Quantum simulation of the tricritical Ising model in tunable Josephson junction ladders — •Niklas Tausendpfund1,2, Lorenzo Maffi3, Matteo Rizzi1,2, and Michele Burrello31Peter Grünberg Institut 8, Forschungszentrum Jülich, Jülich, Germany — 2Institute for Theoretical Physics, University of Cologne, Köln, Germany — 3Niels Bohr Institute, University of Copenhagen, Copenhagen, Denmark

Modern hybrid superconductor-semiconductor Josephson junction arrays are a promising platform for analog quantum simulations. Their controllable and non-sinusoidal energy/phase relationship opens the way to implement non-trivial interactions and to study the emergence of exotic quantum phase transitions. Here we present the analysis of a 2-leg ladder geometry composed of Josephson junctions. Our results support the existence of tricritical Ising phase transitions based on bosonization and matrix product state techniques. This proposal provides a useful one-dimensional building block for designing exotic topological orders in two-dimensional scalable Josephson junction arrays.
