International Team Solves Mystery of Colloidal Chains
International Team Mystery of Colloidal
2017/7/20
When Northwestern Engineering’s Erik Luijten met Zbigniew Rozynek, they immediately became united by a mystery.Presenting at a conference in Norway, Rozynek, a researcher at Adam Mickiewicz University...
The thermodynamics of Kaluza–Klein black hole/bubble chains
Bubble surface black holes time and space exchange said sex black hole static
2014/12/19
A Killing bubble is a minimal surface that arises as the fixed surface of a spacelike Killing field. We compute the bubble contributions to the Smarr relations and the mass and tension first laws for ...

Monte Carlo simulation phase coexistence Gibbs ensemble molecular simulation multi-component system
2012/4/24
In Monte Carlo simulations, the thermal equilibria quantities are estimated by ensemble average over a sample set containing a large number of correlated samples. As the stochastic error of the simula...
A molecular simulation analysis of producing monatomic carbon chains by stretching ultranarrow graphene nanoribbons
molecular simulation analysis monatomic carbon chains ultranarrow graphene nanoribbons Computational Physics
2012/4/20
Atomistic simulations were utilized to develop fundamental insights regarding the elongation process starting from ultranarrow graphene nanoribbons (GNRs) and resulting in monatomic carbon chains (MAC...
