A modified version of panspermia theory, named Nebula-Relay hypothesis or local panspermia, is introduced to explain the origin of life on Earth. Primitive life, acting as the seed…
Pattern formation in a driven Bose-Einstein Condensate
Zhendong Zhang, Kai-Xuan Yao, Lei Feng +2
Pattern formation is ubiquitous in nature from morphogenesis and cloud formation to galaxy filamentation. More often than not, patterns arise in a medium driven far from equilibriu…
