Hyperscaling of spatial fluctuations constrains the development of urban populations
Wout Merbis, Fernando A. N. Santos, Jay Armas +2
Urban populations exhibit fractal organization and systematic scaling regularities, yet the scaling exponents reported across cities vary substantially, challenging existing theory…
Complex information dynamics of epidemic spreading in low-dimensional networks
Wout Merbis, Manlio de Domenico
The statistical field theory of information dynamics on complex networks concerns the dynamical evolution of large classes of models of complex systems. Previous work has focused o…
Symmetric preferences, asymmetric outcomes: Tipping dynamics in an open-city segregation model
Fabio van Dissel, Tuan Minh Pham, Wout Merbis
Schelling's model of segregation demonstrates that even in the absence of social or governmental interventions, individuals with mild in-group preferences can self-organize into st…
Soft hairy warped black hole entropy
Daniel Grumiller, Philip Hacker, Wout Merbis
We reconsider warped black hole solutions in topologically massive gravity and find novel boundary conditions that allow for soft hairy excitations on the horizon. To compute the a…
Free energy of topologically massive gravity and flat space holography
Daniel Grumiller, Wout Merbis
We calculate the free energy from the on-shell action for topologically massive gravity with negative and vanishing cosmological constant, thereby providing a first principles deri…
Minimal Massive 3D Gravity
Eric Bergshoeff, Olaf Hohm, Wout Merbis +2
We present an alternative to Topologically Massive Gravity (TMG) with the same "minimal" bulk properties; i.e. a single local degree of freedom that is realized as a massive gravit…
