从CMBR的形成和标准宇宙学看量子力学自发坍缩模型的界限

Bounds on Spontaneous Collapse model of Quantum Mechanics from formation of CMBR and Standard Cosmology

量子力学的连续自发局域化（CSL）模型通过加入非线性随机项来修正薛定谔方程，使得系统的总能量以与坍缩率$λ$成正比的恒定速率增加。因此，将CSL模型应用于宇宙学情景可以改变粒子在演化过程中的热行为，我们将通过考虑几种宇宙学情景对$λ$施加约束。

Prediction in Quantum Cosmology

Lectures by the author at the 1986 Cargese summer school modestly corrected and uploaded for greater accessibility. Some of the author's views on the quantum mechanics of cosmology have changed from those presented here but may still be of historical interest. The material on the Born-Oppenheimer approximation for solving the Wheeler-DeWitt equation and the work on the classical geometry limit and the approximation of quantum field theory in curved spacetime are still of interest and of use.

引力、熵与宇宙学：寻求清晰

Gravity, Entropy, and Cosmology: In Search of Clarity

我讨论引力系统的统计力学，特别是它的宇宙学意义，并认为，在统计力学的基础上，许多关于这个问题的传统观点体现了重大的混乱，我试图提供一个更清晰和更准确的帐户。特别是，我观察到（i）引力\emph{in}熵计算的作用必须与熵\emph{of}引力区分开来，（ii）虽然引力坍缩是熵增加的，但这通常不是因为坍缩物质本身的熵增加，（iii）热力学第二定律的有效性并不归功于引力坍缩的统计力学。

Collapse models and cosmology

Attempts to apply quantum collapse theories to Cosmology and cosmic inflation are reviewed. These attempts are motivated by the fact that the theory of cosmological perturbations of quantum-mechanical origin suffers from the single outcome problem, which is a modern incarnation of the quantum measurement problem, and that collapse models can provide a solution to these issues. Since inflationary predictions can be very accurately tested by cosmological data, this also leads to constraints on collapse models. These constraints are derived in the case of Continuous Spontaneous Localization (CSL)…

Exact Classical Correspondence in Quantum Cosmology

We find a Friedmann model with appropriate matter/energy density such that the solution of the Wheeler-DeWitt equation exactly corresponds to the classical evolution. The well-known problems in quantum cosmology disappear in the resulting coasting evolution. The exact quantum-classical correspondence is demonstrated with the help of the de Broglie-Bohm and modified de Broglie-Bohm approaches to quantum mechanics. It is reassuring that such a solution leads to a robust model for the universe, which agrees well with cosmological expansion indicated by SNe Ia data.

Cosmology with a Decaying Vacuum Energy Parametrization Derived from Quantum Mechanics

Within the quantum mechanical treatment of the decay problem one finds that at late times $t$ the survival probability of an unstable state cannot have the form of an exponentially decreasing function of time $t$ but it has an inverse power-like form. This is a general property of unstable states following from basic principles of quantum theory. The consequence of this property is that in the case of false vacuum states the cosmological constant becomes dependent on time: $Λ- Λ_{\text{bare}}\equiv Λ(t) -Λ_{\text{bare}} \sim 1/t^{2}$. We construct the cosmological model with decaying vacuum en…
