量子效应能把DNA凝聚体结合在一起吗?
Do quantum effects hold together DNA condensates?
摘要:
本文重新考虑了水中存在抗衡离子时DNA分子间的静电相互作用,并提出它服从一个修正的Poisson-Boltzmann方程。量子涨落,然后研究和显示,导致真空相互作用,数值计算的几种配置的许多DNA链,并发现是强烈的多体。这种Casimir真空相互作用可以是将DNA分子聚集在一起的“胶水”。
英文摘要:
The classical electrostatic interaction between DNA molecules in water in the presence of counterions is reconsidered and we propose it is governed by a modified Poisson-Boltzmann equation. Quantum fluctuations are then studied and shown to lead to a vacuum interaction that is numerically computed for several configurations of many DNA strands and found to be strongly many-body. This Casimir vacuum interaction can be the ``glue'' holding together DNA molecules into aggregates.
