Trace dynamics and its implications for my work of the last two decades
Stephen L. Adler
I review the basic ideas of "trace dynamics", as formulated in my 2004 Cambridge University Press book "Quantum Theory as an Emergent Phenomenon", and then discuss how they have in…
Minimum measurement time: lower bound on the frequency cutoff for collapse models
Stephen L. Adler, Angelo Bassi, Luca Ferialdi
The CSL model predicts a progressive breakdown of the quantum superposition principle, with a noise randomly driving the state of the system towards a localized one, thus accountin…
The Continuous Spontaneous Localization Layering Effect from a Lattice Perspective
Stephen L. Adler, Angelo Bassi, Matteo Carlesso
For a solid lattice, we rederive the Continuous Spontaneous Localization (CSL) noise total energy gain of a test mass starting from a Lindblad formulation, and from a similar start…
Testing Continuous Spontaneous Localization with Fermi liquids
Stephen L. Adler, Angelo Bassi, Matteo Carlesso +1
Collapse models describe phenomenologically the quantum-to-classical transition by adding suitable nonlinear and stochastic terms to the Schroedinger equation, thus (slightly) modi…
Connecting the dots: Mott for emulsions, collapse models, colored noise, frame dependence of measurements, evasion of the "Free Will Theorem"
Stephen L. Adler
We review the argument that latent image formation is a measurement in which the state vector collapses, requiring an enhanced noise parameter in objective reduction models. Tentat…
Heating Through Phonon Excitation Implied by Collapse Models
Stephen L. Adler
We calculate the rate of heating through phonon excitation implied by the noise postulated in mass-proportional-coupled collapse models, for a general noise power spectrum. For whi…
Minimum Interior Temperature for Solid Objects Implied by Collapse Models
Stephen L. Adler
Heating induced by the noise postulated in wave function collapse models leads to a lower bound to the temperature of solid objects. For the noise parameter values $λ={\rm coupling…
Bulk Heating Effects as Tests for Collapse Models
Stephen L. Adler, Andrea Vinante
We discuss limits on the noise strength parameter in mass-proportional-coupled wave function collapse models implied by bulk heating effects, and examine the role of the noise powe…
Does the Peres experiment using photons test for hyper-complex (quaternionic) quantum theories?
Stephen L. Adler
Assuming the standard axioms for quaternionic quantum theory and a spatially localized scattering interaction, the -matrix in quaternionic quantum theory is complex valued, not…
Gravitational Decoherence for Mesoscopic Systems
Stephen L. Adler, Angelo Bassi
We extend the recent gravitational decoherence analysis of Pikovski et al. to an individual mesoscopic system with internal state characterized by a coherent superposition of energ…
Where is quantum theory headed?
Stephen L. Adler
Public talk at the EmQM13 conference opening event on "The Future of Quantum Mechanics"
On spontaneous photon emission in collapse models
Stephen L. Adler, Angelo Bassi, Sandro Donadi
We reanalyze the problem of spontaneous photon emission in collapse models. We show that the extra term found by Bassi and Duerr is present for non-white (colored) noise, but its c…
Quantum Theory: Exact or Approximate?
Stephen L. Adler, Angelo Bassi
Quantum mechanics has enjoyed a multitude of successes since its formulation in the early twentieth century. At the same time, it has generated puzzles that persist to this day. Th…
Collapse models with non-white noises II: particle-density coupled noises
Stephen L. Adler, Angelo Bassi
We continue the analysis of models of spontaneous wave function collapse with stochastic dynamics driven by non-white Gaussian noise. We specialize to a model in which a classical…
Collapse models with non-white noises
Stephen L. Adler, Angelo Bassi
We set up a general formalism for models of spontaneous wave function collapse with dynamics represented by a stochastic differential equation driven by general Gaussian noises, no…
Photon emission rate from atomic systems in the CSL model
Stephen L. Adler, Fethi M. Ramazanoglu
We calculate the photon emission rate from a general atomic system in the mass- proportional CSL model. For an isolated charged particle emitting kilovolt gamma rays, our results a…
A density tensor hierarchy for open system dynamics: retrieving the noise
Stephen L. Adler
We introduce a density tensor hierarchy for open system dynamics, that recovers information about fluctuations lost in passing to the reduced density matrix. For the case of fluctu…
Comments on Proposed Gravitational Modifications of Schrodinger Dynamics and their Experimental Implications
Stephen L. Adler
We discuss aspects of gravitational modifications of Schrodinger dynamics proposed by Diosi and Penrose. We consider first the Diosi-Penrose criterion for gravitationally induced s…
Normalization of Collisional Decoherence: Squaring the Delta Function, and an Independent Cross-Check
Stephen L. Adler
We show that when the Hornberger--Sipe calculation of collisional decoherence is carried out with the squared delta function a delta of energy instead of a delta of the absolute va…
Lower and Upper Bounds on CSL Parameters from Latent Image Formation and IGM Heating
Stephen L. Adler
We study lower and upper bounds on the parameters for stochastic state vector reduction, focusing on the mass-proportional continuous spontaneous localization (CSL) model. We show…
Notes on the Conway-Kochen Twin Argument
Stephen L. Adler
This is a revision of my original posting, in which I raised objections to part of the Conway-Kochen argument. I now agree with them that their recent reply answers my original con…
Stochastic Collapse and Decoherence of a Non-Dissipative Forced Harmonic Oscillator
Stephen L. Adler
Careful monitoring of harmonically bound (or as a limiting case, free) masses is the basis of current and future gravitational wave detectors, and of nanomechanical devices designe…
Towards Quantum Superpositions of a Mirror: an Exact Open Systems Analysis - Calculational Details
S. L. Adler, A. Bassi, E. Ippoliti
We give details of calculations analyzing the proposed mirror superposition experiment of Marshall, Simon, Penrose, and Bouwmeester within different stochastic models for state vec…
Weisskopf-Wigner Decay Theory for the Energy-Driven Stochastic Schrödinger Equation
Stephen L. Adler
We generalize the Weisskopf-Wigner theory for the line shape and transition rates of decaying states to the case of the energy-driven stochastic Schrödinger equation that has been…
