Luttinger surgery and Kodaira dimension
Chung-I Ho, Tian-Jun Li
In this note we show that the Lagrangian Luttinger surgery preserves the symplectic Kodaira dimension. Some constraints on Lagrangian tori in symplectic four manifolds with non-pos…
Diffusive mixing of periodic wave trains in reaction-diffusion systems
Björn Sandstede, Arnd Scheel, Guido Schneider +1
We consider reaction-diffusion systems on the infinite line that exhibit a family of spectrally stable spatially periodic wave trains $u_0(kx-\om t;k)$ that are parameterized by th…
Giant microwave photoresistivity in a high-mobility quantum Hall system
A. T. Hatke, M. A. Zudov, L. N. Pfeiffer +1
We report the observation of a remarkably strong microwave photoresistivity effect in a high-mobility two-dimensional electron system subject to a weak magnetic field and low tempe…
Non-linear response of a high mobility two-dimensional electron system near the second harmonic of the cyclotron resonance
A. T. Hatke, M. A. Zudov, L. N. Pfeiffer +1
Recent experiments on microwave-irradiated high-mobility two-dimensional electron systems revealed a novel photoresistivity peak in the vicinity of the second cyclotron resonance h…
A Long, Cold, Early r-process? Neutrino-induced Nucleosynthesis in He Shells Revisited
P. Banerjee, W. C. Haxton, Y. -Z. Qian
We revisit a neutrino-driven r-process mechanism in the He shell of a core-collapse supernova, finding that it could succeed in early stars of metallicity < solar/1000, at relative…
Shape analysis of strongly-interacting systems: the heavy ion case
M. A. Lisa, E. Frodermann, G. Graef +4
Collisions between nuclei at ultrarelativistic energies produce a color-deconfined plasma that expands explosively and rapidly reverts to the color-confined (hadronic) state. In no…
