Negative Thermal Expansion Coefficient of Graphene Measured by Raman Spectroscopy
Duhee Yoon, Young-Woo Son, Heonsik Cheong
The thermal expansion coefficient (TEC) of single-layer graphene is estimated with temperature-dependent Raman spectroscopy in the temperature range between 200 and 400 K. It is fo…
Stability of Localized Integral Operators on Weighted spaces
Kyung Soo Rim, Chang Eon Shin, Qiyu Sun
In this paper, we consider localized integral operators whose kernels have mild singularity near the diagonal and certain Holder regularity and decay off the diagonal. Our model ex…
Molecular Dynamics Simulation Study of Nonconcatenated Ring Polymers in a Melt: II. Dynamics
Jonathan D. Halverson, Won Bo Lee, Gary S. Grest +2
Molecular dynamics simulations were conducted to investigate the dynamic properties of melts of nonconcatenated ring polymers and compared to melts of linear polymers. The longest…
Molecular Dynamics Simulation Study of Nonconcatenated Ring Polymers in a Melt: I. Statics
Jonathan D. Halverson, Won Bo Lee, Gary S. Grest +2
Molecular dynamics simulations were conducted to investigate the structural properties of melts of nonconcatenated ring polymers and compared to melts of linear polymers. The longe…
Ternary codes associated with symplectic groups and power moments of Kloosterman sums with square arguments
Dae San Kim, Ji Hyun Kim
In this paper, we construct two ternary linear codes associated with the symplectic groups Sp(2,q) and Sp(4,q). Here q is a power of three. Then we obtain recursive formulas for th…
Correlation function of dyonic strings
Xiaojian Bai, Bum-Hoon Lee, Chanyong Park
We investigate the two- and three-point correlation functions of the dyonic magnon and spike, which correspond to the solitonic string moving in the Poincare AdS and three-dimensio…
