Using strain to uncover the interplay between two- and three-dimensional charge density waves in high-temperature superconducting YBa $_{2}$ Cu $_{3}$ O $_{y}$

Igor Vinograd, Sofia Michaela Souliou, Amir-Abbas Haghighirad +14

Uniaxial pressure provides an efficient approach to control the competition between charge density waves (CDWs) and superconductivity in underdoped YBa $_{2}$ Cu $_{3}$ O $_{y}$ . I…

The high-pressure phase diagram of BaNi $_{2}$ As $_{2}$ : unconventional charge-density-waves and structural phase transitions

Tom Lacmann, Amir-Abbas Haghighirad, Sofia-Michaela Souliou +5

Structural phase transitions accompanied by incommensurate and commensurate charge density wave (CDW) modulations of unconventional nature have been reported in BaNi $_{2}$ As $_{2}$ , a n…

Disentangling lattice and electronic instabilities in the excitonic insulator candidate Ta $_{2}$ NiSe $_{5}$ by nonequilibrium spectroscopy

Kota Katsumi, Alexandr Alekhin, Sofia-Michaela Souliou +7

Ta $_{2}$ NiSe $_{5}$ is an excitonic insulator candidate showing the semiconductor/semimetal-to-insulator (SI) transition below $T_{c}$ = 326 K. However, since a structural transi…

Strong electron-phonon coupling and enhanced phonon Grüneisen parameters in valence-fluctuating metal EuPd $_{2}$ Si $_{2}$

Mai Ye, Mark Joachim Graf von Westarp, Sofia-Michaela Souliou +7

We study the valence crossover and strong electron-phonon coupling of EuPd $_{2}$ Si $_{2}$ by polarization-resolved Raman spectroscopy. The fully-symmetric phonon mode shows strongly asy…

Elastoresistivity in the incommensurate charge density wave phase of BaNi $_{2}$ (As $_{1-x}$ P $_{x}$ ) $_{2}$

M. Frachet, P. W. Wiecki, T. Lacmann +7

Electronic nematicity, the breaking of the crystal lattice rotational symmetry by the electronic fluid, is a fascinating quantum state of matter. Recently, BaNi $_{2}$ As $_{2}$ has emerg…
