The scattering diagram of a stock index results in a complex network structure, which can be used to analyze the viscoelastic properties of the index. The change along x-or y-direction of the diagram corresponds to purely elastic (or spring like) movement whereas the diagonal change at an angle of 45 degrees corresponds to purely viscous (or dashpot like) movement. The viscous component pushes the price from its current value to any other value, while the elastic component acts like a restoring force. Four indices, namely, DJI, S&P-500, NASDAQ-100, and NASDAQ-composite were studied for the period of 2001-2009. NASDAQ-composite displayed very high elasticity while NASDAQ-100 displayed the highest fluidity in the time period considered. The fluidity of DJI and S&P-500 came out to be close to each other, and they are almost the same in the second half of the period.

Oscillations in dc driven barrier discharges: Numerical solutions, stability analysis, and phase diagram SIJACIC, DD; EBERT, U; Rafatov, İsmail (American Physical Society (APS), 2005-06-01) A short gas-discharge layer sandwiched with a semiconductor layer between planar electrodes shows a variety of spatiotemporal patterns. We focus on the spontaneous temporal oscillations that occur while a dc voltage is applied and while the system stays spatially homogeneous; the results for these oscillations apply equally to a planar discharge in series with any resistor with capacitance. We define the minimal model, identify its independent dimensionless parameters, and then present the results of the fu...
Thermodynamics of Bose-Einstein gas trapped in D-dimensional quartic potentials Karabulut, Elife Oe; Koyuncu, Mustafa; Tomak, Mehmet (Elsevier BV, 2010-04-01) Quartic potentials play air important role in a broad range of fields in the Bose-Einstein Condensation (BEC) literature, from optical lattices to vortices and even to the quantum phase transitions. This also makes the study of thermodynamic properties of systems confined by these potentials interesting. For this purpose, the BEC of an ideal Bose system with a finite number of particles is considered in three and lower dimensions. A comprehensive thermodynamic analysis including the condensation temperature...
Power laws and Gaussians for stock market fluctuations Tuncay, Çağlar (Elsevier BV, 2007-01-15) The daily financial volume of transaction on the New York Stock Exchange and its day-to-day fluctuations are analysed with respect to power-law tails as well to their long-term trends. We also model the transition to a Gaussian distribution for longer time intervals, like months instead of days.
Viscoelasticity and pattern formations in stock market indices Gündüz, Güngör; Gunduz, Aydin (Springer Science and Business Media LLC, 2017-06-05) The viscoelastic and thermodynamic properties of four stock indices, namely, DJI, Nasdaq-100, Nasdaq-Composite, and S&P were analyzed for a period of 30 years from 1986 to 2015. The asset values (or index) can be placed into Aristotelian 'potentiality-actuality' framework by using scattering diagram. Thus, the index values can be transformed into vectorial forms in a scattering diagram, and each vector can be split into its horizontal and vertical components. According to viscoelastic theory, the horizontal...
Spatiotemporal patterns in a dc semiconductor-gas-discharge system: Stability analysis and full numerical solutions Rafatov, İsmail; EBERT, Ute (American Physical Society (APS), 2007-09-01) A system very similar to a dielectric barrier discharge, but with a simple stationary dc voltage, can be realized by sandwiching a gas discharge and a high-ohmic semiconductor layer between two planar electrodes. In experiments this system forms spatiotemporal and temporal patterns spontaneously, quite similarly to, e.g., Rayleigh-Benard convection. Here it is modeled with a simple discharge model with space charge effects, and the semiconductor is approximated as a linear conductor. In previous work, this ...
