Tunable High-Q Resonator by General Impedance Converter
T. Mifune, T. M. Mishonov, N. S. Serafimov +6
For the need of measurements focused in condensed matter physics and especially Bernoulli effect in superconductors we have developed an active resonator with dual operational ampl…
On the Influence of the Ionization-Recombination Processes on Hydrogen Plasma Polytropic Index
Todor M. Mishonov, Iglika M. Dimitrova, Albert M. Varonov
The polytropic (adiabatic) index for pure hydrogen plasma is analytically calculated as function of reciprocal temperature and degree of ionization. Additionally, the polytropic in…
Sound Absorption in Partially Ionized Hydrogen Plasma and Heating Mechanism of Solar Chromosphere
Todor M. Mishonov, Iglika M. Dimitrova, Albert M. Varonov
The temperature dependence of rates of electron impact ionization and two electrons recombination are calculated using Wannier cross section of electron impact ionization of neutra…
The Day of the Inductance. Problem of the 7-th Experimental Physics Olympiad, Skopje, 7 December 2019
Todor M. Mishonov, Riste Popeski-Dimovsk, Leonora Velkoska +5
This is the problem of the 7-th international Experimental Physics Olympiad "The Day of the Inductance". A large inductance made by a general impedance converter is measured by the…
Measurement of the Boltzmann constant by Einstein. Problem of the 5-th Experimental Physics Olympiad. Sofia 9 December 2017
Todor M. Mishonov, Emil G. Petkov, Aleksander A. Stefanov +5
Several consecutive experiments with specifically built set-up are described. Performing of the consecutive experimental tasks enables possibility to determine Boltzmann's constant…
Determination of Boltzmann constant by equipartition theorem for capacitors
T. M. Mishonov, V. N. Gourev, I. M. Dimitrova +4
A new experimental set-up for Boltzmann constant measurement is described. Statistically averaged square of voltage is measured for different capacitances . B…
Measurement of the electron charge using Schottky noise. Problem of the 6-th Experimental Physics Olympiad. Sofia 8 December 2018
Todor M. Mishonov, Emil G. Petkov, Aleksander A. Stefanov +14
Several consecutive experiments are described with a printed circuit board PCB set-up, especially designed for these experiments. Doing the consecutive experimental tasks opens up…
Electrostatics of quadrupolarizable media
Radomir I. Slavchov, Iglika M. Dimitrova, Tzanko I. Ivanov
The classical macroscopic Maxwell equations are approximated. They are a corollary of the multipole expansion of the local electrostatic potential up to dipolar terms. But quadrupo…
Two Dimensional Polymerization of Graphene Oxide: Bottom-up Approach
Victor Atanasov, Stoyan Russev, Lyudmil Lyutov +9
We demonstrate a bottom-up synthesis of structures similar to graphene oxide via a two dimensional polymerization. Experimental evidence and discussion are conveyed as well as a ge…
