Chlorine Adsorption on Graphene: Chlorographene
Hasan Sahin, Salim Ciraci
We perform first-principles structure optimization, phonon frequency and finite temperature molecular dynamics calculations based on density functional theory to study the interact…
Self-assembly mechanisms of short atomic chains on single layer graphene and boron nitride
V. Ongun Özçelik, S. Ciraci
Nucleation and growth mechanisms of short chains of carbon atoms on single-layer, hexagonal boron nitride (h-BN), and short BN chains on graphene are investigated using first-princ…
Robust Ground State and Artificial Gauge in DQW Exciton Condensates under Weak Magnetic Field
T. Hakioğlu, Ege Özgün, Mehmet Günay
Exciton condensate is a vast playground in studying a number of symmetries that are of high interest in the recent developments in topological condensed matter physics. In DQWs the…
Building User-defined Runtime Adaptation Routines for Stream Processing Applications
Gabriela Jacques-Silva, Buğra Gedik, Rohit Wagle +2
Stream processing applications are deployed as continuous queries that run from the time of their submission until their cancellation. This deployment mode limits developers who ne…
Current Response in Extended Systems as a Geometric Phase: Application to Variational Wavefunctions
Balázs Hetényi
The linear response theory for current is investigated in a variational context. Expressions are derived for the Drude and superfluid weights for general variational wavefunctions.…
Relative group cohomology and the orbit category
Semra Pamuk, Ergun Yalcin
Let be a finite group and $\cF$ be a family of subgroups of closed under conjugation and taking subgroups. We consider the question whether there exists a periodic relative…
