The Life Cycle of Dust in the Universe: Observations, Theory, and Laboratory Experiments
The Life Cycle of Dust in the Universe Observations Theory Laboratory Experiments
2013/10/9
This meeting aims to address the life cycle of dust in the Universe, which covers the formation, evolution and destruction of dust in a range of environments, ranging from the smallest to the largest ...

Abstract: We demonstrate ultrafast resonant energy absorption of rare-gas doped He nanodroplets from intense few-cycle (~10 fs) laser pulses. We find that less than 10 dopant atoms "ignite" the drople...

We report a study on light force on a beam of neutral two-level atoms superimposed upon a few-cycle pulsed Gaussian laser field under both resonant and off-resonant condition. The phenomena of focusin...
A Coupled Quantum Otto Cycle
Coupled Quantum Otto Cycle
2010/11/8
We study the 1-d isotropic Heisenberg model of two spin-1/2 systems as a quantum heat engine. The engine undergoes a four-step Otto cycle where the two adiabatic branches involve changing the external...
Understanding the Cycle of Knowledge: Its rise, preservation and decay

2010/4/8
For a class of coupled limit cycle oscillators, we give a condition on a linear coupling operator that is necessary and sufficient for exponential stability of the synchronous solution. We show that w...
