Erich Mueller

About

Erich Mueller is a Professor in the Department of Physics at Cornell University, with a focus on theoretical condensed-matter physics, atomic, molecular, and optical physics, and quantum information. His research centers on the theory of atoms cooled to nanokelvin temperatures, where atoms are described as wave-packets rather than classical billiard balls. He investigates how simple inter-atomic interactions lead to complex collective behavior, aiming to refine the understanding of fundamental physics through atomic systems. Mueller's work often involves designing cold atom experiments to elucidate phenomena from other fields such as solid state physics, nuclear physics, and high energy physics, and he collaborates closely with experimentalists at Cornell and elsewhere. His approach combines analytic and numerical techniques to explore topics like ultracold atomic gases, quantum optics, and exotic quantum phenomena.

• Superfluidity in the one-dimensional Bose-Hubbard model

  Physical review. B./Physical review. B · 2022 · 22 citations

  Senior authorCorresponding

  We study superfluidity in the one-dimensional Bose-Hubbard model using a variational matrix product state technique. We determine the superfluid density as a function of the Hubbard parameters by calculating the energy cost of phase twists in the thermodynamic limit. As the system is critical, correlation functions decay as power laws and the entanglement entropy grows with the bond dimension of our variational state. We relate the resulting scaling laws to the superfluid density. We compare two…

• Unconventional valley-dependent optical selection rules and landau level mixing in bilayer graphene

  Nature Communications · 2020 · 21 citations

  Selection rules are of vital importance in determining the basic optical properties of atoms, molecules and semiconductors. They provide general insights into the symmetry of the system and the nature of relevant electronic states. A two-dimensional electron gas in a magnetic field is a model system where optical transitions between Landau levels (LLs) are described by simple selection rules associated with the LL index N. Here we examine the inter-LL optical transitions of high-quality bilayer…

• High-temperature transport in the one-dimensional mass-imbalanced Fermi-Hubbard model

  Physical review. A/Physical review, A · 2024-06-12 · 5 citations

  articleSenior author

  We study transport in the one-dimensional mass-imbalanced Fermi-Hubbard model in the high-temperature limit, focusing on the case of strong interactions. Prior theoretical and experimental investigations have revealed unconventionally long transport timescales, with complications due to strong finite-size effects. We compute the dynamical current-current correlation function directly in the thermodynamic limit using infinite tensor network techniques. We show that transport in the strong-imbalan…
