Supersymmetric minisuperspace models in self-dual loop quantum cosmology
Journal of High Energy Physics, 2021 In this paper, we study a class of symmetry reduced models of N $$ \mathcal{N} $$ = 1 super- gravity using self-dual variables. It is based on a particular Ansatz for the gravitino field as proposed by D’Eath et al. We show that the essential part of the

Quantum Reports, 2022 We recently proposed that topological quantum computing might be based on SL(2,C) representations of the fundamental group π1(S3\K) for the complement of a link K in the three-sphere.

Krylov complexity and spectral form factor for noisy random matrix models
Journal of High Energy Physics, 2023 We study the spectral properties of two classes of random matrix models: non-Gaussian RMT with quartic and sextic potentials, and RMT with Gaussian noise. We compute and analyze the quantum Krylov complexity and the spectral form factor for both of these

Observational signatures of quantum gravity in interferometers [PDF]
Physics Letters B, 2019 We consider the uncertainty in the arm length of an interferometer due to metric fluctuations from the quantum nature of gravity, proposing a concrete microscopic model of energy fluctuations in holographic degrees of freedom on the surface bounding a ...

An experiment for observing quantum gravity phenomena using twin table-top 3D interferometers [PDF]
Classical and quantum gravity, 2020 Theories of quantum gravity based on the holographic principle predict the existence of quantum fluctuations of distance measurements that accumulate and exhibit correlations over macroscopic distances.

Signatures of the quantum nature of gravity in the differential motion of two masses [PDF]
Quantum Science and Technology, 2021 We show that a signature of the quantum nature of gravity is the quantum mechanical squeezing of the differential motion of two identical masses with respect to their common mode.

Frontiers in Astronomy and Space Sciences, 2021 In this review, we investigate the question of backreaction in different approaches to cosmological perturbation theory, and with a special focus on quantum theoretical aspects. By backreaction we refer here to the effects of matter field or cosmological

The Unexpected Fractal Signatures in Fibonacci Chains
Fractal and Fractional, 2019 In this paper, a new fractal signature possessing the cardioid shape in the Mandelbrot set is presented in the Fourier space of a Fibonacci chain with two lengths, L and S, where L / S = ϕ . The corresponding pointwise dimension is 1.7.
