Renormalization to low energies is widely used in condensed matter theory to reveal the low energy degrees of freedom of a system, or in high energy physics to cure divergence problems. Here we ask which states can be seen as the result of such a renormalization procedure, that is, which states can be “renormalized to high energies”. Intuitively, the continuum limit is the limit of this “renormalization” procedure. We consider two definitions of continuum limit and characterise which states satisfy either one in the context of Matrix Product States. (Joint work with N. Schuch, D. Perez-Garcia and J. I. Cirac.)
