Computational Models of Stellar Collapse and Core-Collapse Supernovae
Core-collapse supernovae are among Nature’s most energetic events. They mark the end of massive star evolution and pollute the interstellar medium with the life-enabling ashes of thermonuclear burning. Despite their importance for the evolution of galaxies and life in the universe, the details of the core-collapse supernova explosion mechanism remain in the dark and pose a daunting computationa...
متن کاملappreciably constrains collapse models
LISA Pathfinder’s measurement of a relative acceleration noise between two free-falling test masses with a square root of the power spectral density of 5.2± 0.1 fm s/ √ Hz [1] appreciably constrains collapse models. In particular, we bound the localization rate parameter, λCSL, in the continuous spontaneous localization model (CSL) to be at most (2.96 ± 0.12)× 10 s. Moreover, we bound the regul...
متن کاملSimulating Causal Collapse Models
We present simulations of causal dynamical collapse models of field theories on a 1 + 1 null lattice. We use our simulations to compare and contrast two possible interpretations of the models, one in which the field values are real and the other in which the state vector is real. We suggest that a procedure of coarse graining and renormalising the fundamental field can overcome its noisiness an...
متن کاملTrue Collapse and False Collapse
We emphasize that standard quantum theory (SQT) is incomplete because it doesn’t describe what is experimentally observed, namely events, nor does it satisfactorily define the circumstances under which events may occur. Simple models are given (all of which have the same density matrix evolution) to illustrate schemes which claim to complete SQT. It is shown how the model based upon the Continu...
متن کاملCollapse models: analysis of the free particle dynamics
We study a model of spontaneous wavefunction collapse for a free quantum particle. We analyze in detail the time evolution of the single–Gaussian solution and the double–Gaussian solution, showing how the reduction mechanism induces the localization of the wavefunction in space; we also study the asymptotic behavior of the general solution. With an appropriate choice for the parameter λ which s...
