Membrane Based Materials
Biological membranes are exceptional materials that combine seemingly divergent properties. They are mechanically tough and difficult to rupture, yet they are highly fluid and readily change shape. They are permeable to certain molecules while impermeable to others. These attributes also make membranes attractive from a materials perspective. A materials scientist and a biological cell face similar challenges when using membranes to build materials or organelles. How can laterally heterogeneous compartmentalized membranes be designed? How can 3D membrane shape be dynamically manipulated? How can transport across membranes be regulated? Wewill describe Brandeis MRSEC results, and our future plans to elucidate design principles that govern these structures and processes. Our ultimate goals are to engineer membrane-based materials and to illuminate how biological cells use membrane-based structures to achieve specific functions. We are pursuing these goals using two complementary systems (1) conventional lipid bilayers deformed by interacting nanoparticles and proteins and (2) colloidal monolayers, which are 2D one-rod-length thick liquid membranes comprised of aligned rod-like colloids.

Topological modes bound to lattice dislocations in mechanical metamaterials
The mechanical rigidity of frameworks -- nodes connected by springs or rigid bars -- underlies the structural integrity of bridges, the response of granular materials, and the design of metamaterials with unusual mechanical properties. A fundamental question governing rigidity is the existence of soft modes: motions that do not significantly stretch or compress the constituent elements of the structure. We demonstrate a novel way to introduce soft modes at desired locations in a metamaterial, by exploiting the properties of a recently introduced class of topological metamaterials. These are special periodic frameworks which exhibit localized edge modes, analogous to the electronic edge states of topological insulators. We show that dislocations in such metamaterials are associated with soft modes of topological origin. The existence of the modes is determined by the interplay between two Berry phases -- the Burgers vector of the dislocation and a topological "polarization" characterizing the underlying lattice. Simple prototypes built out of triangular plates joined by hinges provide a visual demonstration of these modes.

Randomness in number theory and geometry
Abstract:

Abstract : The behavior of many arithmetic and geometric objects ,from the zeros of zeta functions

to the the topologies of random real algebraic varieties are apparently dictated by models

from statistical physics. We will review some of these and highlight the basic conjectures

and some of what is known towards them.

Nodal domains for Maass (modular) forms
Abstract : The eigenstates of the quantization of a classically chaotic hamiltonian are expected to

behave like random monochromatic waves .We discuss this in the context of the eigenfunctions

on the modular surface-ie "Maass Forms ", and especially what can be proved about their nodal

domains.

Equidistribution of expanding translates of curves in homogeneous spaces and its application to Diophantine approximation
We consider an analytic curve $\varphi: I \rightarrow \mathbb{M}(n\times m, \mathbb{R}) \hookrightarrow \mathrm{SL}(n+m, \mathbb{R})$, embed it into some homogeneous space $G/\Gamma$, and translate it via some diagonal flow $\{a(t): t > 0 \} < \mathrm{SL}(n+m,\mathbb{R})$. Under some geometric conditions on $\varphi$, we prove the equidistribution of the evolution of the translated curves $a(t)\varphi(I)$ in $G/\Gamma$, and as a result, we prove that for almost all points on the curve, the Dirichlet's theorem can not be improved. This is a joint work with Nimish Shah.
