Query: Density-Matrix Renormalization Group for Continuous Quantum Systems   We introduce a versatile and practical framework for applying matrix product
state techniques to continuous quantum systems. We divide space into multiple
segments and generate continuous basis functions for the many-body state in
each segment. By combining this mapping with existing numerical Density-Matrix
Renormalization Group routines, we show how one can accurately obtain the
ground-state wave function, spatial correlations, and spatial entanglement
entropy directly in the continuum. For a prototypical mesoscopic system of
strongly-interacting bosons we demonstrate faster convergence than standard
grid-based discretization. We illustrate the power of our approach by studying
a superfluid-insulator transition in an external potential. We outline how one
can directly apply or generalize this technique to a wide variety of
experimentally relevant problems across condensed matter physics and quantum
field theory.
