Metallic nanoparticles of Au, Pt and Pt/Au have been synthesized using a chemical reduction approach. The structural characterization of these metallic nanoparticles has been carried out using conventional transmission electron microscopy (TEM) and high resolution transmission electron microscopy (HR-TEM) techniques. HR-TEM images of Pt nanoparticles reveal their fcc-like structures, in the [10...

Previously reported at a temperature of 298 (2) K [Lee & Joo (2007 ▶). Acta Cryst. E63, i11-i13], the title compound, K(7)[H(9)α-Pt(2)Mo(12)O(48)]·11H(2)O or K(7)[H(4.5)α-PtMo(6)O(24)](2)·11H(2)O, was redetermined at 146 (2) K in order to determine whether the H atom in the hydrogen bond that crosses the center of symmetry was located at the center of symmetry or disordered around it as assumed...

Abstract With consideration of parity-time (PT) symmetry, Lorentz reciprocity theorem, and real Bloch phase, we propose a generalized parametric space for any PT-symmetric unit cells that can comprehensively illustrate the PT phase transition, necessary conditions exotic wave scattering in general finite periodic photonic structures. We put forward rigorous formal expressions bi-directional ref...

Exceptional degeneracies, at which both eigenvalues and eigenvectors coalesce, parity-time ($\mathcal{PT}$) symmetry, reflecting balanced gain loss in photonic systems, are paramount concepts non-Hermitian systems. We here complete the topological classification of exceptional nodal degeneracies protected by $\mathcal{PT}$ symmetry up to three dimensions provide simple example models whose topo...

In this work we first propose a method for the derivation of general continuous antilinear time-dependent (TD) symmetry operator I(t) I(t) TD non-Hermitian Hamiltonian H(t) disp...

We discover novel transitions characterized by distinguishability of bosons in non-unitary dynamics with parity-time ($\mathcal{PT}$) symmetry. show that $\mathcal{PT}$ symmetry breaking, a unique transition non-Hermitian open systems, enhances regions which can be regarded as distinguishable. This means classical computers sample the boson distributions efficiently these sampling distribution ...

Abstract PT-symmetric quantum theory was originally proposed with the aim of extending standard by relaxing Hermiticity constraint on Hamiltonians. However, no such extension has been formulated that consistently describes states, transformations, measurements and composition, which is a requirement for any physical theory. We to answer question whether consistent observables extends this withi...
