For decades, the terahertz (THz) frequency band had been primarily explored in the context
of radar, imaging, and spectroscopy, where multi-gigahertz (GHz) and even THz-wide …

We present an extensive study of resonant two-dimensional (2D) plasmon excitations in
grating-gated quantum well heterostructures, which enable an electrical control of periodic …

Ever increasing demands of data traffic makes the transition to 6G communications in the
300 GHz band inevitable. Short-channel field-effect transistors (FETs) have demonstrated …

Graphene plasmonics has recently attracted remarkable attention, with reports of numerous
intriguing properties and novel device demonstrations. As a two-dimensional (2-D) …

We theoretically demonstrate that a system formed by two coupled graphene sheets enables
a negative damping regime wherein graphene plasmons are pumped by a direct current …

We present a comprehensive theory of the Dyakonov-Shur (DS) plasma instability in current-
biased graphene transistors. Using the hydrodynamic approach, we derive equations …

An electron electric dipole moment (eEDM) search using laser-coolable triatomics such as
YbOH is one of the most sensitive probes for physics beyond the standard model. The eEDM …

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 …

The terahertz (THz) technology has found applications ranging from astronomical science
and earth observation to compact radars, non-destructive testing, chemical analysis …

Triatomic molecule RaOH combines the advantages of laser coolability and the spectrum
with close opposite-parity doublets. This makes it a promising candidate for experimental …
