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?

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]
classical thermodynamics

Cardinal Principles of Behavior –The Science of Matter Beyond Equilibrium

Classical Thermodynamics…

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
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?

  • Extreme environments (ultrahigh pressure and
  • shock waves, extreme radiation, plasmas…)
