Finite-size effects on the hadron-quark mixed phase
  We show that the hadron-quark mixed phase is restricted to narrow range of baryon chemical potential by the charge screening effect.   Accordingly the mixed phase expected in hadron-quark hybrid stars should be narrow. Although the screening would not have large effect in bulk properties of the star such as mass or radius, it change the internal structure of the star very much, which may be tested by the cooling curve, glitch phenomena or gravitational waves.
