Metastability of Discrete-Symmetry Flocks
Brieuc Benvegnen, Omer Granek, Sunghan Ro +6
We study the stability of the ordered phase of flocking models with a scalar order parameter. Using both the active Ising model and a hydrodynamic description, we show that droplet…
Supercoil formation in DNA denaturation
A. Kabakcioglu, E. Orlandini, D. Mukamel
We generalize the Poland-Scheraga (PS) model to the case of a circular DNA, taking into account the twisting of the two strains around each other. Guided by recent single-molecule…
Reply to Comment on "Why is the DNA Transition First Order?" and "Griffiths Singularities in Unbinding of Strongly Disordered Polymers" by M. Ya. Azbel
Y. Kafri, D. Mukamel, L. Peliti
It is shown that the various claims made in the comment by M. Ya. Azbel (physics/0403106) on the two publications Phys. Rev. Lett. 91, 055502 (2003) and Phys. Rev. Lett. 85, 4988 (…
Why is the DNA Denaturation Transition First Order?
Yariv Kafri, David Mukamel, Luca Peliti
We study a model for the denaturation transition of DNA in which the molecules are considered as composed of a sequence of alternating bound segments and denaturated loops. We take…
Gel-Electrophoresis and Diffusion of Ring-Shaped DNA
Uri Alon, David Mukamel
A model for the motion of ring-shaped DNA in a gel is introduced and studied by numerical simulations and a mean-field approximation. The ring motion is mediated by finger-shaped l…
