|January 7, 2017
Summary
Detuned electromagnetic pulses can cause Rabi oscillations in atoms with initial coherence, leading to backward light generation. This finding is useful for quantum applications like the QASER scheme.
Area of Science:
- Quantum optics
- Atomic physics
- Nonlinear optics
Background:
- Adiabatic electromagnetic pulses typically prevent Rabi oscillations in atoms.
- Nonzero initial coherence in atoms is a prerequisite for observing Rabi oscillations under adiabatic conditions.
Purpose of the Study:
- To investigate the effect of initial atomic coherence on atomic population dynamics under adiabatic electromagnetic pulse excitation.
- To derive analytical solutions for atomic population evolution in the presence of Rabi oscillations.
- To explore potential applications in backward light generation and quantum systems.
Main Methods:
- Theoretical analysis of atomic population dynamics.
- Derivation of analytical solutions for the atomic population.
- Modeling of light-atom interaction under adiabatic pulse conditions.
Main Results:
- Adiabatic electromagnetic pulses can induce Rabi oscillations in atomic populations if initial coherence is present.
- Analytical solutions for the time-dependent atomic population (ρaa(t)) were obtained.
- The findings suggest a method for generating coherent light in the backward direction.
Conclusions:
- Initial atomic coherence is crucial for observing Rabi oscillations with detuned adiabatic pulses.
- The study provides a pathway for backward coherent light generation using Rabi oscillations.
- Applications in quantum-assisted-stimulated-emission-Rabi (QASER) schemes are proposed.

3.3K
The earth's gravitational field produces a 'twisting force' perpendicular to the angular momentum of a spinning mass (such as a spinning top) that causes the mass to 'wobble' around the gravitational field axis in a phenomenon called precession. Similarly, the magnetic moment (μ) of a spinning nucleus precesses due to an external magnetic field directed along the z-axis. The precession of the magnetic moment vector about the magnetic field is called Larmor precession,...

01:04Oscillations about an Equilibrium Position
7.1K
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

01:30Oscillations In An LC Circuit
3.3K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

01:18Adiabatic Processes for an Ideal Gas
4.3K
When an ideal gas is compressed adiabatically, that is, without adding heat, work is done on it, and its temperature increases. In an adiabatic expansion, the gas does work, and its temperature drops. Adiabatic compressions actually occur in the cylinders of a car, where the compressions of the gas-air mixture take place so quickly that there is no time for the mixture to exchange heat with its environment. Nevertheless, because work is done on the mixture during the compression, its...

In atomic emission spectroscopy (AES), high-temperature atomizers excite a broad range of elements and molecules that generate complex emissions from sources such as oxides, hydroxides, and flame combustion products in the flame or plasma. Several strategies can be employed to minimize spectral interferences caused by overlapping emission lines or bands. These include increasing instrument resolution, choosing alternative emission lines, optimally placing the detector in low-background regions,...
