Is Gravity an Entropic Force?
The remarkable connections between gravity and thermodynamics seem to imply that gravity is not fundamental but emergent, and in particular, as Verlinde suggested, gravity is probably an entropic force. In this paper, we will argue that the idea of gravity as an entropic force is debatable. It is shown that there is no convincing analogy between gravity and entropic force in Verlinde’s example....
متن کاملIs Gravity Entropic Force?
If we assume that the source of thermodynamic system, ρ and p, are also the source of gravity, then either thermal quantities, such as entropy, temperature, and chemical potential, can induce gravitational effects, or gravity can induce thermal effects. We find that gravity can be seen as entropic force only for systems with constant temperature and zero chemical potential. The case for Newtoni...
متن کاملEntropic force between membranes reexamined.
L ipid bilayers serve as model surfaces that are often used to understand the behavior of actual cell membranes. Cell adhesion (1, 2), membrane fusion (1), binding-unbinding transition (3), self-assembly, and related phenomena govern an astounding array of biological functions; for example, sperm-egg fusion is the basis of mammalian reproducion (1). These phenomena are dictated by a complex int...
متن کاملCoulomb Force Virtual Space Structures
Recently, several uses for intercraft Coulomb forces have been explored. Proposed applications have ranged from creating static formations of many spacecraft to steerable nanosat deployment systems. This paper considers the use of Coulomb forces for creating space structures. Unlike conventional space structures, these ”virtual space structures” have no physical connections. Instead, they are h...
متن کاملHopping around an entropic barrier created by force.
We use Langevin dynamics to investigate the role played by the recently discovered force-induced entropic energy barrier on the two-state hopping phenomena that has been observed in single RNA, DNA and protein molecules placed under a stretching force. Simple considerations about the free energy of a molecule readily show that the application of force introduces an entropic barrier separating t...
