Summary
Coherent control using ultrafast laser pulses enables manipulation of quantum states in condensed matter. This technique allows precise control over electron and atomic motion in systems like solid para-hydrogen and bismuth crystals.
Area of Science:
- Quantum physics
- Condensed matter physics
- Ultrafast spectroscopy
Background:
- Coherent control is established for gas-phase systems but challenging in condensed matter due to shorter coherence lifetimes.
- Recent advancements enable applying coherent control techniques to condensed matter samples.
Purpose of the Study:
- To demonstrate the application of coherent control to condensed matter systems.
- To explore the manipulation of wave functions and quantum dynamics in various materials.
Main Methods:
- Utilized femtosecond laser pulses for coherent control experiments.
- Employed attosecond time-scale delay scanning for high-resolution control.
- Applied double-pulse interferometry and intensity-modulated laser pulses.
Main Results:
- Achieved coherent control of vibrons in solid para-hydrogen, demonstrating information encoding potential.
- Controlled two-dimensional atomic motion in bismuth crystals by manipulating coherent phonon modes.
- Observed and controlled many-body electron dynamics in ultracold Rydberg atoms.
Conclusions:
- Solid para-hydrogen is a viable medium for coherent control and information storage.
- Attosecond control of multidimensional atomic motion is achievable in condensed matter.
- Coherent control of ultracold Rydberg atoms provides a platform for studying quantum many-body dynamics.

Chemistry is the study of matter and the changes it undergoes. Matter is anything that has mass and occupies space. Matter is all around us; the air, water, soil, mountains, even our bodies are all examples of matter. Matter is divided into three states — solid, liquid, and gas — that are commonly found on earth. The fourth state of matter, plasma, occurs naturally in the interiors of stars.

01:33Aldol Condensation vs Claisen Condensation
7.9K
Aldol condensation is an acid or base-catalyzed condensation between aldehydes or ketones to give an α,ꞵ-unsaturated carbonyl compound. A base-promoted condensation between ester molecules to produce a ꞵ-ketoester is known as the Claisen condensation. In the presence of a base, both reactions involve deprotonation of the acidic α hydrogen to produce the corresponding enolates. The nucleophilic enolates attack their respective nonenolized carbonyl compound forming a tetrahedral...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...

02:39Phase Transitions: Vaporization and Condensation
21.5K
The physical form of a substance changes on changing its temperature. For example, raising the temperature of a liquid causes the liquid to vaporize (convert into vapor). The process is called vaporization—a surface phenomenon. Vaporization occurs when the thermal motion of the molecules overcome the intermolecular forces, and the molecules (at the surface) escape into the gaseous state. When a liquid vaporizes in a closed container, gas molecules cannot escape. As these gas phase molecules...

The earliest recorded discussion of the basic structure of matter comes from ancient Greek philosophers. Leucippus and Democritus argued that all matter was composed of small, finite particles that they called atomos, meaning “indivisible.” Later, Aristotle and others came to the conclusion that matter consisted of various combinations of the four “elements” — fire, earth, air, and water — and could be infinitely divided. Interestingly, these philosophers...
