Optical properties of potential-inserted quantum wells in the near infrared and Terahertz ranges

, 2016
We propose an engineering of the optical properties of GaAs/AlGaAs quantum wells using AlAs and InAs monolayer insertions. A quantitative study of the effects of the monolayer position and the well thickness on the interband and intersubband transitions,

To maximize or not to maximize the free energy of glassy systems, !=? [PDF]

, 1995
The static free energy of glassy systems can be expressed in terms of the Parisi order parameter function. When this function has a discontinuity, the location of the step is determined by maximizing the free energy.

Use of a 3D Workpiece to Inductively Heat an Ammonia Cracking Reactor

Sustainable Chemistry
Ammonia, widely regarded as the “hydrogen carrier of the future,” offers high hydrogen content, ease of production, and a well-established infrastructure for handling and transportation globally. Meanwhile, ammonia cracking requires a heat supply at high

Hagedorn transition for strings on pp-waves and tori with chemical potentials

, 2002
It has been conjectured that string theory in a pp-wave background is dual to a sector of N=4 supersymmetric Yang-Mills theory. We study the Hagedorn transition for free strings in this background.

The Transition from Singly to Multiply-Charged Anomalous Cosmic Rays: Simulation and Interpretation of SAMPEX Observations [PDF]

, 2000
Multiply-charged anomalous cosmic rays (ACRs) can arise when singly-charged ACR ions are stripped of one or more of their electrons during their acceleration via, e.g., the process of diffusive shock-drift acceleration at the solar-wind termination shock.

Strangeness and pion production as signals of QCD phase transition [PDF]

, 2005
A systematic analysis of data on strangeness and pion production in nucleon–nucleon and central nucleus–nucleus collisions is presented. It is shown that at all collision energies the pion/baryon and strangeness/pion ratios indicate saturation with the ...

Johari-Goldstein relaxation far below Tg: Experimental evidence for the Gardner transition in structural glasses?

, 2017
Experimental evidence for the Gardner transition, theoretically predicted to arise deep in the glassy state of matter, is scarce. At this transition, the energy landscape sensed by the particles forming the glass is expected to become more complex.

The Impact of System Sizing and Water Temperature on the Thermal Characteristics of Floating Photovoltaic Systems

Energies
Accurately calculating the annual yield of floating PV (FPV) systems necessitates incorporating appropriate FPV-specific heat loss coefficients into the calculation, including both wind-dependent and wind-independent factors.
