Gamma-protocol for secure transmission of information
R. Shakhmuratov, A. Zinnatullin, F. Vagizov
Secure communication that allows only the sender and intended recipient of a message to view its content has a long history. Quantum objects, such as single photons are ideal carri…
Powder vibration studied by Mössbauer spectroscopy
A. L. Zinnatullin, R. N. Shakhmuratov, F. G. Vagizov
Mössbauer spectroscopy is applied to study ultrasound vibration of a granular material. A pile of powder is placed onto the surface of piezo transducer vibrated with the frequency…
Application of Mössbauer spectroscopy to study vibrations of a granular medium excited by ultrasound
R. N. Shakhmuratov, F. G. Vagizov
It is shown that analysis of Mössbaur spectra of a granulated medium, immersed into the epoxy resin without hardener, allows to study mechanical vibrations of granules. In our expe…
Defect charging and resonant levels in half-Heusler NbTiFeSb
Yefan Tian, Farit G. Vagizov, Nader Ghassemi +5
We report Nb and Sb NMR and Fe Mössbauer studies combined with DFT calculations of NbTiFeSb (), one of the most promisi…
Observation of acoustically induced transparency for gamma-ray photons
Y. V. Radeonychev, I. R. Khairulin, F. G. Vagizov +1
We report an observation of a 148-fold suppression of resonant absorption of 14.4-keV photons from exp(-5.2) to exp(-0.2) with preservation of their spectral and temporal character…
Time-delayed coincidence technique for subnatural-width spectroscopy as an interference phenomenon
R. N. Shakhmuratov, F. G. Vagizov
Single photon, emitted in a transition between two states, has a frequency distribution of intensity, which is given by Lorentzian if the transition is only naturally broadened and…
