Impact of terahertz short pulses on the oxygen defect state in TiO
Paola Di Pietro, Johannes Schmidt, Nidhi Adhlakha +7
Oxygen deficient titanium dioxide (TiO) is a very attractive material for several applications ranging from photocatalysis to resistive switching. Oxygen vacancies turn ins…
Terahertz Saturable Absorption from Relativistic High-Temperature Thermodynamics in Black Phosphorus
Nidhi Adhlakha, Zeinab Ebrahimpour, Paola Di Pietro +7
Thanks to its tunable infrared band-gap and to its anisotropic conduction properties, black phosphorus represents a very unique 2D material, whose potential in the engineering of n…
Non-adiabatic suppression of 3D excitonic screening in black phosphorus by mid-infrared pulses
Angela Montanaro, Francesca Giusti, Matteo Zanfrognini +10
The competition between the electron-hole Coulomb attraction and the three-dimensional dielectric screening dictates the optical properties of layered semiconductors. In low-dimens…
Pressure tuning of light-induced superconductivity in K3C60
A. Cantaluppi, M. Buzzi, G. Jotzu +7
Optical excitation at terahertz frequencies has emerged as an effective means to manipulate complex solids dynamically. In the molecular solid K3C60, coherent excitation of intramo…
Interband characterization and electronic transport control of nanoscaled GeTe/SbTe superlattices
Antonio Caretta, Barbara Casarin, Paola Di Pietro +8
The extraordinary electronic and optical properties of the crystal-to-amorphous transition in phase-change materials led to important developments in memory applications. A promisi…
Electronic correlation assisted ferroelectric metallic state in LiOsO
I. Lo Vecchio, G. Giovannetti, M. Autore +6
LiOsO has been recently identified as the first unambiguous "ferroelectric metal", experimentally realizing a prediction from 1965 by Anderson and Blount. In this work, we inve…
An optically stimulated superconducting-like phase in K3C60 far above equilibrium Tc
M. Mitrano, A. Cantaluppi, D. Nicoletti +10
The control of non-equilibrium phenomena in complex solids is an important research frontier, encompassing new effects like light induced superconductivity. Here, we show that cohe…
Electrodynamics of superconducting pnictide superlattices
A. Perucchi, F. Capitani, P. Di Pietro +8
It has been recently reported (S. Lee et al., Nature Materials 12, 392, 2013) that superlattices where layers of the 8% Co-doped BaFe2As2 superconducting pnictide are intercalated…
Reproduction of Experimental Gap Structure in LiFeAs based on the Orbital-Spin Fluctuation Theory: -wave, -wave, and hole--wave states
Tetsuro Saito, Seiichiro Onari, Youichi Yamakawa +3
The absence of nesting between electron and hole-pockets in LiFeAs with K attracts great attention, as an important hint to understand the pairing mechanism of Fe-based s…
Phase diagram and optical conductivity of La1.8-xEu0.2SrxCuO4
M. Autore, P. Di Pietro, P. Calvani +5
La1.8-xEu0.2SrxCuO4 (LESCO) is the member of the 214 family which exhibits the largest intervals among the structural, charge ordering (CO), magnetic, and superconducting transitio…
Infrared evidence of a Slater metal-insulator transition in NaOsO3
Irene Lo Vecchio, Andrea Perucchi, Paola Di Pietro +6
The magnetically driven metal-insulator transition (MIT) was predicted by Slater in the fifties. Here a long-range antiferromagnetic (AF) order can open up a gap at the Brillouin e…
Optical conductivity of Bismuth-based topological insulator
P. Di Pietro, F. M. Vitucci, D. Nicoletti +6
The optical conductivity and the spectral weight of four topological insulators with increasing chemical compensation (Bi2Se3, Bi2-xCaxSe3, Bi2Se2Te, Bi2Te2Se) have been measured f…
An extended infrared study of the (p,T) phase diagram of the p-doped Cu-O plane
D. Nicoletti, P. Di Pietro, O. Limaj +5
The ab-plane optical conductivity of eleven single crystals, belonging to the families Sr2-xCuO2Cl2, Y1-xCaxBa2Cu3O6, Bi2Sr2-xLaxCuO6, and Bi2Sr2CaCu2O8 has been measured with hole…
