Second-Order Conformally Equivariant Quantization in Dimension 1|2

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
This paper is the next step of an ambitious program to develop conformally equivariant quantization on supermanifolds. This problem was considered so far in (super)dimensions 1 and 1|1.

Geometric Quantization and Foliation Reduction [PDF]

open access: yes, 2013
A standard question in the study of geometric quantization is whether symplectic reduction interacts nicely with the quantized theory, and in particular whether “quantization commutes with reduction.” Guillemin and Sternberg first proposed ...

Analysis and Demonstration of the Quantile Vocoder [PDF]

open access: yes, 1986
A new scheme for speech compression is proposed, implemented and evaluated in this thesis. In this new scheme, the spectral envelope of the power spectral density of a speech frame is encoded using quartiles or order statistics.

Improving the Hardware Complexity by Exploiting the Reduced Dynamics-Based Fractional Order Systems

open access: yesIEEE Access, 2017
Fractional calculus is finding increased usage in the modeling and control of nonlinear systems with the enhanced robustness. However, from the implementation perspectives, the simultaneous modeling of the systems and the design of controllers with ...

Stochastic quantization of relativistic theories

open access: yes, 2021
It was shown recently that stochastic quantization can be made into a well defined quantization scheme on (pseudo-)Riemannian manifolds using second order differential geometry, which is an extension of the commonly used first order differential geometry.

Stochastic integral representations of second quantization operators

open access: yes, 2004
We give a necessary and sufficient condition for the second quantization operator Γ(h) of a bounded operator h on L2(R+), or for its differential second quantization operator λ(h), to have a representation as a quantum stochastic integral. This condition

A general theory of the second quantization methods

open access: yes, 1953
It is shown that the second quantization methods are a general mathematical technique applicable to formalisms involving linear equations of change, differential with respect to the time variable. The ordinary second quantization formalism for systems of

Triviality of the 2D stochastic Allen-Cahn equation [PDF]

open access: yes, 2012
We consider the stochastic Allen-Cahn equation driven by mollified space-time white noise. We show that, as the mollifier is removed, the solutions converge weakly to 0, independently of the initial condition.

On the solutions of the Schrödinger equation with 2nd Pöschl–Teller potentials

open access: yesResults in Physics
We delve into the intricacies of the hyperbolic Pöschl–Teller potential, often referred to as the 2nd Pöschl–Teller potential (PTP), and explore its implications on the Schrödinger equation for arbitrary l state case.
