Events in quantum mechanics are maximally non-absolute [PDF]
Quantum, 2022 The notorious quantum measurement problem brings out the difficulty to reconcile two quantum postulates: the unitary evolution of closed quantum systems and the wave-function collapse after a measurement.

Quantum-collapse Bell inequalities [PDF]
Physical Review A, 2014 We propose Bell inequalities for discrete or continuous quantum systems which test the compatibility of quantum physics with an interpretation in terms of deterministic hidden-variable theories. The wave function collapse that occurs in a sequence of quantum measurements enters the upper bound via the concept of quantum conditional probabilities.

Quantum black holes from quantum collapse [PDF]
Physical Review D, 2001 The Schwarzschild black hole can be viewed as the special case of the marginally bound Lema\^ıtre-Tolman-Bondi models of dust collapse which corresponds to a constant mass function. We have presented a midi-superspace quantization of this model for an arbitrary mass-function in a separate publication.

Journal of High Energy Physics, 2022 Using the braid group topological approach to quantum statistics we demonstrate that for strong gravitational field occurring in neutron star merger with mass exceeding the Tolman, Oppenheimer and Volkoff limit the quantum statistics of particles beneath

Dynamics of quantum collapse in energy measurements [PDF]
Physical Review A, 1995 The influence of continuous measurements of energy with a finite accuracy is studied in various quantum systems through a restriction of the Feynman path-integrals around the measurement result. The method, which is equivalent to consider an effective Schrödinger equation with a non-Hermitian Hamiltonian, allows one to study the dynamics of the ...

Singular Mean-Field States: A Brief Review of Recent Results
Condensed Matter, 2020 This article provides a focused review of recent findings which demonstrate, in some cases quite counter-intuitively, the existence of bound states with a singularity of the density pattern at the center; the states are physically meaningful because ...

Gravitational Collapse in Quantum Einstein Gravity [PDF]
Foundations of Physics, 2018 The existence of spacetime singularities is one of the biggest problems of nowadays physics. According to Penrose, each physical singularity should be covered by a "cosmic censor" which prevents any external observer from perceiving their existence.

Collapse dynamics and Hilbert-space stochastic processes
Scientific Reports, 2021 Spontaneous collapse models of state vector reduction represent a possible solution to the quantum measurement problem. In the present paper we focus our attention on the Ghirardi–Rimini–Weber (GRW) theory and the corresponding continuous localisation ...

Quantum vacuum effects on the formation of black holes
Journal of High Energy Physics, 2023 We study the backreaction of quantum fields induced through the vacuum polarization and the conformal anomaly on the collapse of a thin shell of dust. It is shown that the final fate of the collapse process depends on the physical properties of the shell,
