  • Caught in the act: Astronomers find a rare supernova 'impostor' in a nearby galaxy

  • Materials by design: A radical shift in transforming bulk matter into useful technology
    Folding an octahedron out of a linear chain A Typical chain configurations that result after iterating Eq 2 Numbers indicate the iteration number Early on the polymer configurations are dominated by thermal energy and random yet as the interaction strengths increase and differentiate more structured objects appear and ultimately only the octahedron configuration exists iterations 190 210 B Plotting the median percentage of deviation between the polymer s radius of gyration Rg and the radius of gyration for an octahedron Roct at each iteration shows that the optimizer again produces a monotonic decrease at each step with an effectively exponential convergence in the last 30 iterations By the last 10 iterations the median deviation from a perfect octahedron is roughly 1 C In plotting the coupling constants against iteration number we find that the optimizer adjusts coupling constants in groups It is clear that the active coupling constants form the contact network for an octahedron C Inset Miskin MZ et al 2016 Turning statistical physics models into materials design engines Proc Natl Acad Sci USA 113 1 34 39 However Miskin stresses this view completely ignores the microstates and it turns out that you can build a much more efficient optimization program by thinking about control parameters as a way to alter the likelihood of microstates To design the material you therefore tweak the parameters so that the material is more likely to be in microstates with the target behavior This idea is the kernel of our approach In other words the scientists created a formalism that addresses materials design at the level of micro state information an advance yielding a program broad enough to address the range of materials that are well described by statistical physics that is achieved higher efficiency as a result of having access to the additional microstate configuration information The paper describes novel possible solutions for a range of complex optimization and design problems concerning both in and out of equilibrium materials Probably the two most fascinating solutions presented in the paper address the polymer folding problem and the directed self assembly problem Miskin tells Phys org In the polymer folding problem we asked our optimizer to tune the interaction strengths between 6 beads attached to each other along a linear chain The interactions are attractive so if you make them strong enough the chain will fold itself up into a compact shape The goal was to make the chain fold into a specific shape an octahedron a three dimensional shape having eight plane faces especially a regular solid figure with eight equal triangular faces It s an interesting problem It s well known that simply making all the interactions large will not produce an octahedral geometry rather to generate octahedron one needs to develop the interactions into three separate families This took hard work from the colloidal self assembly community to show that this was the best way to do it so it was very exciting for us when our optimizer not only produced a virtually identical motif but managed to yield the result in the span of hours The directed self assembly problem is a similar story In this case you have a polymer made of two types of beads he continues The goal is to pattern a substrate with a thin strip that has affinity for a particular one of those two beads By setting the strip width and the strength of affinity just right you can get the polymer to self assemble into stripes containing only one polymer type followed by a stripe of the other polymer type and so on This idea holds serious promise as a next generation manufacturing technology for semiconductors he explains because these stripes are on the order of nanometers in size By using the polymer stripes as stencils or masks the production of next generation circuits or hard drive media with features significantly smaller than what current processing techniques allow could be considered What we found was that not only can our optimizer produce solutions to the problem of tailoring interaction strengths for this kind of directed self assembly but that it does so between 5 130x faster than approaches we ve tried in the past To put this into context solving a directed self assembly problem in the past took us roughly one week but we can now solve this in just under 12 hours In addition the paper reports that new materials design directions made possible by the de novo approach also enable processing conditions to be optimized If a material can easily get trapped in a metastable state or if that metastable state possesses desirable material properties tuning the processing conditions of that material is a key part of its design Miskin says an example being polymer folding notably the folding of biomolecules While setting the interactions of elements in a polymer chain may not be enough to produce a targeted structure because the polymer may get stuck in a metastable configuration our approach could be applied to not only select the interactions for elements within a protein but to also generate a processing protocol that yields a target protein structure given those specific interactions An example of the latter that is in which a metastable state produces desirable properties is given by quenching metals in particular steel In this case we could envision our approach as a means of generating annealing or quenching protocols that yield optimized final materials The publication points out that that their framework provides an intuitive solution despite the context of a complex search landscape that have led other optimization schemes to struggle or fail Our experience in the past has been that it can be difficult to get started building design engines for a new material Miskin relates If the problem isn t posed the right way or the optimizer isn t appropriately tailored it can require a substantial investment of time to construct an optimization scheme that actually works Our formalism works broadly over a

5 8 Feb 09 2016 In quantum entanglement two particles are correlated in such a way that any action on one of them affects the other even when they are far apart Writer you must be joking It doesn t affect the other particle it merely predicts the state of the other particle if we measure the state of this one Else the information exchange would be possible and it is not possible Everyone with undergrad in physics should know this Back to school tech writer Lisa Zyga my girl Else very interesting research Like it promile 3 4 5 5 Feb 09 2016 It doesn t affect the other particle it merely predicts the state of the other particle if we measure the state of this one If it determines the state of particles and its changes it just means it affects it or not Could something affect the state

to somewhere very far away from me You open box 2 to reveal the banana This means that I have the orange in box 1 At no point have you travelled superliminally to interfere with my box it is literally the only possibility that I have the orange given that you have the banana The only thing you have affected is your knowledge of the combined system shavera 3 5 4 Feb 09 2016 Actually NoStrings you re not quite correct either If it merely predicts the state then we couldn t exchange information either because it doesn t carry any new information The bigger picture is that entanglement means that there is a state encoded in the system of two particles that cannot be gleaned from either one particle alone The classic example is creating particles with entangled spin up and down After creating them Alice may flip one upside down rotate it along the X or Y axis or leave it unchanged thus having 4 possible states Bob measures his particle but doesn t know which rotation Alice performed Alice measures hers tells Bob her results and Bob can use that answer to determine which rotation Alice performed The catch is that the relationship changes if the particles have an explicit state prior to being measured no superposition of states AND that state information is transmitted at c or slower Experiments don t show such a relationship promile 3 5 2 Feb 09 2016 NoStrings What you just said is the example of anti correlation not entanglement You don t need any special physics for explanation of correlation the quantum physics the less because the anti correlation was established long before the actual observation by intentional placing of both fruit pieces into their separate boxes But the gaining this knowledge is not possible without transfer of some amount of energy no matter how minute it is The entanglement provides that this energy affects the states of both pieces of fruit at the same moment The paradox here is that
