 ...

Brownian Motion in Minkowski Space

Entropy, 2015
We construct a model of Brownian motion in Minkowski space. There are two aspects of the problem. The first is to define a sequence of stopping times associated with the Brownian “kicks” or impulses.

Quantum Complex Minkowski Space [PDF]

, 2005
The complex Minkowski phase space has the physical interpretation of the phase space of the scalar massive conformal particle. The aim of the paper is the construction and investigation of the quantum complex Minkowski space.

Entanglement in Unruh, Hawking, and Cherenkov radiation from a quantum optical perspective

Physical Review Research, 2022
Free quantum field theory in flat space-time is often believed to be well established, holding no surprises. We hope, by the end of this paper, to have demonstrated that surprises still exist.

Celestial holography and AdS 3/CFT 2 from a scaling reduction of twistor space

Journal of High Energy Physics, 2023
Celestial amplitudes obtained from Mellin transforming 4d momentum space scattering amplitudes contain distributional delta functions, hindering the application of conventional CFT techniques.

Vacuum thermal effects in flat space-time from conformal quantum mechanics

Journal of High Energy Physics, 2021

Orlicz Mean Dual Affine Quermassintegrals

Journal of Function Spaces, 2018
Our main aim is to generalize the mean dual affine quermassintegrals to the Orlicz space. Under the framework of dual Orlicz-Brunn-Minkowski theory, we introduce a new affine geometric quantity by calculating the first Orlicz variation of the mean dual ...
