Nucleation of vacuum bubbles in Brans-Dicke type theory
Hongsu Kim, Bum-Hoon Lee, Wonwoo Lee +2
In this paper, we explore the nucleation of vacuum bubbles in the Brans-Dicke type theory of gravity. In the Euclidean signature, we evaluate the fields at the vacuum bubbles as so…
Electrical transport in small bundles of single-walled carbon nanotubes: intertube interaction and effects of tube deformation
Taekyung Kim, Gunn Kim, Woon Ih Choi +2
We report a combined electronic transport and structural characterization study of small carbon nanotube bundles in field-effect transistors (FET). The atomic structures of the bun…
Band gap control of small bundles of carbon nanotubes using applied electric fields: A density functional theory study
Gunn Kim, J. Bernholc, Young-Kyun Kwon
Electrostatic screening between carbon nanotubes (CNTs) in a small CNT bundle leads to a switching behavior induced by electric field perpendicular to the bundle axis. Using a firs…
Generation of a bubble universe using a negative energy bath
Dong-il Hwang, Dong-han Yeom
This paper suggests a model for a bubble universe using buildable false vacuum bubbles. We study the causal structures of collapsing false vacuum bubbles using double-null simulati…
The dynamically induced Fermi arcs and Fermi pockets in two dimensions: a model for underdoped cuprates
Han-Yong Choi, Seung Hwan Hong
We investigate the effects of the dynamic bosonic fluctuations on the Fermi surface reconstruction in two dimensions as a model for the underdoped cuprates. At energies larger than…
Tunable charge donation and spin polarization of metal adsorbates on graphene using applied electric field
Jae-Hyeon Parq, Jaejun Yu, Young-Kyun Kwon +1
Metal atoms on graphene, when ionized, can act as a point charge impurity to probe a charge response of graphene with the Dirac cone band structure. To understand the microscopic p…
