Self-organized criticality in neural networks from activity-based rewiring
Stefan Landmann, Lorenz Baumgarten, Stefan Bornholdt
Neural systems process information in a dynamical regime between silence and chaotic dynamics. This has lead to the criticality hypothesis which suggests that neural systems reach…

Shallow shell theory of the buckling energy barrier: from the Pogorelov state to softening and imperfection sensitivity close to the buckling pressure
Lorenz Baumgarten, Jan Kierfeld
We study the axisymmetric response of a complete spherical shell under homogeneous compressive pressure to an additional point force. For a pressure below the classical cri…

Buckling of thermally fluctuating spherical shells: Parameter renormalization and thermally activated barrier crossing
Lorenz Baumgarten, Jan Kierfeld
We study the influence of thermal fluctuations on the buckling behavior of thin elastic capsules with spherical rest shape. Thermal fluctuations affect the buckling instability by…
