The quantum group, Harper equation and the structure of Bloch eigenstates on a honeycomb lattice

, 2012
The tight-binding model of quantum particles on a honeycomb lattice is investigated in the presence of homogeneous magnetic field. Provided the magnetic flux per unit hexagon is rational of the elementary flux, the one-particle Hamiltonian is expressed ...

Probing Shock Properties with Non-thermal X-ray Filaments in Cas A [PDF]

, 2010
Thin non-thermal X-ray filaments are often seen in young supernova remnants. We used data from the 1 Ms Chandra observation of Cassiopeia A to study spectral properties of some of the filaments in this remnant.

High rate, fast timing Glass RPC for the high {\eta} CMS muon detectors

, 2016
The HL-LHC phase is designed to increase by an order of magnitude the amount of data to be collected by the LHC experiments. To achieve this goal in a reasonable time scale the instantaneous luminosity would also increase by an order of magnitude up to ...

Magnetic Rossby waves in the solar tachocline and Rieger-type periodicities

, 2009
Apart from the 11-year solar cycle, another periodicity around 155-160 days was discovered during solar cycle 21 in high energy solar flares, and its presence in sunspot areas and strong magnetic flux has been also reported.

Is very high energy emission from the BL Lac 1ES 0806+524 centrifugally driven?

, 2009
We investigate the role of centrifugal acceleration of electrons in producing the very high energy (VHE) radiation from the BL Lac object 1ES 0806+524, recently detected by VERITAS.

The Role of Physics in Science Integration [PDF]

, 2005
Special and General theories of relativity may be considered as the most significant examples of integrative thinking. From these works we see that Albert Einstein attached great importance to how we understand geometry and dimensions.

LITERARY FICTION AND REPRESENTATION OF HISTORY: GEORGIAN CASE STUDY [PDF]

, 2019
In the nineteenth century the process of history professionalization took place. It was characterized by exclusive development of the discipline. The “founding fathers” tried to bold the borderlines between the history and other disciplines and sharpen ...
