An intermediate phase in DNA melting
Richard A. Neher, Ulrich Gerland
We predict a novel temperature-driven phase transition of DNA below the melting transition. The additional, intermediate phase exists for repetitive sequences, when the two strands…
Oscillations in molecular motor assemblies
Andrej Vilfan, Erwin Frey
Autonomous oscillations in biological systems may have a biochemical origin or result from an interplay between force-generating and visco-elastic elements. In molecular motor asse…
Minimality and irreducibility of symplectic four-manifolds
M. J. D. Hamilton, D. Kotschick
We prove that all minimal symplectic four-manifolds are essentially irreducible. We also clarify the relationship between holomorphic and symplectic minimality of Kähler surfaces.…
Experimental Analysis of a 4-Qubit Cluster State
Nikolai Kiesel, Christian Schmid, Ulrich Weber +4
Linear optics quantum logic operations enabled the observation of a four-photon cluster state. We prove genuine four-partite entanglement and study its persistency, demonstrating r…
Fluctuations and Correlations in Lattice Models for Predator-Prey Interaction
Mauro Mobilia, Ivan T. Georgiev, Uwe C. Tauber
Including spatial structure and stochastic noise invalidates the classical Lotka-Volterra picture of stable regular population cycles emerging in models for predator-prey interacti…
An exact Lagrangian integral for the Newtonian gravitational field strength
Thomas Buchert
An exact expression for the gravitational field strength in a self-gravitating dust continuum is derived within the Lagrangian picture of continuum mechanics. From the Euler-Newton…
