Resonances for Open Quantum Maps and a Fractal Uncertainty Principle

Abstract: We study eigenvalues of quantum open baker's maps with trapped sets given by linear arithmetic Cantor sets of dimensions δ ∈ (0, 1). We show that the size of the spectral gap is strictly greater than the standard bound max(0, 1 2 − δ) for all values of δ, which is the first result of this kind. The size of the improvement is determined from a fractal uncertainty principle and can be computed for any given Cantor set. We next show a fractal Weyl upper bound for the number of eigenvalues in annuli, with exponent… Show more

“…In the example presented there the numerically computed best exponent in FUP (3.43) is sharp. Some other examples in [74] show however that it is not always the case. We will return to open quantum maps in Sect.…”
