Strain as a tool to stabilize the isotropic triangular lattice in a geometrically frustrated organic quantum magnet
Francisco Lieberich, Yohei Saito, Yassine Agarmani +5
Geometric frustration is a key ingredient in the emergence of exotic states of matter, such as the quantum spin liquid in Mott insulators. While there has been intense interest in…

Slow and Non-Equilibrium Dynamics due to Electronic Ferroelectricity in a Strongly-Correlated Molecular Conductor
Tatjana Thomas, Yassine Agarmani, Steffi Hartmann +7
Using a combination of resistance fluctuation (noise) and dielectric spectroscopy we investigate the nature of relaxor-type electronic ferroelectricity in the organic conductor …

Ultrafast gap dynamics upon photodoping the Mott-insulating phase of a two-dimensional organic charge-transfer salt
Konstantin Warawa, Yassine Agarmani, Harald Schubert +4
We investigate experimentally the ultrafast changes in the spectral response of the Mott insulator -(BEDT-TTF)Cu[N(CN)]Cl (-Cl) upon photodoping with intense excitati…
