摘要：
The fundamental strong interaction at low-energy scale is very essential to
understand important pieces of the Nature, from nuclei to pulsars, but is
still challenging physicists although it is a mathematically well-defined
domain. The inner structure of pulsar-like compact stars (or the equation of
state of cold matter at supra-nuclear density) is still hotly debated even
nearly half a century after the discovery of pulsars. In this talk, we
propose that pulsars could be condensed object of quark clusters via residual
color interaction, and such a quark-cluster star distinguishes from
conventional both neutron and quark stars.
