Passive approximation and optimization using B-splines
Yevhen Ivanenko, Mats Gustafsson, B. L. G. Jonsson +4
A passive approximation problem is formulated where the target function is an arbitrary complex valued continuous function defined on an approximation domain consisting of a finite…
On the natural modes of helical structures
Sven Nordebo, Mats Gustafsson, Gerhard Kristensson +3
Natural modes of helical structures are treated by using the periodic dyadic Green's functions in cylindrical coordinates. The formulation leads to an infinite system of one-dimens…
Dispersion modeling and analysis for multilayered open coaxial waveguides
Sven Nordebo, Gokhan Cinar, Stefan Gustafsson +1
This paper presents a detailed modeling and analysis regarding the dispersion characteristics of multilayered open coaxial waveguides. The study is motivated by the need of improve…
Photon flux and distance from the source: consequences for quantum foundations and technologies
Andrei Khrennikov, Börje Nilsson, Sven Nordebo +1
The paper explores the fundamental physical principles of quantum mechanics (in fact, quantum field theory) which limit the bit rate for long distances. Propagation of photons in o…
Fisher Information for Inverse Problems and Trace Class Operators
Sven Nordebo, Mats Gustafsson, Andrei Khrennikov +2
This paper provides a mathematical framework for Fisher information analysis for inverse problems based on Gaussian noise on infinite-dimensional Hilbert space. The covariance oper…
Classical signal model reproducing quantum probabilities for single and coincidence detections
Andrei Khrennikov, Börje Nilsson, Sven Nordebo
We present a simple classical (random) signal model reproducing Born's rule. The crucial point of our approach is that the presence of detector's threshold and calibration procedur…
Decompositions of Gelfand-Shilov kernels into kernels of similar class
Joachim Toft, Andrei Khrennikov, Börje Nilsson +1
We prove that any linear operator with kernel in a Gelfand-Shilov space is a composition of two operators with kernels in the same Gelfand-Shilov space. We also give links on numer…
Bounds for the Distance Dependence of Correlation Functions of Entangled Photons in Waveguides
Andrei Khrennikov, Borje Nilsson, Sven Nordebo +1
The distance dependence of the probability of observing two photons in a waveguide is investigated. The Glauber correlation functions of the entangled photons in waveguides are con…
Scattering in quantum tubes
B. Nilsson
It is possible to fabricate mesoscopic structures where at least one of the dimensions is of the order of de Broglie wavelength for cold electrons. By using semiconductors, compose…
