• Abstract: We introduce a tunable synthetic-dimension platform for realizing Kitaev-chain physics with high degree of control over Majorana zero modes. It is based on a generic Landau-quantized two dimensional electron system coupled to the magnetic flux of a superconducting LC circuit. The structured vector potential of a superconducting LC inductor induces attractive interactions between electron angular-momentum states at the lowest Landau level. These states serve as a synthetic dimension for the coveted fermionic Kitaev chain, with Majorana zero modes existing at the boundaries of the angular-momentum lattice. The crucial advantage of this proposal is the possibility of a robust, nonlocal readout and control of the Majorana states by a LC resonator. The platform relies on mature circuit QED and semiconductor technologies and provides a promising pathway to topological quantum computing.

  We propose a one-dimensional electronic nanodevice inspired in recently fabricated semiconductor-superconductor-ferromagnetic insulator hybrids. We show that the device can be tuned across spin- and fermion parity-changing QPTs by adjusting the FMI layer length orange and/or by applying a global backgate voltage. Our findings suggest that these effects are experimentally accessible and offer a robust platform for studying quantum phase transitions in hybrid nanowires.

  We show that it is possible to avoid some of the main experimental hurdles by using only local proximity effect on each quantum dot. There is no need for narrow superconducting couplers, additional Andreev bound states, or spatially varying magnetic fields. We use a realistic spinful, interacting model and show that high-quality Majorana bound states can be generated already in a double quantum dot.

  Kondo effect is a genuine manifestation of the nonlocality of Majorana modes. We simulate the relaxation of the Majorana magnetization, which allows us to determine the related Kondo temperature.
