9th International Conference DICE2018 Spacetime - Matter - Quantum Mechanics
Submitted by
JMiszczak on Fri, 16/03/2018 - 10:48.
Following DICE2002 - DICE2016, this biannual workshop addresses
researchers in the fields of fundamental interactions, cosmology,
general relativity, and quantum mechanics:
The pillars of modern physics, quantum mechanics and general
relativity, coexist very successfully, having in their respective
domains impressive observational support. However, questionable
unification of the known forces, cosmological constant problems, black
hole entropy puzzle, and conceptual difficulties of quantum mechanics
and its application to the Universe are stumbling blocks on the way to a
deeper understanding.
Attempts to quantize gravity continue to stimulate studies of
classical and quantum dynamics and of statistical properties of
"timeless" reparametrization-invariant systems. A central problem is to
determine observables consistent with the constraints. New ideas attract
attention that consider spacetime or gravity as emergent phenomena, much
like hydrodynamics is seen to arise from atomic physics. Even quantum
mechanics might reflect dynamics beneath, which is hidden by the
coarse-graining to scales where quantum theory has been tested
successfully, nineteen orders of magnitude away from the Planck
scale.
Classical behavior in complex quantum systems, attributed to
decoherence, has recently been studied from atomic to mesoscopic
systems, the motivation being largely the quest for quantum information
processing. However, decohering degrees of freedom in subatomic and
general relativistic systems are little understood. The control of
quantum systems by classical means and the study of quantum-classical
hybrid dynamics present new challenges of practical as well as of
fundamental character. The related measurement problem, wave function
collapse or objective reduction persist as unresolved issues.
The study of these topics may include an analysis of the kind of
information that exists in systems with many degrees of freedom and
typically long-range interactions and of the basic conditions under
which it can be extracted. Corresponding measures of complexity have
been elaborated and could play a role here.
Topics for DICE2018 are defined but not constrained by overlapping
interests in:
- emergent spacetime, matter, and symmetries
- quantum coherence from micro- to macroscopic
- new key experiments
- quantum mechanics interfacing with gravity
- quantum gravity / cosmology and high-energy physics
