Elastic theory of pinned flux lattices.
The pinning of flux lattices by weak impurity disorder is studied in the absence of free dislocations using both the gaussian variational method and, to O(ǫ = 4 − d), the functional renormalization group. We find universal logarithmic growth of displacements for 2 < d < 4: 〈u(x) − u(0)〉2 ∼ Ad log |x| and persistence of algebraic quasi-long range translational order. When the two methods can be ...
متن کاملElastic theory of flux lattices in presence of weak disorder
The effect of weak impurity disorder on flux lattices at equilibrium is studied quantitatively in the absence of free dislocations using both the Gaussian variational method and the renormalization group. Our results for the mean square relative displacements B̃(x) = 〈u(x)− u(0)〉2 clarify the nature of the crossovers with distance. We find three regimes: (i) a short distance regime (“Larkin regi...
متن کاملac Dynamics of a Pinned Flux-Line Lattice
The surface impedance of 2H-NbSe2 in the mixed state was measured over the frequency range 10–3000 MHz in fields up to 2 T. A crossover between pinned and viscous flux-line dynamics is observed at a pinning frequency, vp . The measured vp is compared to that predicted by a singleparticle “washboard potential” model of pinning. When the flux lattice is in an ordered state, vp is in good agreemen...
متن کاملStructure of an Elastic Lattice Pinned by Hopping Defects
The translational order in a three-dimensional lattice pinned by hopping defects is studied. It is suggested that the equilibrium state of the lattice crosses from a glass to a crystal on the rate of hopping. It is argued that such a transition may exist in flux lattices of hightemperature superconductors due to the hopping of oxygen. PACS. 74.60.Ge Flux pinning, flux creep, and flux lattice dy...
متن کاملPinned modes in lossy lattices with local gain and nonlinearity.
We introduce a discrete linear lossy system with an embedded "hot spot" (HS), i.e., a site carrying linear gain and complex cubic nonlinearity. The system can be used to model an array of optical or plasmonic waveguides, where selective excitation of particular cores is possible. Localized modes pinned to the HS are constructed in an implicit analytical form, and their stability is investigated...
