Stabilizing copper sites in coordination polymers toward efficient electrochemical C-C coupling
Nature Communications, 2023 Typically, Cu catalysts agglomerate under electrochemical conditions. Here, the authors report a coordination polymer catalyst with neighboring Cu sites which remain isolated and reduce CO2 to C2H4 with high selectivity and ...

Data‐driven performance metrics for neural network learning
International Journal of Adaptive Control and Signal Processing, EarlyView., 2023 Summary Effectiveness of data‐driven neural learning in terms of both local mimima trapping and convergence rate is addressed. Such issues are investigated in a case study involving the training of one‐hidden‐layer feedforward neural networks with the extended Kalman filter, which reduces the search for the optimal network parameters to a state ...

Quantum noise for Faraday light–matter interfaces [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2012 In light matter interfaces based on the Faraday effect quite a number of quantum information protocols have been successfully demonstrated. In order to further increase the performance and fidelities achieved in these protocols a deeper understanding of the relevant noise and decoherence processes needs to be gained.

Absence of Physical Walls in Hot Gauge Theories [PDF]
, 1995 This paper shows that there are no {\em physical} walls in the deconfined, high-temperature phase of $Z(2)$ lattice gauge theory. In a Hamiltonian formulation, the interface in the Wilson lines is not physical.
