Unsupervised Bayesian Ising Approximation for revealing the neural dictionary in songbirds
Damián G. Hernández, Samuel J. Sober, Ilya Nemenman
The problem of deciphering how low-level patterns (action potentials in the brain, amino acids in a protein, etc.) drive high-level biological features (sensorimotor behavior, enzy…
Analytical Model for Light Modulating Impedance Spectroscopy (LIMIS) in All-Solid-State p-n Junction Solar Cells at Open-Circuit
Osbel Almora, Daniel Miravet, Gebhard J. Matt +2
Non-circuit theory drift-diffusion numerical simulation of standard potentiostatic impedance spectroscopy (IS) is a well-known strategy for characterization of materials and electr…
Negative thermal expansion of nanoporous anodic aluminum oxide membranes
L. Forzani, C. A. Ramos, E. Vassallo Brigneti +2
We have measured the thermal expansion of Ni nanowires electrodeposited into self-organized nanoporous amorphous aluminum oxide (AAO) membranes without Al substrate using X-ray dif…
Kondo physics of magnetic adatoms on metallic surfaces when the onset of the surface conduction density of states crosses the Fermi level
J. Fernández, P. Roura-Bas
We study the role of the onset of Shockley states, , belonging to (111) surfaces of Cu, Ag and Au in the Kondo effect when a magnetic impurity is deposited on them. When …
Spectral fingerprints of the non-linear dynamics of driven superconductors with dissipation
H. P. Ojeda Collado, Gonzalo Usaj, José Lorenzana +1
We study the out-of-equilibrium dynamics of a BCS superconductor in the presence of a periodic drive with a frequency larger than the equilibrium superconducting gap and an e…
Reflections on the covariance of modified teleparallel theories of gravity
Cecilia Bejarano, Rafael Ferraro, Franco Fiorini +1
We review the current status of the Lorentz covariance in teleparallel and modified teleparallel theories of gravity, and discuss the controversial features of the different approa…
