Nonlinear localized flat-band modes with spin-orbit coupling

G. Gligorić, A. Maluckov, Lj. Hadžievski, Sergej Flach, Boris A. Malomed
2016 Physical review B  
We report the coexistence and properties of stable compact localized states (CLSs) and discrete solitons (DSs) for nonlinear spinor waves on a flatband network with spin-orbit coupling (SOC).  ...  Inside of the minigap, the CLS and DS families are stable in narrow areas adjacent to the FB. Deep inside the semi-infinite gap, both the CLSs and DSs are stable too.  ...  In fact, their shapes are close too, apart from the presence of the exponentially decaying tails in the DSs, which are absent in the CLSs.  ...

Query Matrices for Retrieving Binary Vectors Based on the Hamming Distance Oracle [article]

Vinay Anant Vaishampayan
2012 arXiv   pre-print
We show that our recursive and algebraic construction results in query ratios arbitrarily close to zero. Our construction is based on codes of constant weight.  ...  We consider the query ratio m/n to be our figure of merit and derive upper bounds on the query ratio by explicitly constructing (m,n) query matrices.  ...  The similarity of our problem to the n-DSS set problem comes from the observation that for an n-DSS set, the only {−1, 0, 1}-valued vector y for which n i=1 r i y i = 0 is the all zero vector y = 0.  ...
