How to distinguish squeezed and coherent phonons in femtosecond x-ray diffuse scattering
T. Henighan, M. Trigo, M. Chollet +9
Impulsive optical excitation can generate both coherent and squeezed phonons. The expectation value of the phonon displacement oscillates at the mode frequency for the cohe…
Discrete Fresnel Transform and Its Circular Convolution
Xing Ouyang, Cleitus Antony, Fatima Gunning +2
Discrete trigonometric transformations, such as the discrete Fourier and cosine/sine transforms, are important in a variety of applications due to their useful properties. For exam…
Structural, electronic, and optical properties of -plane InGaN/GaN quantum wells: Insights from experiment and atomistic theory
S. Schulz, D. P. Tanner, E. P. O'Reilly +13
In this paper we present a detailed analysis of the structural, electronic, and optical properties of an -plane (In,Ga)N/GaN quantum well structure grown by metal organic vapor…
Al4SiC4 würtzite crystal: structural, optoelectronic, elastic and piezoelectric properties
L. Pedesseau, J. Even, M. Modreanu +3
New experimental results supported by theoretical analyses are proposed for aluminum silicon carbide (Al4SiC4). A state of the art implementation of the Density Functional Theory i…
Single pairs of time-bin entangled photons
Marijn A. M. Versteegh, Michael E. Reimer, Aafke A. van den Berg +5
Time-bin entangled photons are ideal for long-distance quantum communication via optical fibers. Here we present a source where, even at high creation rates, each excitation pulse…
Using network science and text analytics to produce surveys in a scientific topic
Filipi N. Silva, Diego R. Amancio, Maria Bardosova +2
The use of science to understand its own structure is becoming popular, but understanding the organization of knowledge areas is still limited because some patterns are only discov…
