  • Can a nn Resonance Constrain the n Amplitude?

    Afnan, Iraj R.   Gibson, Benjamin F.  

    We address the question of constraints on the n amplitude as a result of observing a nn resonance above the nn three-body threshold. To examine this question, we will first demonstrate that by starting with a n interaction based upon the experimental p data and then scaling the n potential by approximate to 8% one can generate a nn resonance, and with a sufficiently large scaling one can generate a nn bound state. This is achieved using the three-body Faddeev equations with rank one separable potentials for all pairwise interactions. The use of separable potentials is motivated by two factors: (i) the Faddeev equations reduce to a set of one dimensional integral equations that can be analytically continued into the complex energy plane where resonances reside. (ii) The n amplitude can be defined in terms of the effective range parameters. As a result we can explore the question: What constraint can be placed on the n effective range parameters by the nn resonance parameters?

  • A first-principles study of NinPdn (n=3D1-5) clusters

    Cervantes-Flores, Aldo   Cruz-Martinez, Heriberto   Solorza-Feria, Omar   Calaminici, Patrizia  

    A first-principle investigation of structures and properties of NinPdn (n =3D 1-5) clusters is presented. For this study, the linear combination of Gaussian-type orbitals auxiliary density functional theory (LCGTO-ADFT) method has been employed. In order to determine the lowest energy structures, several isomers in different spin multiplicities were studied, for each cluster size. Initial structures, for which successive geometry optimization was computed without any constrain, were taken along Born-Oppenheimer molecular dynamics (BOMD) trajectories. To discriminate between minima and transition state structures, harmonic frequency analyses were performed at the optimized structures. Ground state structures, bond lengths, harmonic frequencies, dissociation energy, ionization potential, electron affinity and spin density plots are presented. This work demonstrates, that the Pd atoms prefer to allocate on the surface of the cluster structures whose core is formed by the 3d TM atoms type. Moreover, it has been observed that the ground-state structure spin multiplicity increases as the system size grows. The results of this study contribute to gain insight into how structures and energy properties change with cluster size in bimetallic Pd-based alloys.

  • A disk-type polyarene containing four B <- N units

    Min, Yang   Dou, Chuandong   Tian, Hongkun   Liu, Jun   Wang, Lixiang  

    In this manuscript, we report a disk-type polyarene consisting of an all-hexagon -framework and four BN units. It exhibits intriguing electronic structures and opto-electronic properties, such as locally modulated (anti)aromaticity, strong red fluorescence and n-type semiconductor characteristics, thus representing a new kind of pi-molecule containing B <- N units.

  • Mass-deformed T N as a linear quiver

    Hayashi, Hirotaka   Tachikawa, Yuji   Yonekura, Kazuya  

    The T-N theory is a non-Lagrangian theory with SU(N)(3) flavor symmetry. We argue that when mass terms are given so that two of SU(N)'s are both broken to SU(N-1) xU(1), it becomes TN-1 theory coupled to an SU(N-1) vector multiplet together with N fundamentals. This implies that when two of SU(N)' s are both broken to U(1) (N-1), the theory becomes a linear quiver. We perform various checks of this statement, by using the 5d partition function, the structure of the coupling constants, the Higgs branch, and the Seiberg-Witten curve. We also study the case with more general punctures.
