A typical feature of spontaneous collapse models which aim at localizing wavefunctions in space is the violation of the principle of energy conservation. In the models proposed in the literature, the stochastic field which is responsible for the localization mechanism causes the momentum to behave like a Brownian motion, whose larger and larger fluctuations show up as a steady increase of the energy of the system. In spite of the fact that, in all situations, such an increase is small and… 

Some Comments on the Formal Structure of Spontaneous Localization Theories

We propose a mathematical and a conceptual framework that encompasses and generalizes the “flash” ontology discussed in a recent paper by R. Tumulka.

Dissipative collapse models with nonwhite noises

We study the generalization of the QMUPL model which accounts both for memory and dissipative effects. This is the first model where both features are combined. After having derived the non-local

The tension between the value of the Hubble constant $$H_0$$ H 0 determined from local supernovae data and the one inferred from the cosmic microwave background based on the $$\Lambda $$ Λ CDM

Diffusion in unimodular gravity: Analytical solutions, late-time acceleration, and cosmological constraints

Unimodular gravity is an appealing approach to address the cosmological constant problem. In this scenario, the vacuum energy density of quantum fields does not gravitate and the cosmological

Non-Markov Processes in Quantum Theory

TLDR
Basic notions in the framework of open quantum systems are introduced, stressing in particular analogies and differences with models used for introducing modifications of quantum mechanics which should help in dealing with the measurement problem.
