      abstract     = {We investigate the ground state properties of
                      one-dimensional hard-core bosons interacting via a variable
                      long-range potential using the density matrix
                      renormalization group. We show that restoring energy
                      extensivity in the system, which is done by rescaling the
                      interaction potential with a suitable size-dependent factor
                      known as Kac's prescription, has a profound influence on the
                      low-energy properties in the thermodynamic limit. While an
                      insulating phase is found in the absence of Kac's rescaling,
                      the latter leads to a new metallic phase that does not fall
                      into the conventional Luttinger liquid paradigm. We discuss
                      a scheme for the observation of this new phase using
                      cavity-mediated long-range interactions with cold atoms. Our
                      findings raise fundamental questions on how to study the
                      thermodynamics of long-range interacting quantum systems.},
