Physics - History and Philosophy of PhysicsThe double slit interference experiment has been famously described by Richard Feynman as containing the "only mystery of quantum mechanics". The history of quantum mechanics is intimately linked with the discovery of the dual nature of matter and radiation....
driven analysis framework for matter at the atomic scale involves transforming the Cartesian coordinates that describe the positions of the atoms in the form of a representation that obeys the same symmetries as the properties of interest, and in general reflects the physical nature of the problem....
Recent advances in tunable laser sources have stimulated a great deal of interest in the study of intense field-matter interaction physics. Whenever a molecule interacts with an intense radiation field, it can absorb multiple photons from the field and make a transition either to an excited state...
The wave nature of matter is a key ingredient of quantum physics and yet it defies our classical intuition. First proposed by Louis de Broglie a century ago, it has since been confirmed with a variety of particles from electrons up to molecules. Here we demonstrate new high-contrast quantum ...
Characteristics of Atoms and Molecules Atomic Structure Atoms are the smallest units of matter that retain the characteristics of an element. They consist of a positively charged nucleus, containing protons and neutrons, surrounded by a cloud of negatively charged electrons. The nucleus, located at th...
remarkable abilities in characterizing complex sets of data with a high degree of accuracy, and has been widely utilized in genetics45, condensed-matter physics46, and material science47. We show here that it can effectively deal with the complicated decoding in HHS (see Methods and Supplementary...
The chapter discusses the symbols used for atoms, how formulas are determined, and solutions and their concentrations. It explains three laws describing the behavior of matter that were known before the acceptance of atomic theory. The chapter further explains how atomic theory applies to those laws...
