Class Notes

GEN ST 297

Professor Li, Chemistry

  • Quantum computing - what does chemistry have to do with it?
  • Adjunct position in material science, but bread and butter is CS tools to study chemical phenomena.
  • Develop algorithms to simulate chmemical properties - dance of electrons to represent quantum entanglement.

What do Electrons Look Like in Molecules?

  • Electron Structure Theory - from atom to molecule.
  • Electrons can take on many different shapes - the nucleus can take on different shapes as well.
  • A quantum particle - no longer dots in space.
  • We cannot develop quantum information from the notion of two dots in space.
  • In the quantum world, these have wave functions that extend far away from the center.
  • Two spheres have wave functions in which the tails can ‘talk’ or ‘communicate’ to one another.
  • Quantum entanglement - commmunication, dots are no longer dots but clouds.
  • You can mathematically prove this from the wave function.
  • However, it is very difficult to observe entanglement unless we create much larger waves.
  • Foundations of quantum computing and entanglement.
  • If we have two electrons that can talk to one another in a molecule, they can form a more extended network - short-distance entanglement, molecular orbitals.

Electron Dynamics and Spectroscopy

  • Fields can facilitate electron communication within a molecule.
  • In the quantum world, electrons even very far from one another can communicate via electromagnetic fields.
  • Quantum mechanics is a series of hypotheses.
  • You always have nonzero probabilities that two electrons can communicate with one another.
  • Qubit nuclear entanglement.

Time-Dependent Quantum Theory for Modeling Electron Dynamics in Molecules

  • Perform Fourier transformation on entanglement.
  • Everything in the end is mathematics - while quantum mechanics is not derived from mathematics, we can use mathematics to understand quantum mehcnaics.

Computational Chemistry

  • Fortran, C++, Python, etc.
  • Can use code to simulate quantum mechanical behavior.
  • Use computing facilities to understand entanglement of many bodies.
  • We can understand material properties; if we know an electronic system can behave in a certain way, we can design new molecules and materials.

Professor Million, American Indian Studies

  • Fighting for the presence of an Indian Studies Department in many places, including on the University of Washington.
  • Many people don’t know who American Indian peoples are.
  • Indian was a word brought by Europeans, designated “Indians”.
  • There is a real history to designations - it is a political history that goes into it.
  • 500 federally recognized Native nations in the United States.
  • In the United States, Native states have the same powers as the state of Washington; the state must negotiate with Native peoples.
  • Federal recognition and tribes in Washington
  • AI department turned 50 last year!
  • Interdisciplinary study.
  • Residential Schools - removing culture in a brutal fashion.

“There is no history that has not been fought into truth.”

  • Every generation argues the truth all over again.
  • AIS 170 - Art and Aesthetics

Research and Internships

Undergraduate Research

  • A creative and systematic process of discovering new knowledge.
  • UW is a research institution.
  • Take persistence and applying to research.
  • Many aspects of the research process can be performed remotely.

Finding Internships

  • Career and internship center.
  • Internship - way to integrate academic learning with hands-on experience.
  • Develop or refine skills
  • Explore sectors, careers, and environments.
  • Pay, credit, none, or both.
  • Typically lasts at least 1 quarter - year-round or summer.
  • Internships are different.
  • Internship - intentional focus on student learning.
  • Have a defined beginning and end.
  • Often center around defined projects.
