Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

The theoretical and experimental aspects of the microwave, terahertz, and infrared
properties of superconductors are discussed. Electrodynamics can provide information …

Conventional semiconductor-based digital electronics, with complementary metal oxide
semiconductor (CMOS) technology as the primary example, has experienced meteoric …

The development of the fundamental superconducting (SC) energy scales—the SC energy
gap Δ and the superfluid stiffness J—of granular aluminum, ie, thin films composed of …

Magnetic skyrmions are nanoscale spin configurations that are efficiently created and
manipulated. They hold great promises for next-generation spintronics applications. In …

Quantum bits (qubits) with long coherence times are an important element for the
implementation of medium-and large-scale quantum computers. In the case of …

We investigate how a combination of a nonmagnetic impurity scattering rate γ and finite
subgap states parametrized by Dynes Γ affects various physical quantities relevant to …

In this paper, we report on terahertz frequency-domain spectroscopy (THz-FDS) experiments
in which we measure charge carrier dynamics and excitations of thin-film superconducting …

Quasiparticles represent an intrinsic source of perturbation for superconducting qubits,
leading to both dissipation of the qubit energy and dephasing. Recently, it has been shown …

Investigating solids with light gives direct access to charge dynamics, electronic and
magnetic excitations. For heavy fermions, one has to adjust the frequency of the probing …
