Synchronization dynamics on the picosecond timescale in coupled Josephson junction neurons
Ken Segall, Matthew LeGro, Steven Kaplan +4
Conventional digital computation is rapidly approaching physical limits for speed and energy dissipation. Here we fabricate and test a simple neuromorphic circuit that models neuro…
Josephson junction simulation of neurons
Patrick Crotty, Daniel Schult, Ken Segall
With the goal of understanding the intricate behavior and dynamics of collections of neurons, we present superconducting circuits containing Josephson junctions that model biologic…
Optimization of the leak conductance in the squid giant axon
Jeffrey Seely, Patrick Crotty
We report on a theoretical study showing that the leak conductance density, $\GL$, in the squid giant axon appears to be optimal for the action potential firing frequency. More pre…
Current cosmological bounds on neutrino masses and relativistic relics
Patrick Crotty, Julien Lesgourgues, Sergio Pastor
We combine the most recent observations of large-scale structure (2dF and SDSS galaxy surveys) and cosmic microwave anisotropies (WMAP and ACBAR) to put constraints on flat cosmolo…
Bounds on isocurvature perturbations from CMB and LSS data
P. Crotty, J. Garcia-Bellido, J. Lesgourgues +1
We obtain very stringent bounds on the possible cold dark matter, baryon and neutrino isocurvature contributions to the primordial fluctuations in the Universe, using recent cosmic…
Does the small CMB quadrupole moment suggest new physics?
James M. Cline, Patrick Crotty, Julien Lesgourgues
Motivated by WMAP's confirmation of an anomalously low value of the quadrupole moment of the CMB temperature fluctuations, we investigate the effects on the CMB of cutting off the…
