Emergent Dirac carriers across a pressure-induced Lifshitz transition in black phosphorus
P. Di Pietro, M. Mitrano, S. Caramazza +11
The phase diagrams of correlated systems like cuprates or pnictides high-temperature superconductors are characterized by a topological change of the Fermi surface under continuous…

High-pressure behavior of methylammonium lead iodide (MAPbI3) hybrid perovskite
Francesco Capitani, Carlo Marini, Simone Caramazza +6
In this paper we provide an accurate high-pressure structural and optical study of MAPbI3 hybrid perovskite. Structural data show the presence of a phase transition towards an orth…

Raman phonon spectrum of the Dzyaloshinskii-Moriya helimagnet Ba2CuGe2O7
F. Capitani, S. Koval, R. Fittipaldi +9
The Raman spectrum of Ba2CuGe2O7, a tetragonal insulator which develops Dzyaloshinsky- Moriya helical magnetism below TN = 3.2 K, has been detected at temperatures varying from 300…
