Successes and challenges of using Semidefinite Programming for the study of Spin Chain Hamiltonians
David Berenstein, P. N. Thomas Lloyd
We study semidefinite programming (SDP) methods to analyze spin chain Hamiltonians. We examine the ground state energy, the first excited charged states and ground state correlator…
Numerical exploration of the bootstrap in spin chain models
David Berenstein, George Hulsey, P. N. Thomas Lloyd
We analyze the bootstrap approach (a dual optimization method to the variational approach) to one-dimensional spin chains, leveraging semidefinite programming to extract numerical…
Staggered bosons and Kahler-Dirac bosons
David Berenstein, Simon Catterall, P. N. Thomas Lloyd
We describe a novel way to think about bosonic lattice theories in Hamiltonian form where each lattice site has only a half boson degree of freedom. The construction requires a non…
