The Bohr Model02:18

The Bohr Model

50.6K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as...

Deactivation Processes: Jablonski Diagram

Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

Crystal Field Theory
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...

Fermi Level Dynamics01:12

Fermi Level Dynamics

The vacuum level denotes the energy threshold required for an electron to escape from a material surface. It is usually positioned above the conduction band of a semiconductor and acts as a benchmark for comparing electron energies within various materials.
Electron affinity in semiconductors refers to the energy gap between the minimum of its conduction band and the vacuum level and it is a critical parameter in determining how easily a semiconductor can accept additional electrons.

Area of Science:

  • Condensed matter physics
  • Quantum many-body systems
  • Synthetic quantum materials

Background:

  • Flat bands in condensed matter systems enable emergent states like insulators and fractionalized excitations.
  • Aharonov-Bohm caging is a phenomenon where particles localize due to destructive interference in flat-band systems.

Purpose of the Study:

  • To experimentally realize and control tunable flat-band models using strongly interacting Rydberg atoms.
  • To investigate the dynamics of Aharonov-Bohm caging in engineered rhombic lattices with twisted boundaries.
  • To explore the influence of tunable gauge fields and inter-particle interactions on emergent phenomena.

Main Methods:

  • Utilized synthetic dimensions to engineer a flat-band rhombic lattice with twisted boundaries.
  • Employed strongly interacting Rydberg atoms as the quantum system.
  • Applied a tunable gauge field to control Aharonov-Bohm caging dynamics.
  • Performed microscopic measurements of Rydberg pairs to probe interactions and localization.

Main Results:

  • Observed the breakdown of Aharonov-Bohm caging in the strong dipolar interaction regime due to lattice band mixing.
  • Demonstrated the persistence of Aharonov-Bohm caging in the weak interaction regime.
  • Observed emergent effective magnetism arising from the mixing of degenerate flat-band states in the weak interaction limit.

Conclusions:

  • Strong interactions drive the breakdown of Aharonov-Bohm caging, while weak interactions allow its persistence and lead to emergent magnetism.
  • Engineered Rydberg atom systems provide a tunable platform for studying quantum many-body physics and emergent phenomena in synthetic quantum materials.
  • The findings offer insights into the control of localization and emergent states in engineered lattice systems.
