• Abstract: We investigate electron paring in two-dimensional electron systems mediated by the vacuum fluctuations of a quantized magnetic flux generated by the inductor of an LC resonator. The interaction induces long-range attractive interactions between angular momentum states which lead to pairing in a broad class of materials with critical temperatures of few Kelvin or even higher, depending on the field-covered area. The induced state is a pair-density wave topological chiral superconductor. The proposed platform in circuit QED environment offers a tunable promising tool for engineering electron interactions in two-dimensional systems to create new quantum phases of matter.

• Longitudinal (curvature) couplings of an $N$-level qudit to a superconducting resonator at the adiabatic limit and beyond [0.0]
  We investigate the coupling between a multi-level system, or qudit, and a superconducting (SC) resonator's electromagnetic field. For the first time, we derive Hamiltonians describing the longitudinal multi-level interactions in a general dispersive regime. We provide examples illustrating the transition from adiabatic to dispersive coupling in different qubit systems.

• Coulomb interaction-driven entanglement of electrons on helium [0.0]
  We theoretically investigate the generation of emphmotional entanglement between two electrons via their unscreened Coulomb interaction. We compute the motional energy spectra of the electrons, as well as their entanglement, by diagonalizing the model Hamiltonian with respect to a single-particle Hartree product basis. In particular, the theoretical tools developed here can be used for fine tuning and optimization of control parameters in future experiments with electrons trapped above the surface of superfluid helium or solid neon.

  The effect of the quantized electromagnetic field in the displacement current of a resonant tunneling diode is analyzed. This mimics known effects predicted by a Jaynes-Cummings model in closed systems. The computational burden involved in the multi-time measurements of THz currents is tackled by invoking a Bohmian description of the light-matter interaction.

  We propose a novel quantum electrodynamics (QED) platform where quantum emitters interact with a Hofstadter-ladder waveguide. By assuming emitter's frequency to be resonant with the lower band, we find that the spontaneous emission is chiral. Due to quantum interference, we find that both the emitter-waveguide interaction and the amplitudes of bound states are periodically modulated by giant emitter's size.

  Quantum mechanical effects at the macroscopic level were first explored in Josephson junction-based superconducting circuits in the 1980s. In the last twenty years, the emergence of quantum information science has intensified research toward using these circuits as qubits in quantum information processors.
