  This study investigates in detail the finite-size scaling of the
two-dimensional irrationally frustrated XY model. By means of Monte Carlo
simulations with entropic sampling, we examine the size dependence of the
specific heat, and find remarkable deviation from the conventional finite-size
scaling theory, which reveals novel intrinsic finite-size effects. Relaxation
dynamics of the system is also considered, and correspondingly, finite-size
scaling of the relaxation time is examined, again giving evidence for the
intrinsic finite-size effects and suggesting a zero-temperature glass
transition.
