Summary
We developed a quantum optical theory for surface lattice resonances (SLRs) in nanoparticle arrays. This framework describes interactions with quantum emitters and nonlinear material effects, enabling new experimental possibilities.
Area of Science:
- Quantum optics
- Plasmonics
- Nanophotonics
Background:
- Surface lattice resonances (SLRs) are high-Q in-plane diffractive modes in periodic nanoparticle arrays.
- Existing theories primarily use classical electrodynamics and linear response, lacking quantum descriptions for nonlinearities.
Purpose of the Study:
- To derive a quantum optical theory for nanoparticle lattices and surface lattice resonances.
- To model interactions with quantum emitters and material nonlinearities beyond simplified approximations.
Main Methods:
- Quantum input-output relations derived within the electric dipole approximation.
- Analysis of coupling between nanoparticle arrays and external quantum emitters.
- Extension to molecular optomechanics and arrays of saturable excitonic emitters.
Main Results:
- Developed a microscopic quantum framework for modeling SLRs.
- Demonstrated coupling to collective vibrational modes in molecular optomechanics.
- Showcased nonlinear switching of SLR conditions using emitter nonlinearities.
- Identified nonlinear phase-matching phenomena in pump-probe experiments.
Conclusions:
- The derived quantum theory provides a comprehensive microscopic description of SLRs.
- Enables modeling of complex interactions with quantum emitters and nonlinear materials.
- Opens avenues for exploring quantum phenomena and novel applications in nanophotonics.

34.2K
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...

01:28Standing Waves in a Cavity
1.6K
A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

01:14Sound Waves: Resonance
3.6K
Resonance is produced depending on the boundary conditions imposed on a wave. Resonance can be produced in a string under tension with symmetrical boundary conditions (i.e., has a node at each end). A node is defined as a fixed point where the string does not move. The symmetrical boundary conditions result in some frequencies resonating and producing standing waves, while other frequencies interfere destructively. Sound waves can resonate in a hollow tube, and the frequencies of the sound...

01:26Resonance in an AC Circuit
2.6K
The property of an inductor makes it resist any change in the current passing through it, while the property of a capacitor is to build up the charge across its terminals. Hence, if an inductor and capacitor are connected in series, they have opposite effects on the relative phase between current and voltage. The current through the circuit undergoes forced oscillation at the frequency of the source. The resistance term in an R-L-C circuit acts as a damping term because power is dissipated...

01:23Parallel Resonance

The parallel RLC circuit is an arrangement where the resistor (R), inductor (L), and capacitor (C) are all connected to the same nodes and, as a result, share the same voltage across them. The parallel RLC circuit is analyzed in terms of admittance (Y), which reflects the ease with which current can flow. The admittance is given by:

01:17Series Resonance

The RLC circuit impedance is defined as the ratio of the supply voltage to the circuit current. Resonance in such a circuit occurs when the imaginary part of this impedance equals zero. This specific condition means that the inductive reactance is exactly equal to the capacitive reactance. The frequency at which this happens is known as the resonant frequency. Mathematically, the resonant frequency is inversely proportional to the square root of the product of the inductance (L) and capacitance...
