    Abstract
    Thin elastic sheets bend easily and, if they are patterned with cuts, can deform in sophisticated ways. Here we show that carefully tuning the location and arrangement of cuts within thin sheets enables the design of mechanical actuators that scale down to atomically-thin 2D materials. We first show that by understanding the mechanics of a single non-propagating crack in a sheet, we can generate four fundamental forms of linear actuation: roll, pitch, yaw, and lift. Our analytical model shows that these deformations are only weakly dependent on thickness, which we confirm with experiments on centimeter-scale objects and molecular dynamics simulations of graphene and MoS₂ nanoscale sheets. We show how the interactions between non-propagating cracks can enable either lift or rotation, and we use a combination of experiments, theory, continuum computational analysis, and molecular dynamics simulations to provide mechanistic insights into the geometric and topological design of kirigami actuators.

      Kondo effect in d-wave superconductors 

      Polkovnikov, Anatoli (AMERICAN PHYSICAL SOC, 2002-02-01)
      We present theoretical investigation of a single magnetic impurity in a d-wave superconductor using the large-N limit. It is shown that Kondo screening occurs only in the presence of particle-hole asymmetry. We find ...

      Vanishing spin stiffness in the spin-1/2 Heisenberg chain for any nonzero temperature 

      Carmelo, J.M.P.; Prosen, T.; Campbell, D.K. (American Physical Society, 2015-10-30)
      Whether at the zero spin density m = 0 and finite temperatures T > 0 the spin stiffness of the spin- 1 / 2 X X X chain is finite or vanishes remains an unsolved and controversial issue, as different approaches yield ...

      Lane, Kenneth D. (ELSEVIER SCIENCE BV, 1995-09-14)
      I discuss production and detection at the Tevatron collider of pairs of light (MπT = 100–200GeV) color-singlet technipions that are expected in all nonminimal models of technicolor. Gluon fusion production rates can be as ...
