Author(s): C. R. Laumann, R. Moessner, A. Scardicchio, and S. L. Sondhi Motivated by the quantum adiabatic algorithm (QAA), we consider the scaling of the Hamiltonian gap at quantum first-order transitions, generally expected to be exponentially small in the size of the system. However, we show that a quantum antiferromagnetic Ising chain in a staggered field can exhibi... [Phys. Rev. Lett. 109, 030502] Published Thu Jul 19, 2012
