Summary
We modeled photon-plasmon interactions at a plasmonic slit using a quantum tritter. Interference pattern visibility precisely quantifies the coupling phase shift, crucial for quantum plasmonics and classical optics.
Area of Science:
- Quantum optics
- Plasmonics
- Quantum theory
Background:
- Scattering processes are fundamental to quantum theory.
- Scattering phase shifts reveal complex light-matter interactions in optics.
Purpose of the Study:
- Investigate the phase shift of a single photon scattering into a surface plasmon polariton.
- Characterize photon-plasmon interactions at a plasmonic slit for quantum plasmonic experiments.
Main Methods:
- Modeling the photon-plasmon interaction using a quantum-mechanical tritter (a six-port scattering element).
- Analyzing interference pattern visibilities (double-slit and triple-slit) as observables.
Main Results:
- Demonstrated that interference pattern visibilities can determine the coupling phase shift.
- Validated the quantum tritter model through simulations and experiments.
Conclusions:
- The developed model accurately describes photon-plasmon interaction at plasmonic slits.
- This work has implications for quantum plasmonic interference and classical optical applications.

02:39Phase Diagrams
49.9K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

01:20Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
1.6K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

01:22Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)
1.5K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

02:31Phase Transitions
22.8K
Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

01:21G-protein Coupled Receptors
131.7K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

01:17Spin–Spin Coupling: One-Bond Coupling
1.4K
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...
