#LB E, mais uma vez, a minha tootline estš fazendo eu me sentir um idoso kkkk.
E, sim, é a melhor música dela, o coral é ótimo e a letra tem uma certa intensidade.
Algum tempo depois, a Madonna mudou de estilo e a partir daí só fez músicas horríveis rs.

Thermal quenching of classical and semiclassical scrambling
Quantum scrambling often gives rise to short-time exponential growth in out-of-time-ordered correlators (OTOCs). The scrambling rate over an isolated saddle point at finite temperature is shown here to be reduced by a hierarchy of quenching processes. Two of these appear in the classical limit, where escape from the neighbourhood of the saddle reduces the rate by a factor of two, and thermal fluctuations around the saddle reduce it further; a third process can be explained semiclassically as ar…

Van Hove singularities in the density of states of a chaotic dynamical system
The statistics of a chaotic recursion relation can be predicted by constructing an associated sequence of periodic elliptic operators. For such operators, the density of states is well understood, can be computed straightforwardly and explicit formulas can often be derived. The example studied here is a non-linear recursion relation which can be related to a sequence of periodic operators generated by a Fibonacci tiling rule. This link is used to derive an explicit formula for the limiting dist…
