Spectrally narrow, long-term stable optical frequency reference based on a Eu$^{3+}$:Y$_{2}$SiO$_{5}$ crystal at cryogenic temperature
Spectrally narrow long-term stable optical frequency reference cryogenic temperature
2011/8/5
Abstract: Using an ultrastable continuous-wave laser at 580 nm we performed spectral hole burning of Eu$^{3+}$:Y$_{2}$SiO$_{5}$ at very high spectral resolution. Essential parameters determining the u...
Unprecedented High Long Term Frequency Stability with a Macroscopic Resonator Oscillator
Frequency Stability Resonator Oscillator
2010/11/16
This article reports on the long-term frequency stabilty characterisation of a new type of cryogenic sapphire oscillator using an autonomous pulse-tube cryocooler as its cold source. This new design e...
Energy localization on q-tori, long term stability and the interpretation of FPU recurrences
q-tori long term stability
2010/4/6
We focus on two approaches that have been proposed in recent years for the explanation of the so-called FPU paradox, i.e. the persistence of energy localization in the `low-q' Fourier modes of Fermi-P...

Accumulation and Long-Term Behavior of Radiocaesium in Tropical Plants
137Cs and 40K distributions Tropical trees
2010/10/13
The accumulation and distribution of 40K and 137Cs in tropical plant species were studied through measurements of gamma-ray spectra from mango, avocado, guava, pomegranate, chili pepper, papaya and ma...
