Molecules Cardinal Principles of Behavior -

Creating a New Language for Electronic Structure
- Real-Time Dynamics of Electrons in Atoms and
Molecules
1. How and why does the adiabatic separation of
electrons and nuclei fail utterly? - What are
the manifestations in photodynamics? - Other
experimental handles? 2. How do electrons
actually move in atoms and in molecules? -
Reality of arrows mechanisms of reactions? -
Correlated or single-particle evolution? 3. How
does atomic and molecular matter respond to very
short (attosecond) and very strong ( terawatt )
excitation? - Collective behaviors? - Mixed
plasmons? 4. Can we control the motions of the
interatomic electrons, driving processes in a
desired direction? Specific projects/goals

Creating a New Language for Electronic Structure
Real-Time Dynamics of Electrons in Atoms and
Molecules
BESAC Subcommittee Science Grand Challenges
Walter Kohn The dynamics of interacting finite mass nuclei and electrons, far outside the Born-Oppenheimer approximation, caused by high energy and high frequency incident radiation and particles.
Mark Ratner What are electrons doing in molecules - attosecond imaging for electronic intramolecular dynamics?
Jun Ye Can we coherently control matter field interactions at ever increasing energy scales?
Bob Silbey Create an ultra-fast,
coherent X- Ray Laser User Facility
that will support a large number of
users. Cherry Murray Can we control
transition states in chemical
reactions/phase transitions to create
novel compounds/materials?
18
Cardinal Principles of Behavior The Science of
Matter Beyond Equilibrium
BESAC Subcommittee Science Grand Challenges
  • When is a steady state attained? How do its
    properties differ from equilibrated states?
  • How is structure determined away from
    equilibrium? Can we characterize and understand
    metastability? Can we design metastable
    structures for specific properties and
    applications?
  • Are there variational principles, or
    thermodynamic laws, out of equilibrium?
  • Can metastable structures be advantageous in
    sustainable processes?
  • Specific projects/goals

19
Classical Thermodynamics
Cardinal Principles of Behavior The Science of
Matter Beyond Equilibrium
We need a theory of organization and dynamics of
matter beyond equilibrium
A confluence of factors - including new tools for
manipulating nanoscale systems, new theoretical
insights, and the clear need for design rules for
the construction of future classical and quantum
machines make it essential, and for the first
time, plausible, to attempt to develop a
thermodynamic formalism of matter beyond
equilibrium
But for small and/or driven systems
(nanotechnology, biology, materials science,
photovoltaics, photonics, quantum computers)
errors are significant
Errors are small when applied to steam engines

Anticipated Benefits
Cardinal Principles of Behavior Science of
Matter beyond Equilibrium
One of the key benefits of classical
thermodynamics Its ability to generate
fundamental design rules for macroscopic
machines operating near equilibrium. E.g.
Anticipated key benefit of a theory of
organization and dynamics of matter beyond
equilibrium Fundamental design rules for
classical or quantum machines of arbitrary size
and operating arbitrarily far from equilibrium

BESAC Subcommittee Science Grand Challenges
  • 1. How does the environment of a system modify
    and control its properties?
  • - Simple geometric constraint?

    self-assembly?
