    Microscopic origin of ferromagnetism in the trihalides CrCl3 and CrI3

    Abstract:

    Microscopic origin of the ferromagnetic (FM) exchange coupling in two Cr trihalides,
    CrCl3 and CrI3, their common aspects and differences, are investigated on the basis of density functional theory combined with realistic modeling approach for the analysis of interatomic exchange interactions. For these purposes, we perform a comparative study based on the pseudopotential and linear muffin-tin orbital methods by treating the effects of electron exchange and correlation in generalized gradient approximation (GGA) and l ...

    Obstructed Diffusion of a Self-propelled Particle, Simulation Study

    Abstract:

    The great majority of natural active particle systems takes place, in the wild, in
    heterogeneous media: from active transport inside the cell, which occurs in a space that is filled by organelles and vesicles, to bacterial motion, which takes place in heterogeneous environments such as the soil or complex tissues such as in the gastrointestinal tract. Here, diffusion of a self-propelled particle in the presence of randomly distributed obstacles is presented using simulation results. It is found that depending on the magnitu ...

    Probing the Higgs CP Nature in the $Htotau^+tau^-$ Decay

    PARTICLES AND ACCELERATORS

    Abstract: : There are many theoretical models which predict the existence of a pseudoscalar Higgs. As the Standard Model Higgs is predicted to be a scalar, measuring the Higgs CP is highly motivated as it is a clear sign of physics beyond the Standard Model. One way to probe the Higgs CP is through its decay to two taus. In this talk, we review two main methods for this measurement, using data from the CMS experiment. Using a multi-variant analysis to identify the correct tau decay channels, we show that the CP sensitivity improves by 22$%$ when using the $rho$-decay plane method in the $rho-rho$ and $rho-a_1$ decay channels with the 2016 da ...

    Contamination is graphene's kryptonite

    Abstract:

    Large-scale, cost-effective methods for producing high-quality and functional atomically thin two-dimensional (2D) materials with unmatched properties are critical to realizing commercial applications of these promising materials. However, the current top-down synthesis methods are prone to contamination, which can adversely affect properties, such as optical absorption and emission, electrochemical properties, carrier mobility, biological activity and toxicological properties. These contaminants can cause inferior or unpredictable properties and are at the h ...
