1001.2096 | let @xmath0 be a quadratic form of signature @xmath1 , @xmath2 a non - elementary discrete subgroup of @xmath3 and @xmath4 a non - zero vector with the orbit @xmath5 discrete . we introduce the notion of the @xmath2-skinning size @xmath6 of @xmath7 , and we compute an asymptotic formula ( as @xmath8 ) for the number of... | 213 |
quant-ph0101069 | we study the situation where two point like mirrors are placed in the vacuum state of a scalar field in a two - dimensional spacetime . describing the scattering upon the mirrors by transmittivity and reflectivity functions obeying unitarity , causality and high frequency transparency conditions , we compute the fluctu... | 125 |
astro-ph0009389 | we generalize the derivation of dynamo coefficient @xmath0 of field ( 1999 ) to include the following two aspects : first , the de - correlation times of velocity field and magnetic field are different ; second , the magnetic prandtl number can be arbitrary . we find that the contributions of velocity field and magneti... | 220 |
