Quantum Monte Carlo Simulation of the 3D Ising Transition on the Fuzzy Sphere
Johannes S. Hofmann, Florian Goth, Wei Zhu +2
We present a numerical quantum Monte Carlo (QMC) method for simulating the 3D phase transition on the recently proposed fuzzy sphere [Phys. Rev. X 13, 021009 (2023)]. By introducin…
Anomalously long lifetimes in two-dimensional Fermi liquids
Johannes Hofmann, Ulf Gran
A precise characterization of the recently discovered crossover to hydrodynamic transport in electron liquids, and in particular of a conjectured exotic odd-parity transport regime…
Uncovering conformal symmetry in the Ising transition: State-operator correspondence from a fuzzy sphere regularization
Wei Zhu, Chao Han, Emilie Huffman +2
The Ising transition, the most celebrated and unsolved critical phenomenon in nature, has long been conjectured to have emergent conformal symmetry, similar to the case of the…
Scale Invariance in the Lowest Landau Level
Johannes Hofmann, Wilhelm Zwerger
We show that the discrete set of pair amplitudes introduced by Haldane are an angular-momentum resolved generalization of the Tan two-body contact, which parametrizes univers…
Collective modes in interacting two-dimensional tomographic Fermi liquids
Johannes Hofmann, Sankar Das Sarma
We develop an analytically solvable model for interacting two-dimensional Fermi liquids with separate collisional relaxation rates for parity-odd and parity-even Fermi surface defo…
Few-to-many-particle crossover of pair excitations in a superfluid
Fabian Resare, Johannes Hofmann
Motivated by recent advances in the creation of few-body atomic Fermi gases with attractive interactions, we study theoretically the few-to-many-particle crossover of pair excitati…
