Acoustic Gain in Solids due to Piezoelectricity, Flexoelectricity, and Electrostriction [PDF]
Advanced Functional Materials, 2020 AbstractA quantitative discussion of the combined influence of three electromechanical effects: piezoelectricity, flexoelectricity, and electrostriction in solids is provided for acoustic absorption and gain. While piezoelectricity occurs in non‐centrosymmetric materials only, flexoelectricity and electrostriction exist in all materials.

Biomolecular solid-state NMR spectroscopy at 1200 MHz: the gain in resolution [PDF]
Journal of Biomolecular NMR, 2021 AbstractProgress in NMR in general and in biomolecular applications in particular is driven by increasing magnetic-field strengths leading to improved resolution and sensitivity of the NMR spectra. Recently, persistent superconducting magnets at a magnetic field strength (magnetic induction) of 28.2 T corresponding to 1200 MHz proton resonance ...

Optical Gain in Solids after Ultrafast Strong-Field Excitation [PDF]
Physical Review Letters, 2021 Multiphoton excitation of a solid by a few-cycle, intense laser pulse forms a very nonequilibrium distribution of charge carriers, where occupation probabilities do not necessarily decrease with energy. Within a fraction of the pulse, significant population inversion can emerge between pairs of valence-band states with a dipole-allowed transition ...

Quantitative Electrochemical Control over Optical Gain in Quantum-Dot Solids [PDF]
ACS Nano, 2020 Realizing solution processed quantum dot (QD) lasers is one of the holy-grails of nanoscience. The reason that QD lasers are not yet commercialized is that the lasing threshold is too high: one needs > 1 exciton per QD, which is hard to achieve due to fast non-radiative Auger recombination.
