Kinks of open superstring field theory
Gianluca Calcagni, Giuseppe Nardelli
We construct approximate kink solutions of supersymmetric open string field theory at lowest level when non-local operators in the tachyon effective action are fully taken into acc…
A new method for fast computing unbiased estimators of cumulants
E. Di Nardo, G. Guarino, D. Senato
We propose new algorithms for generating -statistics, multivariate -statistics, polykays and multivariate polykays. The resulting computational times are very fast compared w…
Symbolic computation of moments of sampling distributions
E. Di Nardo, G. Guarino, D. Senato
By means of the notion of umbrae indexed by multisets, a general method to express estimators and their products in terms of power sums is derived. A connection between the notion…
Nonlocal instantons and solitons in string models
Gianluca Calcagni, Giuseppe Nardelli
We study a class of nonlocal systems which can be described by a local scalar field diffusing in an auxiliary radial dimension. As examples p-adic, open and boundary string field t…
Localization of nonlocal theories
Gianluca Calcagni, Michele Montobbio, Giuseppe Nardelli
We show that a certain class of nonlocal scalar models, with a kinetic operator inspired by string field theory, is equivalent to a system which is local in the coordinates but non…
Bose-Einstein condensates in 1D optical lattices: compressibility, Bloch bands and elementary excitations
Meret Kraemer, Chiara Menotti, Lev Pitaevskii +1
We discuss the Bloch-state solutions of the stationary Gross-Pitaevskii equation and of the Bogoliubov equations for a Bose-Einstein condensate in the presence of a one-dimensional…
