The study of nonlinear electron-acoustic (EA) wave propagation is one of the predominant research areas in space plasma environments. The concept of EA waves was developed by Fried and Gould (-- removed HTML --) (-- removed HTML --) 1 (-- removed HTML --) (-- removed HTML --) for the first time in an unmagnetized plasma, and they observed that electron plasma oscillations can appear in a continuous formulation without correlation in the presence of collective effects, making the physics non-trivial

Research Statement Zhen Liu What is the (next accessible) scale of new physics? We do not have a clear answer. We are living through a challenging and exciting era, in sharp contrast to the situation of the past (half) century in physics. The discovery of the Higgs boson, the determination of the non-zero θ13 neutrino mixing parameter, the first detection of gravitation waves, and many greatly improved experimental probes for new physics beyond the standard model mark the great triumphs of our understandings

Ultra-short laser pulses allow us to bring metals into a strongly nonequilibrium state with hot electrons and a cold lattice. (-- removed HTML --) (-- removed HTML --) 1 (-- removed HTML --) (-- removed HTML --) The term “hot electrons” in the present work implies a subsystem of electrons having a higher temperature than the temperature of the ionic subsystem. The study of properties of such states is important for a wide range of applications in geophysics, high-pressure physics, condensed matter

The development of LED started with the first Light Emitting Diode appears at early of twentieth century. The first LED light was produced by touching the SiC crystal with metal electrodes so that a rectifying Schottky contact was formed. In 1964, Eastman discovered that light is formed in Schottky Diodes in reverse-biased conditions. Infrared LEDs and Lasers based in GaAs were first reported in 1962 followed by the AlGaAs/GaAs devices in the early of 1960s. The first demonstration on resonant-cavity

What is the (next accessible) scale of new physics? We do not have a clear answer. We are living through a challenging and exciting era, in sharp contrast to the situation in the past (half) century in physics. The discovery of the Higgs boson, the determination of the non-zero $\theta_ {13} $ neutrino mixing parameter, the first detection of gravitation waves, and many significantly improved experimental probes for new physics beyond the standard model mark the great triumphs of our understandings

CONCEPT OF INTUITION AND CONSCIOUSNESS: A STUDY OF HERO IN SRI AUROBINDO‘S PLAY VASAVADATTA Sri Aurobindo (1872-1950) was a major Indian English playwright. He wrote five complete and six incomplete verse plays during 1891-1916.He was a great philosopher also. Glimpses of his philosophy such as idea of evolution and consciousness, intuition and love can be seen as major themes of his plays. All his plays are in the form of in poetry and romance. This present research article will study the hero

It has been the main topic of this thesis to establish the link between state-of-the-art theoretical tools and typical spectroscopies in order to contribute to the understanding of complex many-body compounds. The synergy between theory and experiment was given a special attention. The main spectroscopy studied theoretically by the works in this thesis is photoemission and its variants. In particular, we worked out the effects of correlations in many-body systems as manifested in spectroscopic quantities

Ch 1 Each different scientist made an impact in some way to the origins of an atom. Lucretius’s work, De Rerum Natura, was the basis for many future scientists. Robert Boyle was a very religious man and people believed that was the reason for him not marrying. Boyle constructed the idea that the air was made up of different particles with each having different functions. Huygens first thought of the idea that waves of light moved in a spherical shape. His wave theory is still used today along with

In the study of radially expanding solar wind, it is well established that various kinetic plasma instabilities limit the unchecked increase of temperature anisotropies. Observations made in the solar wind show that protons, electrons, and alpha particles exhibit varying degrees of temperature anisotropies.

Thought that bismuth is the newest discovered metal in human history? Wrong. Bismuth is already known for a longer period of time. It is a bright metal with a white color and that is exactly where the name ‘bismuth’ comes from. About five hundred years ago a Swiss scientist Theophrastus Bombastus von Hohenheim (1493 – 1541) used the metal, a mineral that was drawn (gemutet) in the fields (in den Wiesen) in Saxony. This caused the Swiss scientist to come up with the name ‘wissmut’. And because of
