Measurement of Casimir–Lifshitz forces with high enough precision at separations below 50 nm is problematic due to the snap-in instability. The method of the adhered cantilever is not influenced by this problem. This method has demonstrated a r...

The Boltzmann–Loschmidt dispute in 1876–1877 concerned the problem of the time reversal of thermalization in time-reversible classical equations of motion. Here, 150 years later, we revisit this problem in the context of quantum computing...

The dynamic critical exponent z describes the divergence of correlation times near a continuous phase transition. Obtaining accurate estimates of z from noisy time series is complex, especially when computational resources are limited. We compare mac...
Quantum mechanics is among the most successful physical theories, yet its formulation and empirical testing rely on classical structures. Following Lev Landau and Niels Bohr, this reliance is not merely pragmatic: quantum observables acquire empirica...
