5.
Seventh International Workshop
DICE2014
Organized at
Castello
Pasquini/Castiglioncello (Tuscany),
September 15-19, 2014
Titled
"Spacetime
- Matter - Quantum Mechanics"
Topic:
The pillars of modern physics,
quantum mechanics and general
relativity, coexist very
successfully, having in their
respective domains impressive
observational support. However,
black hole entropy puzzle, missing
unification of the known forces, and
conceptual problems in applying
quantum theory 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. Presently, new ideas
attract attention that consider
spacetime and/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 to be addressed include:
-
Decoherence, quantum-to-classical transition, measurement problem
-
Quantum-classical hybrids
-
Quantum coherent processes all the way ... to biology
-
Key experiments
-
Emergent spacetime, matter, and symmetries
-
Quantum gravity / cosmology and high-energy physics
