A theory is presented to calculate the heat dissipation of a magnetic suspension, a ferrofluid, driven by7 circularly polarized magnetic field. Theory is tested by in vitro experiments and it is shown that, regardless of the character of the relaxation process, linearly and circularly polarized magnetic field excitations, having the same root-mean-square magnitude, are equivalent in terms of heating efficiency.

Nonlinear Seebeck and Peltier effects in quantum point contacts Çipiloğlu, Mustafa A; Turgut, Sadi; Tomak, Mehmet (Wiley, 2004-09-01) The charge and entropy currents across a quantum point contact are expanded as a series in powers of the applied bias voltage and the temperature difference. After that, the expansions of the Seebeck voltage in temperature difference and the Peltier heat in current are obtained. With a suitable choice of the average temperature and chemical potential, the lowest order nonlinear term in both cases appear to be of third order. The behavior of the third-order coefficients in both cases are then investigated fo...
Temperature dependence of the polarization and tilt angle under an electric field close to the smectic AC* phase transition in a ferroelectric liquid crystal Yurtseven, Hasan Hamit (Informa UK Limited, 2008-01-01) The temperature dependence of the polarization P and the tilt angle theta is calculated here in the presence of a constant electric field near the smectic AC* phase transition of a ferroelectric liquid crystal using a mean field model. We demonstrate here the temperature dependence of P and theta under some fixed electric fields for the ferroelectric liquid crystal of 4-(3-methyl-2-chlorobutanoyloxy)-4'-heptyloxybiphenyl. Our predicted values of P and theta at various temperatures under fixed electric field...
ELECTRON POLARIZATION IN QUANTUM-WELLS WITH UNIFORM ELECTRIC-FIELD ILAIWI, KF; Tomak, Mehmet (Wiley, 1991-08-01) The polarization of a quantum electron confined in square, parabolic, and triangular quantum wells is calculated numerically. The aim of the present calculations is to compare the results for various geometries.
Investigation of structural, electronic, magnetic and lattice dynamical properties for XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds Surucu, Gokhan; IŞIK, MEHMET; CANDAN, ABDULLAH; Wang, Xiaotian; Güllü, Hasan Hüseyin (Elsevier BV, 2020-06-15) Structural, electronic, magnetic, mechanical and lattice dynamical properties of XCoBi (X: Ti, Zr, Hf) Half-Heusler compounds have been investigated according to density functional theory and generalized gradient approximation. Among alpha, beta and gamma structural phases, gamma-phase structure has been found as the most stability characteristics depending on the calculated formation enthalpies, energy-volume dependencies and Cauchy pressures. Energy-volume plots of possible magnetic orders of gamma-phase ...
Nonlinear intersubband optical absorption of Si delta-doped GaAs under an electric field Yildirim, Hasan; Tomak, Mehmet (Wiley, 2006-10-01) We study the nonlinear intersubband optical absorption of a single Si delta-doped GaAs sheet placed in the middle of a GaAs quantum well and subjected to an electric field. The Schrodinger and Poisson equations are solved self-consistently for various electric field strengths. The self-consistent solutions provide us with the correct confining potential, the wave functions, the corresponding subband energies and the subband occupations. The nonlinear optical intersubband absorption spectra are discussed wit...
