Rigidity and auxeticity transitions in networks with strong bond-bending interactions
Robbie Rens, Edan Lerner
A widely-studied model for gels or biopolymeric fibrous materials are networks with central force interactions, such as Hookean springs. Less commonly studied are materials whose m…

Magnetic properties and temperature variation of spectra in the Hubbard model
A Sherman
Using the strong coupling diagram technique, magnetic and spectral properties of the two-dimensional repulsive Hubbard model are investigated in the ranges of repulsions $t\leq U\l…
