1 PHz of Coherent Bandwidth from a Compact Fiber Device

Laser &Photonics Reviews, EarlyView.
A coherent comb spectrum with an unprecedented bandwidth of 1 PHz, spanning from the deep ultraviolet (280 nm) to the mid‐infrared (2700 nm), is generated by a compact fiber device. The integrated, novel pulse purification technology enables broadband dispersion control and the synthesis of low‐noise, single‐cycle near‐infrared pulses with a clean ...

The One‐Dimensional Coulomb Hamiltonian: Properties of Its Birman–Schwinger Operator

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The objective of the present paper is to study in detail the properties of the Birman–Schwinger operator for a self‐adjoint realization of the one‐dimensional Hamiltonian with the Coulomb potential, both when the Hamiltonian is defined only on ℝ+$$ {\mathbb{R}}_{+} $$ and when it is defined on the whole real line.

Comparative Insights Into the Structural, Electronic, Elastic, Vibrational, and Optical Properties of Rare‐Earth Palladium Borides RBPd3 (R = Lu, Yb)

Nano Select, EarlyView.
This study focuses on the ground‐state properties of two rare earth palladium borides, LuBPd3 and YbBPd3. The WIEN2k package is used to investigate the properties. The compounds’ exceptional thermal and optoelectronic properties make them suitable for high‐temperature applications, UV absorbers, and infrared (IR) shielding materials.
