Nonexistence of closed timelike geodesics in Kerr spacetimes

Autor: Sanzeni, Giulio

Publikováno v: J. Math. Phys. 65, 082503 (2024)

The Kerr-star spacetime is the extension over the horizons and in the negative radial region of the Kerr spacetime. Despite the presence of closed timelike curves below the inner horizon, we prove that the timelike geodesics cannot be closed in the K

Emergence of irregular activity in networks of strongly coupled conductance-based neurons

Autor: Sanzeni, Alessandro, Histed, Mark H, Brunel, Nicolas

Cortical neurons are characterized by irregular firing and a broad distribution of rates. The balanced state model explains these observations with a cancellation of mean excitatory and inhibitory currents, which makes fluctuations drive firing. In n
