Overview of boldsymbol{bar{K} N} and boldsymbol{bar{K}}-nucleus dynamics

The main features of coupled-channel ${bar K}N$ dynamics near threshold and its repercussions in few-body $bar K$ -nuclear systems are briefly reviewed highlighting the I?=?1/2 ${bar K}NN$ system. For heavier nuclei, the extension of mean-field calculations to multi- $bar K$ nuclear quasibound states is discussed focusing on kaon condensation.
