Systematic interpolatory ansatz for one-dimensional polaron systems
E. J. Lindgren, R. E. Barfknecht, N. T. Zinner
We explore a new variational principle for studying one-dimensional quantum systems in a trapping potential. We focus on the Fermi polaron problem, where a single distinguishable i…

State transfer in an inhomogeneous spin chain
Michael Iversen, Rafael Emilio Barfknecht, Angela Foerster +1
We present an analytical study of state transfer in a spin chain in the presence of an inhomogeneous set of exchange coefficients. We initially consider the homogeneous case and de…
