Summary
Quantum emitters interacting with graphene plasmons (GPs) can excite GPs and undergo excitation, especially at high speeds. This research simulates quantum effects like the dynamical Casimir and Unruh effects.
Area of Science:
- Quantum optics

Background:
- Graphene plasmons (GPs) offer unique electromagnetic properties.
- Interactions between quantum emitters and plasmonic fields are of significant interest.
Purpose of the Study:
- Investigate the transmission of a quantum emitter through a graphene nanosheet.
- Explore the excitation of graphene plasmons by a quantum emitter.
- Analyze the potential for simulating quantum field phenomena.
Main Methods:
- Theoretical investigation of a two-level quantum emitter interacting with localized GPs.
- Inclusion of counterrotating terms in the interaction Hamiltonian.
- Analysis of emitter dynamics and GP emission probability.
Main Results:
- Significant nonadiabatic processes observed due to GP field distribution.
- High probability of quantum emitter excitation and simultaneous GP emission at speeds ~10^-4 c.

3.9K
Molecules possess discrete energy levels called quantum states. Unlike atoms, which have simpler energy levels, molecules possess additional rotational and vibrational energy levels. Each energy level is separated by an energy gap, with the gaps between adjacent electronic, vibrational, and rotational levels varying significantly. The three types of energy levels in a diatomic molecule are shown in Figure 1.

2.7K
Photoluminescence is a process where a molecule absorbs light energy and re-emits it in the form of light. This phenomenon occurs when a substance absorbs photons, promoting its electrons to higher energy level excited states, followed by a relaxation process in which the electrons return to their original ground state energy levels and emit light. Photoluminescence is widely observed in various materials, including semiconductors, and organic and inorganic compounds.

72.9K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

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...

Ideally, an unpaired electron shows a single peak in the EPR spectrum due to the transition between the two spin energy states. However, coupling interactions can occur between the spins of the unpaired electron and any neighboring spin-active nuclei. This hyperfine coupling results in hyperfine splitting, where the EPR signal is split into multiplets. The signals split into 2nI + 1 peaks, where n is the number of equivalent nuclei and I is the nuclear spin. These splitting patterns provide...

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 the...
