A Weyl type formula for Fourier spectra and frames
Alex Iosevich, Mihail N. Kolountzakis
We prove qualitative and quantitative results concerning the asymptotic density in dilates of centered convex bodies of the frequency vectors of orthogonal exponential bases and fr…
First results from a Chandra survey of the 'Bar' region of the SMC
A. Zezas, J. C. McDowell, D. Hadzidimitriou +3
We present the first results from a Chandra survey of the central region of the Small Magellanic Cloud. We detect a total of 122 sources down to a limiting luminosity of ~4.3x10^{3…
Breather lattices as pseudospin glasses
M. Eleftheriou, G. P. Tsironis
We study the thermodynamics of discrete breathers by transforming a lattice of weakly coupled nonlinear oscillators into an effective Ising pseudospin model. We introduce a replica…
Solitons, solitonic vortices, and vortex rings in a confined Bose-Einstein condensate
S. Komineas, N. Papanicolaou
Quasi-one-dimensional solitons that may occur in an elongated Bose-Einstein condensate become unstable at high particle density. We study two basic modes of instability and the cor…
Distance sets corresponding to convex bodies
Mihail N. Kolountzakis
Suppose that $K \subseteq \RR^d$ is a 0-symmetric convex body which defines the usual norm $$ \Norm{x}_K = \sup\Set{t\ge 0: x \notin tK} $$ on $\RR^d$. Let also $A\subseteq\RR^d$ b…
