Stability and energetics of 2D surface crystals in liquid AuSi thin films and nanoscale droplets
Hailong Wang, Alireza Shahabi, Alain Karma +1
Segregation at surfaces of metal-covalent binary liquids is often non-classical and in extreme cases such as AuSi, the surface crystallizes above the melting point. In this study,…
Shaping van der Waals nanoribbons via torsional constraints: Scrolls, folds and supercoils
Alireza Shahabi, Hailong Wang, Moneesh Upmanyu
Interplay between structure and function in atomically thin crystalline nanoribbons is sensitive to their conformations yet the ability to prescribe them is a formidable challenge.…
Carbon nanotube plectonemes: Loops of twisted helices
Alireza Shahabi, Moneesh Upmanyu
The relaxation of twist in elastic filaments often drives conformational changes. We explore this paradigm using all-atom computations and report the formation of novel supercoiled…
Dynamical stability in scalar-tensor cosmology
H. Farajollahi, A. Shahabi, A. Salehi
We study FRW cosmology for a double scalar - tensor theory of gravity where two scalar fields are nonminimally coupled to the geometry. In a framework to study stability and attrac…
Observational constraints in scalar tensor theory with tachyonic potential
H. Farajollahi, A. Salehi, A. Shahabi
We study the dynamics of the scalar tensor cosmological model in the presence of tachyon field. In an alternative approach, in two exponential and power law form of the scalar fiel…
