Segregation in spatially structured cities
Diego Ortega, Javier Rodríguez-Laguna, Elka Korutcheva
Half of the world population resides in cities and urban segregation is becoming a global issue. One of the best known attempts to understand it is the Schelling model, which consi…
A Schelling Extended Model in Networks -- Characterization of Ghettos in Washington D.C
Diego Ortega, Elka Korutcheva
Segregation affects millions of urban dwellers. The main expression of this reality is the creation of ghettos which are city parts characterized by a combination of features: low…
Possible zero sound in layered perovskites with ferromagnetic - exchange interaction
Todor M. Mishonov, Nedelcho I. Zahariev, Hassan Chamati +1
We analyze the conditions for observation of zero sound in layered perovskites with transition metal ion on chalcogenide oxidizer. We conclude that propagation of zero sound is pos…
Hot spots along the Fermi contour of high- cuprates analyzed by - exchange interaction
Todor M. Mishonov, Nedelcho I. Zahariev, Hassan Chamati +1
We perform a thorough theoretical study of the electron properties of a generic CuO plane in the framework of Shubin-Kondo-Zener - exchange interaction that simultaneousl…
Set-up for observation thermal voltage noise and determination of absolute temperature and Boltzmann constant
Todor M Mishonov, Nikola S Serafimov, Emil G Petkov +1
We describe a set-up for measurement of the absolute zero by Johnson-Nyquist thermal noise which can be performed within a week in every high-school or university. Necessary electr…
Control of a qubit state by a soliton propagating through a Heisenberg spin chain
S. Varbev, I. Boradjiev, R. Kamburova +1
We demonstrate that nonlinear magnetic solitary excitations (solitons) traveling through a Heisenberg spin chain may be used as a robust tool capable of coherent control of the qub…
