DOI: 10.1002/qj.3228
Abstract: This work investigates the statistical linkage between upper-tropospheric transient Rossby wave packets (RWPs) and lower-tropospheric temperature extremes in the Northern Hemisphere during the period 1979–2015. Data from ERA-Interim reanalyses are used for the diagnosis of… read more here.

DOI: 10.1021/acsphotonics.8b01437
Abstract: Tilted-pulse-front pulses, which are produced via dispersive devices that introduce angular dispersion, are useful in many areas of nonlinear optics. Such pulses typically have large transverse cro... read more here.

DOI: 10.1029/2020gl091452
Abstract: Persistent dry and wet spells can arise from stationary weather situations or recurrent flow patterns and result in significant socio‐economic impacts. Here, we study the effects of recurrent synoptic‐scale transient Rossby wave packets (RRWPs) on… read more here.

DOI: 10.1063/1.5008852
Abstract: We use femtosecond laser pulses to generate coherent longitudinal acoustic phonons at frequencies of 1–1.4 THz and study their propagation in GaN-based structures at room temperature. Two InGaN-GaN multiple-quantum-well (MQW) structures separated by a 2.3 μm-thick GaN… read more here.

DOI: 10.1063/1.5096954
Abstract: We complete our study on the uncertainties in position and momentum associated with the semiclassical Hagedorn wave packets by first filling in a technical gap in the dynamics of bound states for isochronous potentials. We… read more here.
