- Abstract: Transmission lines are excellent examples of quantum simulators of quantum fields. By appropriately driving specific circuit elements, these devices can reproduce relativistic and quantum such as particle creation due to the non-adiabatic stimulation of the quantum vacuum. We investigate particle creation in left-handed transmission lines induced by the modulation of the Josephson energy in superconducting quantum interference devices. Our results show that, as a consequence of the peculiar dispersion relations present in these systems, particle production occurs with much more favorable conditions with respect to the usual right-handed transmission lines.

We show that, by activating specific resonance conditions, this platform can be used as a quantum simulator of different phenomena in quantum optics, multimode quantum systems and quantum thermodynamics.

Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems.
We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons.
We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

Nonreciprocal effects in nanoelectronic devices offer unique possibilities for manipulating electron transport and engineering quantum electronic circuits.
We provide a general input-output description of nonreciprocal transport in solid-state quantum dot architectures.
We show that a nonreciprocal coupling induces unidirectional electron flow in the resonant transport regime.
