    Pseudochaotic many-body dynamics as a pseudorandom state generator

    Pseudochaotic dynamics

    We define pseudochaotic dynamics as a non-chaotic unitary time evolution with i. computational indistinguishability from chaotic time evolution via OTOCs, and ii. capability to generate pseudorandom states. The latter…

  • A DFT study of the effect of strain on the structural and electronic properties of perovskite APbBr3 (A = K, Rb, and Cs)

    A DFT study of the effect of strain on the structural and electronic properties of perovskite APbBr3 (A = K, Rb, and Cs)

    The literature15,22 reports the tetragonal phase of perovskite CsPbBr3 crystal. This perovskite has the experimental lattice constant a = 6.0173 Å and belongs to the P4mm space group. The covalent bonds in perovskite CsPbBr3 formed by…
