Towards the Onset of Collectiveness in Smart Nano Materials: Ferroics and Superconductors

Massachusetts Institute of TechnologyOrganizer Department of Molecular Chemistry and Materials ScienceContact Details Show full text description of Understanding and controlling functional materials at the na...» Understanding and controlling functional materials at the nanoscale is a major goal of materials science, chemistry and physics, allowing the field to continuously pioneer also the high-tech industry. Nano-functional systems, such as ferroic and superconducting materials form an elegant platform for studying the onset of collective interactions in nature in general and chemistry in particular. Likewise, the ‘collectiveness’ of these materials facilitates them for technologies, including low-power computers, mainstream cellular antennae, single photon detectors and quantum computers. Nevertheless, to-date, the onset of collectiveness in these smart nano materials has remained elusive to us, mainly due to challenges associated with controlling and imaging the collective properties near the onset of the phenomena.
We will discuss a recently-found universal scaling law that describes superconductivity close to its emergence, allowing us to learn how material properties dictate size effects in superconductivity. I will also demonstrate how the discovered universality helps improve material preparation with controlled functionality, affecting both the fundamental study of superconductivity, e.g. by enabling graphene-superconductor and amorphous-crystalline hybrids in the ultrathin regime (< 20 nm). The significance to miniaturised superconducting-based devices will also be presented. Using the improved functionality, we will examine how the competition between material properties and intrinsic superconducting properties can be tuned with the control on the materials structure.
I will also demonstrate how the longstanding dispute over the ferroelectric domain switching mechanism can be resolved when introducing recently-discovered ferroelectric-ferroelastic domain types. We will also examine by means of direct observation ferroelectric domain pinning due to structural defects. These observations were allowed thanks to a new method that allows an order of magnitude enhancement of ferroelectric domain imaging, with respect to the traditional methods.

The superluminous supernovae have luminosities 100 times greater than a core-collapse supernova, and their origin is a mystery. I will present data on two of the most distant and best-observed events from the Supernova Legacy Survey, and the first radiative transfer model that gives insight into their origin. They seem to result from the creation and spin-down of a magnetar. I'll also discuss a range of both normal and exotic supernovae from the local universe, including an even newer class of superluminous supernovae, and show how new observations are revealing or limiting SN progenitors for the first time. The Las Cumbres Observatory Global Telescope Network (LCOGT) is one of the latest tools allowing new kinds of observations with its 11 node network of one and two meter robotic telescopes spanning the globe. We have now begun the LCOGTSupernova Key Project, which will collect the largest sample of low-redshift supernovae ever obtained: lightcurves and spectroscopy on 450 supernovae over 3 years for use in cosmology, understanding explosions, and determining supernova progenitors. -

We assume that the spacecraft that orbits the Earth is tracked using the observed tick rate of its clock, which is then compared to the tick rate of a local clock on the ground. The spacecraft's reconstructed 4-D trajectory can reveal the nature of gravitational perturbations in the gravitational field of the Earth testing multiple relativistic effects such as frame dragging and shapiro time delay, and potentially differentiating between different theories of gravity via Parametrized Post-Newtonian Parameters (PPN). On the ground, clocks along with the most recent optical fiber technology measure ground uplift at a precision that competes with existent technology (e.g, GPS, gravimeters). This monitoring has a plethora of applications, which include closer monitoring of the solid Earth tide in areas where hydraulic fracturing is performed, and potentially better monitoring of areas with high seismic and volcanic activity.

Statistical Physics SeminarContact Abstract Show full text abstract about A sheet of paper that has been crumpled and flattened retain...» A sheet of paper that has been crumpled and flattened retains some amount of shapability that a bare, uncrumpled, sheet does not have: when deformed by external forces, it retains the deformed shape after the forces are removed. Using a frustrated two dimensional lattice of springs, we show that such shapability can be attained in a non-dissipative system. Numerical investigations suggest an extensive number of bistable energy minima using several variants of this scheme. The numerical sheet can be bent into a nearly-closed cylinder that holds its shape. We verify that the deformed shape is locally stable and compare its bending modulus in the deformed state with that in the initial flat state. We investigate the threshold for non-elastic deformation using various kinds of forcing. -

the intraseasonal time scale (say, 20-90 day periods) and one of the most important
coherent, quasi-periodic modes of natural variability in the global climate system altogether.
Though it was discovered over 40 years ago, we still do not understand the MJO, in the sense of
being able to state an agreed-upon, simple mathematical model that explains its basic features.
I will present evidence that the MJO is what some of us now call a "moisture mode", best
analyzed by examining the budget of moist static energy or moist entropy. I will argue that
cloud-radiative feedbacks are important to the maintenance of the MJO, while horizontal
advection of moisture is important to its eastward propagation. I will present evidence from
observations, theory, general circulation models, and cloud-resolving models to this effect.

Sandwiches at 12:45Abstract Show full text abstract about Evolution acts on individual variation. Complex biological s...» Evolution acts on individual variation. Complex biological systems, such as colonies of social insects, are aggregates of multiple agents working together towards collective, higher-order goals, producing emergent collective properties on which natural selection acts. There is no central control dictating the activities of members in the assembly. Instead, agents use local signals that determine their behavior and are received through an intricate interaction network resulting in collective phenotypes. I examine how individual variation among workers in harvester ant colonies affects the collective behavior of the colony, producing individual variation among colonies. I will present work on how the structure of the interaction network among ant workers affects the foraging regulation of colonies of the red harvester ant, Pogonmyrmex barbatus. In addition, I will discuss the causes and consequences of individual variation in the collective behavior of colonies of the black harvester ant, Messor andrei. In both cases, variation at small local scales translates into variation at the system level, creating a behaviorally diverse population.
