标题： One-loop quantum corrections to cosmological scalar field potentials

摘要： 我们研究用于解释暗能量、暗物质或暗流体的复数或耦合实标量场的势的环修正。 我们表明，SUGRA快子和暗物质标量场势在量子涨落下是稳定的，并我们提出了耦合快子和暗流体标量场势不稳定性解决方案。 我们还发现，与费米子的耦合非常受限，除非这种耦合具有已存在于标量场势中的结构，或者可以通过高阶修正来补偿。 最后，我们研究了曲率和动能项修正的影响。 显示英文摘要

摘要： We study the loop corrections to potentials of complex or coupled real scalar fields used in cosmology to account for dark energy, dark matter or dark fluid. We show that the SUGRA quintessence and dark matter scalar field potentials are stable against the quantum fluctuations, and we propose solutions to the instability of the potentials of coupled quintessence and dark fluid scalar fields. We also find that a coupling to fermions is very restricted, unless this coupling has a structure which already exists in the scalar field potential or which can be compensated by higher order corrections. Finally, we study the influence of the curvature and kinetic term corrections.
