Xiangdong Zhang of Beijing Normal University and Zhengyou Liu of Wuhan University have used computer simulations to design two-dimensional phononic crystals that behave like the "left-handed" optical materials that are able to negatively refract light ( Appl. Phys. Lett. 85 341 ). They believe that the phenomenon could lead to applications in acoustics, seismology and ultrasonics." - From PhysicsWeb kaixuan ·¢±íÓÚ 02:49 | ÔĶÁÈ«ÎÄ | ÆÀÂÛ(0) | ÒýÓÃTrackback(0) | ±à¼­ 2004-06-05 10:34 ÄÉÃ×µÆ¹Ü -[ÖлªÎïÀí] ×Ô´Ó125ÄêÇ°°®µÏÉú·¢Ã÷µçµÆÒÔÀ´,µÆ¹ÜµÄÖÆ×÷²¢Ã»ÓкܴóµÄ¸Ä±ä.È»¶ø×î½üÖйúÇ廪´óѧµÄÑо¿ÈËÔ±·¢Ã÷ÁËÓÃ̼ÄÉÃ׹ܵÆË¿ÖÆ×÷µÄµÆ¹Ü,ÕâÖֵƹܱȴ«Í³µÆ¹ÜÓкܶ෽ÃæµÄÓÅÔ½ÐÔ.ÕâÖֵƹܹÀ¼ÆÄÜÔÚÎåÄêÖ®ÄÚÉÏÊС£ ÏûÏ¢À´Ô´: Nanobulbs make their debut .

However, the team behind the CDMS II (Cryogenic Dark Matter Search) experiment -- which is four times more sensitive than other dark-matter detectors -- hope to improve the sensitivity of the experiment by another factor of 20 over the next few years ( arXiv.org/abs/astro-ph/0405033 ). The detection of a dark matter particle would represent a major breakthrough in both particle physics and cosmology."
