Entropy and thermopower in the 2D t-J model
W. O. Putikka
The entropy of the two-dimensional - model is investigated using its 12th order high temperature series. A direct Padé extrapolation of the entropy series doesn't converge we…
Prediction of extremely long electron spin lifetimes at room temperature in wurtzite semiconductor quantum wells
N. J. Harmon, W. O. Putikka, R. Joynt
Many proposed spintronics devices require mobile electrons at room temperature with long spin lifetimes. One route to achieving this is to use quantum wells with tunable spin-orbit…
Theory of Electron Spin Relaxation in n-Doped Quantum Wells
N. J. Harmon, W. O. Putikka, R. Joynt
Recent experiments have demonstrated long spin lifetimes in uniformly n-doped quantum wells. The spin dynamics of exciton, localized, and conduction spins are important for underst…
Theory of Electron Spin Relaxation in ZnO
N. J. Harmon, W. O. Putikka, R. Joynt
Doped ZnO is a promising material for spintronics applications. For such applications, it is important to understand the spin dynamics and particularly the spin coherence of this I…
Broad Peak in the d_{x^2-y^2} Superconducting Correlation Length as a Function of Hole Concentration in the Two-Dimensional t-J Model
W. O. Putikka, M. U. Luchini
We have calculated high temperature series to 12th order in inverse temperature for singlet superconducting correlation functions of the 2D t-J model with s-, d_{x^2-y^2}- and d_xy…
Theory of Optical Orientation in n-Type Semiconductors
W. O. Putikka, R. Joynt
Time resolved measurements of magnetization in n-GaAs have revealed a rich array of spin decoherence processes, and have shown that fairly long lifetimes (\sim 100 ns) can be achie…
