Critical review of prevailing explanations for the emergence of classicality in cosmology
Javier Berjon, Elias Okon, Daniel Sudarsky
There have been recent attempts at justifying, from first principles, and within the standard framework, the emergence of classical behavior in the post-inflationary cosmological c…
Can the quantum vacuum fluctuations really solve the cosmological constant problem?
Gabriel R. Bengochea, Gabriel León, Elias Okon +1
Recently it has been argued that a correct reading of the quantum fluctuations of the vacuum could lead to a solution to the cosmological constant problem. In this work we critical…
Expectation of primordial gravity waves generated during inflation
Gabriel León, Abhishek Majhi, Elias Okon +1
The inflationary paradigm is extremely successful regarding predictions of temperature anisotropies in the CMB. However, inflation also makes predictions for a CMB B-mode polarizat…
Losing stuff down a black hole
Elias Okon, Daniel Sudarsky
Over the years, the so-called black hole information loss paradox has generated an amazingly diverse set of (often radical) proposals. However, forty years after the introduction o…
Reassessing the link between B-modes and inflation
Gabriel León, Abhishek Majhi, Elias Okon +1
We reevaluate the predictions of inflation regarding primordial gravity waves, which should appear as B-modes in the CMB, in light of the fact that the standard inflationary paradi…
A (not so?) novel explanation for the very special initial state of the universe
Elias Okon, Daniel Sudarsky
We put forward a proposal that combines objective collapse models, developed in connection with quantum-foundational questions, with the so-called Weyl curvature hypothesis, introd…
Less Decoherence and More Coherence in Quantum Gravity, Inflationary Cosmology and Elsewhere
E. Okon, D. Sudarsky
In Crull (2015) it is argued that, in order to confront outstanding problems in cosmology and quantum gravity, interpretational aspects of quantum theory can by bypassed because de…
Can gravity account for the emergence of classicality?
Yuri Bonder, Elias Okon, Daniel Sudarsky
A recent debate has ensued over the claim by Pikovski et al. [Nat. Phys. 11, 668 (2015)] that systems with internal degrees of freedom undergo a universal, gravity-induced, type of…
Comment on "Universal decoherence due to gravitational time dilation"
Yuri Bonder, Elias Okon, Daniel Sudarsky
We present a series of arguments against the results of the paper "Universal decoherence due to gravitational time dilation" by Pikovski et al. (arXiv:1311.1095).
The Consistent Histories Formalism and the Measurement Problem
E. Okon, D. Sudarsky
In response to a recent rebuttal of [1] presented in [2], we defend the claim that the Consistent Histories formulation of quantum mechanics does not solve the measurement problem.…
The Black Hole Information Paradox and the Collapse of the Wave Function
E. Okon, D. Sudarsky
The black hole information paradox arises from an apparent conflict between the Hawking black hole radiation and the fact that time evolution in quantum mechanics is unitary. The t…
Benefits of Objective Collapse Models for Cosmology and Quantum Gravity
Elias Okon, Daniel Sudarsky
We display a number of advantages of objective collapse theories for the resolution of long-standing problems in cosmology and quantum gravity. In particular, we examine applicatio…
Measurements according to Consistent Histories
Elias Okon, Daniel Sudarsky
We critically evaluate the treatment of the notion of measurement in the Consistent Histories approach to quantum mechanics. We find such a treatment unsatisfactory because it reli…
Position Operators and Center of Mass: New Perspectives
Pedro Aguilar, Chryssomalis Chryssomalakos, Hector Hernandez Coronado +1
After reviewing the work of Pryce on Center-of-Mass (CoM) definitions in special relativity, and that of Jordan and Mukunda on position operators for relativistic particles with sp…
Quantum equivalence principle without mass superselection
H. Hernandez-Coronado, E. Okon
The standard argument for the validity of Einstein's equivalence principle in a non-relativistic quantum context involves the application of a mass superselection rule. It is surpr…
On the Consistency of the Consistent Histories Approach to Quantum Mechanics
Elias Okon, Daniel Sudarsky
The Consistent Histories (CH) formalism aims at a quantum mechanical framework which could be applied even to the universe as a whole. CH stresses the importance of histories for q…
