In the centenary year of Einstein's General Theory of Relativity, this paper reviews the current status of gravitational wave astronomy across a spectrum which stretches from attohertz to kilohertz frequencies. Sect. 1 of this paper reviews the historical development of gravitational wave astronomy from Einstein's first prediction to our current understanding the spectrum. It is shown that detection of signals in the audio frequency spectrum can be expected very soon, and that a north-south pair of next generation detectors would provide large scientific benefits. Sect. 2 reviews the theory of gravitational waves and the principles of detection using laser interferometry. The state of the art Advanced LIGO detectors are then described. These detectors have a high chance of detecting the first events in the near future. Sect. 3 reviews the KAGRA detector currently under development in Japan, which will be the first laser interferometer detector to use cryogenic test masses. Sect. 4 of this paper reviews gravitational wave detection in the nanohertz frequency band using the technique of pulsar timing. Sect. 5 reviews the status of gravitational wave detection in the attohertz frequency band, detectable in the polarisation of the cosmic microwave background, and discusses the prospects for detection of primordial waves from the big bang. The techniques described in sects. 1-5 have already placed significant limits on the strength of gravitational wave sources. Sects. 6 and 7 review ambitious plans for future space based gravitational wave detectors in the millihertz frequency band. Sect. 6 presents a roadmap for development of space based gravitational wave detectors by China while sect. 7 discusses a key enabling technology for space interferometry known as time delay interferometry. gravitational waves, ground based detectors, pulsar timing, spaced based detectors, CMB PACS number(s): 04.80.

“…16 by Hulse and Taylor in 1974 [4] indirectly confirm the existence of a gravitational wave. In order to directly detect a gravitational wave, people are launching huge detection projects for gravitational waves, such as LIGO [5], Virgo [6], GEO600 [7], KAGRA [8], AIGO [9], eLISA [10,11], etc. An atomic interferometer is even designed for the detection of gravitational waves [12][13][14][15].…”

Classical harmonic vibrations with micro amplitudes and low frequencies monitored by quantum entanglement

We study the entanglement dynamics of the two two-level atoms coupled with a single-mode polarized cavity field after incorporating the decoupled atomic centers of mass classical harmonic vibrations with micro amplitudes and low frequencies. We discover a new quantum mechanical measurement effect for the entanglement dynamics. We propose a quantitative vibrant factor to modify the concurrence of the two atomic states. When the vibrant frequencies are very low, we obtain that:(1) the factor depends on the relative vibrant displacements and the initial phases rather than the absolute amplitudes, and reduces the concurrence to three orders of magnitude;(2) the concurrence increases with the increase of the initial phases; (3) the frequency of the harmonic vibration can be obtained by measuring the maximal value of the concurrence during a small measurement time. These results indicate that the extremely weak classical harmonic vibrations can be monitored by the entanglement of quantum states. The effect reported in the paper always works well as long as the internal degrees of freedom of the system (regardless of unitary evolution or non-unitary evolution with time) are decoupled with the external classical harmonic vibrations of atomic centers of mass.

“…Polydimethylsiloxane (PDMS, Sylgard 184 Silicone Elastomer KIT, Dow Corning) is a silicon-based organic polymer and is one of most popular materials for creating microfluidic channels, elastic stamps, and flexible electronics. [1][2][3][4][5][6][7][8][9][10][11][12] PDMS displays several advantages including optical transparency, gas permeability, and biocompatibility, and such properties facilitate its extensive application in the biological and medical fields. [13][14][15][16][17][18][19][20] The typical process to construct the PDMS microfluidic channels is the preparation of master mold, PDMS replication from a master mold and bonding.…”

Leftover uncured polydimethylsiloxane (PDMS) polymer is generally discarded. In an effort to minimize this waste, we have developed a method for cryo-preserving PDMS prepolymer involving a simple storage technique for the preservation and repeated use over 1 month. Aliquots of the uncured PDMS prepolymer were stored at 220 or 280 C, then conveniently and easily thawed at body temperature (37 C). Proposed cryo-preservation was successfully evaluated using diverse biological and physical tests.This method of cryo-preserving PDMS reduces both the material waste and labor of soft lithography process and may enable soft lithography to be environmentally friendly relative to previous methods. The method may be popularly accepted for application to a variety of common microdevice fabrication procedures.
