In this brief review, we summarize and elaborate on some of the nomenclature of polaritonic
phenomena and systems as they appear in the literature on quantum materials and …

Recent development of the terahertz time domain spectroscopy (THz-TDS) and its
application to solids have been reviewed. This spectroscopy is unique in that the time …

The quantitative analysis of amino acids by terahertz (THz) time-domain absorption
spectroscopy is demonstrated. The optical densities of the amino acids were found to be …

We identify the bosonic excitations in ferroelectrics that carry electric dipoles from the
phenomenological Landau-Ginzburg-Devonshire theory. The “ferron” quasiparticles emerge …

In this work, we demonstrated a phonon-polariton in the terahertz (THz) frequency range,
generated in a crystallized lead halide perovskite film coated on metamaterials. When the …

Transition metal oxides (TMOs) are among the most contemporary topics in condensed
matter research. For over the past three decades, the most astounding discoveries of high …

We report terahertz time-domain spectroscopy experiments demonstrating strong light–
matter coupling in a terahertz LC metamaterial (MM) in which the phonon resonance of a …

The heating processes of the single-layer gold thin film and the two-layer film assembly of
gold padded with other metal (silver, copper and nickel) irradiated by femtosecond laser …

The measurement of absorption spectra using angle-dependent terahertz (THz) time-
domain spectroscopy for amino acid single crystals of l-cysteine and l-histidine is reported …

A polariton is a fundamental quasiparticle that arises from strong light-matter interaction and
as such has attracted wide scientific and practical interest. When light is strongly coupled to …
