Stochastic quantization on Lorentzian manifolds

Journal of High Energy Physics, 2021
We embed Nelson’s theory of stochastic quantization in the Schwartz-Meyer second order geometry framework. The result is a non-perturbative theory of quantum mechanics on (pseudo-)Riemannian manifolds.

Solar active-sterile neutrino conversion with atomic effects at dark matter direct detection experiments

Journal of High Energy Physics, 2022
The recent XENON1T excess can be explained by the solar active-sterile neutrino conversion with bound electrons via light mediator. Nevertheless, the atomic effects are usually omitted in the solar neutrino explanations.

Spectral action and heat kernel trace for Ricci flat manifolds from stochastic flow over second quantized $L^2$-differential forms

, 2023
A quantum stochastic differential equation (qsde) on Fock space over $L^2$ differential 1-forms is given from the small "time" flow of which the trace of the connection Laplacian heat kernel for the spinor endomorphism bundle can be computed over any compact Ricci-flat Riemannian manifold. The existence of the stochastic flow is established by adapting

Design and Experiments of a Two-Stage Fuzzy Controller for the Off-Center Steer-by-Wire System of an Agricultural Mobile Robot

Machines, 2023
This paper focuses on the steering motion control of an in-wheel motor-drive robot. The influence of the pulse-width modulation (PWM) duty cycle on steering motion and the steering control method have not yet been proved. Thus, this study aimed to design

On a Problem Arising in Application of the Re-Quantization Method to Construct Asymptotics of Solutions to Linear Differential Equations with Holomorphic Coefficients at Infinity

Mathematical and Computational Applications, 2019
The re-quantization method—one of the resurgent analysis methods of current importance—is developed in this study. It is widely used in the analytical theory of linear differential equations.

Differential neural networks observer for second order systems with sampled and quantized output

IFAC-PapersOnLine, 2018
Abstract Real instrumentation of control systems in digital devices introduces the necessity of considering quantization and sampling information used in the control and estimator design. The aim of this study is designing a state estimator for uncertain second order nonlinear systems based on the approximation enforced by differential neural ...

Spin-resolved transport physics induced by a Majorana-fermion zero mode

AIP Advances, 2019
By using the Hubbard operator Green’s function method, the spin-resolved transport properties of a quantum dot coupled to metallic leads and side-coupled to a topological superconductor wire hosting Majorana bound states (MBSs) are studied theoretically.

spo(2|2)-Equivariant Quantizations on the Supercircle S^{1|2}

Symmetry, Integrability and Geometry: Methods and Applications, 2013
We consider the space of differential operators $mathcal{D}_{lambdamu}$ acting between$lambda$- and $mu$-densities defined on $S^{1|2}$ endowed with its standard contact structure.This contact structure allows one to define a filtration on $mathcal{D}_ ...
