Non-parametric causal inference for bivariate time series
James M. McCracken, Robert S. Weigel
We introduce new quantities for exploratory causal inference between bivariate time series. The quantities, called penchants and leanings, are computationally straightforward to ap…
Convergent Cross-Mapping and Pairwise Asymmetric Inference
James M. McCracken, Robert S. Weigel
Convergent Cross-Mapping (CCM) is a technique for computing specific kinds of correlations between sets of times series. It was introduced by Sugihara et al. and is reported to be…
Tests For Complete Positivity of Quantum Channels
James M. McCracken
A quantum channel will have a Choi representation from which the complete positivity (CP) can be determined in a number of different ways. Every method relies on Choi's proof which…
Hamiltonian Composite Dynamics Can Almost Always Lead To Negative Reduced Dynamics
James M. McCracken
Complete positivity is a ubiquitous assumption in the study of quantum systems interacting with the environment, despite repeated efforts to point out that the assumption is not em…
Quantum Channel Negativity as a Measure of System-Bath Coupling and Correlation
James M. McCracken
Complete positivity is a ubiquitous assumption in the study of quantum systems interacting with the environment, but the lack of complete positivity of a quantum evolution (called…
Could light harvesting complexes exhibit non-classical effects at room temperature?
Mark M. Wilde, James M. McCracken, Ari Mizel
Mounting experimental and theoretical evidence suggests that coherent quantum effects play a role in the efficient transfer of an excitation from a chlorosome antenna to a reaction…
