Enhancing ultraviolet spontaneous emission with a designed quantum vacuum: erratum.
We present a correction to parts of Fig. 5, Fig. 6 and Fig. 7, relating to the Purcell factors and Lamb shifts, due to an incorrect renormalization used in our custom Fortran code. The resulting corrections to some of the Q-factors are large, but do not affect the conclusions of the original manuscript.
متن کاملCharacteristics of Dual Amplified Spontaneous Emission from MEH-PPV Solutions
We report the observations of dual wavelength amplified spontaneous emission from the solutions of a conjugated polymer poly [2-methoxy-5-(2-ethylhexyloxy)-1, 4-phenylenevinylene] (MEH-PPV) in Tetrahydrofuran and 1, 2 Dichlorobenzene. We have prepared MEH-PPV using a modified procedure and purified several times in each step, the material offers low molecular weight, low polydispersity index an...
متن کاملAmplified Spontaneous Emission'
We review the coherence properties of the self-amplified spontaneous emission (SASE). Temporally, SASE is similar to the spontaneous undulator radiation except that the spectral bandwidth is about ten times narrower compared with typical undulator radiation. The situation is quite different in the transverse dimension, where SASE is fully coherent. INTRODUCTION Several laboratories are pursuing...
متن کاملExtreme Ultraviolet Emission from Neutron Stars
We summarize the detections of extreme ultraviolet (EUV) emission from neutron stars. Three rm detections have been made of spin-powered pulsars: the aged millisecond pulsar PSR J0437?4715, the middle-aged X-ray pulsar Geminga, and the radio pulsar PSR B0656+14. These observations allow us to evaluate both power-law and thermal-law emission models as the source of the EUV ux. For the case of PS...
متن کاملA Search for Ultraviolet Emission from LINERs
We have obtained Hubble Space Telescope Wide Field and Planetary Camera 2 ultraviolet (UV) 2200 Å and optical V -band images of 20 low-luminosity active galactic nuclei, most of which are spectroscopically classified as LINERs, in order to search for a possible photoionizing continuum. Six (30%) of the galaxies are detected in the UV. Two of the detected galaxies (NGC 3642 and NGC 4203) have co...
