Enhancing synchronization by optimal correlated noise
Sherwood Martineau, Tim Saffold, Timothy T. Chang +1
From the flashes of fireflies to Josephson junctions and power infrastructure, networks of coupled phase oscillators provide a powerful framework to describe synchronization phenom…
Dual communities in spatial networks
Franz Kaiser, Philipp C. Böttcher, Henrik Ronellenfitsch +2
Both human-made and natural supply systems, such as power grids and leaf venation networks, are built to operate reliably under changing external conditions. Many of these spatial…
Discontinuous transition to loop formation in optimal supply networks
Franz Kaiser, Henrik Ronellenfitsch, Dirk Witthaut
The structure and design of optimal supply networks is an important topic in complex networks research. A fundamental trait of natural and man-made networks is the emergence of loo…
Optimal elasticity of biological networks
Henrik Ronellenfitsch
Reinforced elastic sheets surround us in daily life, from concrete shell buildings to biological structures such as the arthropod exoskeleton or the venation network of dicotyledon…
Spectral Design of Active Mechanical and Electrical Metamaterials
Henrik Ronellenfitsch, Jörn Dunkel
Active matter is ubiquitous in biology and becomes increasingly more important in materials science. While numerous active systems have been investigated in detail both experimenta…
Chiral topological phases in designed mechanical networks
Henrik Ronellenfitsch, Jörn Dunkel
Mass-spring networks (MSNs) have long been used as approximate descriptions of many biological and engineered systems, from actomyosin networks to mechanical trusses. In the last d…
Active topolectrical circuits
Tejas Kotwal, Fischer Moseley, Alexander Stegmaier +6
The transfer of topological concepts from the quantum world to classical mechanical and electronic systems has opened fundamentally new approaches to protected information transmis…
Non-Local Impact of Link Failures in Linear Flow Networks
Julius Strake, Franz Kaiser, Farnaz Basiri +2
The failure of a single link can degrade the operation of a supply network up to the point of complete collapse. Yet, the interplay between network topology and locality of the res…
Optimal noise-canceling networks
Henrik Ronellenfitsch, Jörn Dunkel, Michael Wilczek
Natural and artificial networks, from the cerebral cortex to large-scale power grids, face the challenge of converting noisy inputs into robust signals. The input fluctuations ofte…
Autonomous actuation of zero modes in mechanical networks far from equilibrium
Francis G. Woodhouse, Henrik Ronellenfitsch, Jörn Dunkel
A zero mode, or floppy mode, is a non-trivial coupling of mechanical components yielding a degree of freedom with no resistance to deformation. Engineered zero modes have the poten…
The limits of multifunctionality in tunable networks
Jason W. Rocks, Henrik Ronellenfitsch, Andrea J. Liu +2
Nature is rife with networks that are functionally optimized to propagate inputs in order to perform specific tasks. Whether via genetic evolution or dynamic adaptation, many netwo…
Inverse Design of Discrete Mechanical Metamaterials
Henrik Ronellenfitsch, Norbert Stoop, Josephine Yu +2
Mechanical and phononic metamaterials exhibiting negative elastic moduli, gapped vibrational spectra, or topologically protected modes enable precise control of structural and acou…
Phenotypes of vascular flow networks
Henrik Ronellenfitsch, Eleni Katifori
Complex distribution networks are pervasive in biology. Examples include nutrient transport in the slime mold \emph{Physarum polycephalum} as well as mammalian and plant venation.…
Linear Optimal Power Flow Using Cycle Flows
Jonas Hörsch, Henrik Ronellenfitsch, Dirk Witthaut +1
Linear optimal power flow (LOPF) algorithms use a linearization of the alternating current (AC) load flow equations to optimize generator dispatch in a network subject to the loadi…
Embedding of biological distribution networks with differing environmental constraints
Lia Papadopoulos, Pablo Blinder, Henrik Ronellenfitsch +4
Distribution networks -- from vasculature to urban transportation systems -- are prevalent in both the natural and consumer worlds. These systems are intrinsically physical in comp…
Network susceptibilities: theory and applications
Debsankha Manik, Martin Rohden, Henrik Ronellenfitsch +4
We introduce the concept of network susceptibilities quantifying the response of the collective dy- namics of a network to small parameter changes. We distinguish two types of susc…
A trophallaxis inspired model for distributed transport between randomly interacting agents
Johannes Gräwer, Henrik Ronellenfitsch, Marco G. Mazza +1
A trophallaxis inspired model for distributed transport between randomly interacting agents Trophallaxis, the regurgitation and mouth to mouth transfer of liquid food between membe…
Dual theory of transmission line outages
Henrik Ronellenfitsch, Debsankha Manik, Jonas Hörsch +2
A new graph dual formalism is presented for the analysis of line outages in electricity networks. The dual formalism is based on a consideration of the flows around closed cycles i…
Global Optimization, Local Adaptation, and the Role of Growth in Distribution Networks
Henrik Ronellenfitsch, Eleni Katifori
Highly-optimized complex transport networks serve crucial functions in many man-made and natural systems such as power grids and plant or animal vasculature. Often, the relevant op…
A Dual Method for Computing Power Transfer Distribution Factors
Henrik Ronellenfitsch, Marc Timme, Dirk Witthaut
Power Transfer Distribution Factors (PTDFs) play a crucial role in power grid security analysis, planning, and redispatch. Fast calculation of the PTDFs is therefore of great impor…
Topological phenotypes constitute a new dimension in the phenotypic space of leaf venation networks
Henrik Ronellenfitsch, Jana Lasser, Douglas C. Daly +1
The leaves of angiosperms contain highly complex venation networks consisting of recursively nested, hierarchically organized loops. We describe a new phenotypic trait of reticulat…
Generalised Mathieu Moonshine
Matthias R. Gaberdiel, Daniel Persson, Henrik Ronellenfitsch +1
The Mathieu twisted twining genera, i.e. the analogues of Norton's generalised Moonshine functions, are constructed for the elliptic genus of K3. It is shown that they satisfy the…
