Twist/Writhe Partitioning in a Coarse-Grained DNA Minicircle Model

Mehmet Sayar, Baris Avsaroglu, Alkan Kabakcioglu

Here we present a systematic study of supercoil formation in DNA minicircles under varying linking number by using molecular dynamics simulations of a two-bead coarse-grained model…

Crystallization of ion clouds in octupole traps: structural transitions, core melting, and scaling laws

Florent Calvo, Caroline Champenois, Ersin Yurtsever

The stable structures and melting properties of ion clouds in isotropic octupole traps are investigated using a combination of semi-analytical and numerical models, with a particul…

Phase diagram of the hardcore Bose-Hubbard model on a checkerboard superlattice

Itay Hen, M. Iskin, Marcos Rigol

We obtain the complete phase diagram of the hardcore Bose-Hubbard model in the presence of a period-two superlattice in two and three dimensions. First we acquire the phase boundar…

Examples of planar tight contact structures with support norm one

Tolga Etgü, Yanki Lekili

We exhibit an infinite family of tight contact structures with the property that none of the supporting open books minimizes the genus and maximizes the Euler characteristic of the…

Active control of focal length and beam deflection in a metallic nano-slit array lens with multiple sources

Arif E. Cetin, Kaan Guven, Ozgur E. Mustecaplioglu

We propose a surface plasmon-polariton based nano-rod array lens structure that incorporates two additional lateral input channels, with the ability to control the focal length and…

Foliations of Hyperbolic Space by Constant Mean Curvature Hypersurfaces

Baris Coskunuzer

We show that the constant mean curvature hypersurfaces in the hyperbolic n-space spanning the boundary of a star shaped C^{1,1} domain in the asymptotic sphere give a foliation of…
