In this article, we provide a comprehensive review of past and present efforts in the field of
microwave nonreciprocity with an emphasis on the most commonly used nonreciprocal …

Encoding quantum information into a set of harmonic oscillators is considered a hardware
efficient approach to mitigate noise for reliable quantum information processing. Various …

We present a circuit design composed of two Josephson junctions coupled by a
nonreciprocal element, the gyrator, whose ground space is doubly degenerate. The ground …

Unique properties of plasmons in two-dimensional electron systems (2DESs) have been
studied for many years. Existing theoretical approaches allow for analytical study of the …

A well-known component of RF systems is the circulator, a three-port device that allows
signals to flow in one direction while inhibiting propagation in the reverse direction …

Hydrodynamic and viscous effects in electronic liquids are at the focus of much current
research. Most intriguing is perhaps the nondissipative Hall viscosity, which, due to its …

We present a model study of an alternative implementation of a two-port Hall-effect
microwave gyrator. Our setup involves three electrodes, one of which acts as a common …

Coulomb interaction has important consequences for the physics of quantum spin Hall edge
states, weakening the topological protection via two-particle scattering and renormalizing …

We predict a plasmonic excitation that exhibits chiral properties in the absence of external
magnetic field. This excitation, that we call an interedge chiral Berry plasmon (IE CBP), is …

Quantum Hall edge states have some characteristic features that can prove useful to
measure and control solid state qubits. For example, their high voltage to current ratio and …
