Phase Operator Problem and Macroscopic Extension of Quantum Mechanics [PDF]

, 1997
To find the Hermitian phase operatorof a single-mode electromagnetic field in quantum mechanics, the Schroedinger representation is extended to a larger Hilbert space augmented by states with infinite excitation by nonstandard analysis.

A theorem on the absence of phase transitions in one-dimensional growth models with onsite periodic potentials [PDF]

, 2001
We rigorously prove that a wide class of one-dimensional growth models with onsite periodic potential, such as the discrete sine-Gordon model, have no phase transition at any temperature $T>0$.

2-D Prony-Huang Transform: A New Tool for 2-D Spectral Analysis [PDF]

, 2014
This work proposes an extension of the 1-D Hilbert Huang transform for the analysis of images. The proposed method consists in (i) adaptively decomposing an image into oscillating parts called intrinsic mode functions (IMFs) using a mode decomposition ...

Why is Landau-Ginzburg link cohomology equivalent to Khovanov homology?

Journal of High Energy Physics, 2019
In this note we make an attempt to compare a cohomological theory of Hilbert spaces of ground states in the N = 2 2 $$ \mathcal{N}=\left(2,2\right) $$ 2d Landau-Ginzburg theory in models describing link embeddings in ℝ3 to Khovanov and Khovanov-Rozansky ...

Seismic Wave Propagation Characteristics and Their Effects on the Dynamic Response of Layered Rock Sites

Applied Sciences, 2022
To investigate the seismic response of layered rock sites, a multidomain analysis method was proposed. Three finite element models with infinite element boundaries for layered sites were analysed.

Simple planar Bragg grating devices for photonic Hilbert transform

, 2010
Hilbert transformers are important devices widely used in information processing and signal analysis in the electronic domain. For example, for spectral efficiency improvement, it is used to construct the analytic signal for single sideband (SSB ...

Quantum walks with an anisotropic coin I: spectral theory [PDF]

, 2017
We perform the spectral analysis of the evolution operator U of quantum walks with an anisotropic coin, which include one-defect models, two-phase quantum walks, and topological phase quantum walks as special cases.

The elliptic sinh-Gordon equation in a semi-strip

Advances in Nonlinear Analysis, 2017
We study the elliptic sinh-Gordon equation posed in a semi-strip by applying the so-called Fokas method, a generalization of the inverse scattering transform for boundary value problems.
