	Scattering amplitudes are the cornerstones of our current understanding of quantum field theories. On-shell methods offer efficient ways to calculate amplitudes in some theories and uncover beautiful structures usually obscured by the Feynman diagrammatics. The planar maximal supersymmetric (N=4) gauge theory is well suited for the use of on-shell methods, and the amplitudes have a positive geometry description in terms of the amplituhedron. We discuss the spontaneously symmetry broken N=4 super Yang-Mills theory and pure gauge theory in this talk. We study the so-called `on-shell functions' in the massive N=4 SYM, and realize the massive BCFW shifts as on-shell diagrams. We stumble upon mass deforming BCFW shifts. We discuss the maximal cut of simple loop diagrams and, using the generalized unitarity, find the loop amplitudes in massive N=4 SYM. In the second part of the talk, we discuss the pure gauge theory and realize its amplitudes from the positive geometry and combinatorics. The associahedron is a combinatorial object capturing the combinatorics of triangulations of an n-gon, and hence planar trivalent graphs. We make use of the Corolla polynomials to spin up the canonical form of the associahedron, yielding the gluon amplitudes. The similar Corolla polynomials for one loop lead us to the loop integrand of the n-gluon scattering. We use another representation of the Corolla polynomial to spin up the recently discovered curve integral formula.


	Glassy dynamics in polymeric systems remain an area of intense interest, particularly in topologically constrained ring polymers, which exhibit unique relaxation mechanisms due to the absence of free ends and the presence of topological interactions. In this talk, I will present results from large-scale molecular dynamics simulations investigating the aging behavior of dense ring polymer systems with varying backbone stiffness. We identify the glass transition temperature (Tg) as a function of polymer stiffness and demonstrate that increasing stiffness enhances configurational constraints, leading to a higher Tg. Analysis of intermediate scattering function reveals that the relaxation time grows sublinearly with waiting time, highlighting the slow relaxation dynamics characteristic of these systems. A key feature of our system is the presence of threading interactions, which become increasingly persistent as the system ages. Our findings provide a comprehensive picture of aging in glassy ring polymer systems, demonstrating how topological constraints and polymer stiffness govern slow relaxation and non-equilibrium behavior.
