A Simplified Calculation for the Fundamental Solution to the Heat Equation on the Heisenberg Group

Albert Boggess, Andrew Raich

Let $L = - 1/4 (\sum_{j = 1}^{n} (X_{j}^{2} + Y_{j}^{2}) + iγ T)$ where $γ$ is a complex number, $X_{j}$ , $Y_{j}$ , and $T$ are the left invariant vector fields of the Heisenberg group structure for $R^n…

Resonance fluorescence from a coherently driven semiconductor quantum dot in a cavity

Andreas Muller, Edward B. Flagg, Pablo Bianucci +7

We show that resonance fluorescence, i.e. the resonant emission of a coherently driven two-level system, can be realized with a semiconductor quantum dot. The dot is embedded in a…

On Magnetic Interlayer Coupling and Proximity Effect in a La $_{0.67}$ Ca $_{0.33}$ MnO $_{3}$ (10 nm)/YBa $_{2}$ Cu $_{3}$ O $_{7}$ (10 nm) Superlattice

J. W. Freeland, J. Chakhalian, G. Cristiani +2

We present a study of interlayer coupling and proximity effects in a La $_{0.66}$ Ca $_{0.33}$ MnO $_{3}$ (10 nm)/YBa $_{2}$ Cu $_{3}$ O $_{7}$ (10 nm) superlattice. Using element-sensitive x-ray prob…

Theoretical phase diagram of ultrathin films of incipient ferroelectrics

A. R. Akbarzadeh, L. Bellaiche, Jorge Íñiguez +1

We have used a first-principles-based scheme to compute the temperature-versus-misfit strain ``Pertsev'' phase diagram of ultrathin films of {\sl incipient} ferroelectric KTaO $_{3}$ .…

Knot exteriors with additive Heegaard genus and Morimoto's Conjecture

Tsuyoshi Kobayashi, Yo'av Rieck

Given integers g_i > 1 (i=1,...,n) we prove that there exist infinitely may knots K_i in S^3 so that g(E(K_i)) = g_i and the Heegaard genus of the exterior of the connected sum of…

Beta-NMR of Isolated Lithium in Nearly Ferromagnetic Palladium

T. J. Parolin, Z. Salman, J. Chakhalian +13

The temperature dependence of the frequency shift and spin-lattice relaxation rate of isolated, nonmagnetic Li-8 impurities implanted in a nearly ferromagnetic host (Pd) are measur…
