With terahertz and infrared spectroscopy we studied the in-plane response of an underdoped, twinned YBa_{2}Cu_{3}O_{6.6} single crystal with T_{c}=58(1)K in high magnetic fields up to B=30 Tesla (T) applied along the c axis. Our goal was to investiga

Using infrared spectroscopy, the authors study here how the low-energy charge carrier dynamics and band structure of the candidate axion topological insulator EuIn${}_{2}$As${}_{2}$ are affected by its antiferromagnetic transition at ${T}_{\text{N}}$

With infrared spectroscopy, we studied the bulk electronic properties of the topological antiferromagnet $\mathrm{Mn}{\mathrm{Bi}}_{2}{\mathrm{Te}}_{4}$ with ${T}_{N}\ensuremath{\simeq}25\phantom{\rule{4pt}{0ex}}\mathrm{K}$. With the support of band-

We studied the infrared response of polycrystalline samples of the iron arsenide superconductor $(\mathrm{Rb},\mathrm{Cs}){\mathrm{Ca}}_{2}{\mathrm{Fe}}_{4}{\mathrm{As}}_{4}{\mathrm{F}}_{2}$ (Rb,Cs-12442), which has a bilayer structure similar to the

Ultrasonics have been an incisive probe of internal interfaces in a wide variety of systems ranging from stars to solids. For thin-film structures, however, ultrasound is largely ineffective because the signal is dominated by the substrate. Using con

With optical spectroscopy we provide evidence that the insulator-metal transition in ${\mathrm{Sr}}_{2}{\mathrm{Ir}}_{1\ensuremath{-}x}{\mathrm{Rh}}_{x}{\mathrm{O}}_{4}$ occurs close to a crossover from the Mott- to the Slater-type. The Mott gap at $

Significance Elucidating the role of different degrees of freedom in a phase transition is crucial in the comprehension of complex materials. A phase transformation that attracts significant interest is the insulator-to-metal transition of Mott insul

The observation of a charge density wave in the underdoped cuprate high Tc superconductors (Cu-CDW) raised a debate about its relationship with superconductivity. In bulk YBa2Cu3O7−δ the Cu-CDW is incipient and mainly pinned by defects. Neverthele
