text: The elimination of rain evaporation in the planetary boundary layer (PBL)
has been found to lead to convective self‐aggregation (CSA) even without radiative
feedback, but the precise mechanisms underlying this phenomenon remain unclear.
We conducted cloud‐resolving simulations with two domain sizes and progressively
reduced rain evaporation in the PBL. Surprisingly, CSA only occurred when rain
evaporation was almost completely removed. The additional convective heating resulting
from the reduction of evaporative cooling in the moist patch was found to be the
trigger, thereafter a dry subsidence intrusion into the PBL in the dry patch takes
over and sets CSA in motion. Temperature and moisture anomalies oppose each other
in their buoyancy effects, hence explaining the need for almost total rain evaporation
removal. We also found radiative cooling and not cold pools to be the leading
cause for the comparative ease of CSA to take place in the larger domain.

text: We demonstrate the failure of the adiabatic Born-Oppenheimer approximation
to describe the ground state of a quantum impurity within an ultracold Fermi gas
despite substantial mass differences between the bath and impurity species. Increasing
repulsion leads to the appearance of nonadiabatic couplings between the fast bath
and slow impurity degrees of freedom, which reduce the parity symmetry of the
latter according to the pseudo Jahn-Teller effect. The presence of this mechanism
is associated to a conical intersection involving the impurity position and the
inverse of the interaction strength, which acts as a synthetic dimension. We elucidate
the presence of these effects via a detailed ground-state analysis involving the
comparison of ab initio fully correlated simulations with effective models. Our
study suggests ultracold atomic ensembles as potent emulators of complex molecular
phenomena.

text: Thermoelectric materials convert heat into electricity, with a broad range
of applications near room temperature (RT). However, the library of RT high-performance
materials is limited. Traditional high-temperature synthetic methods constrain
the range of materials achievable, hindering the ability to surpass crystal structure
limitations and engineer defects. Here, a solution-based synthetic approach is
introduced, enabling RT synthesis of powders and exploration of densification
at lower temperatures to influence the material's microstructure. The approach
is exemplified by Ag2Se, an n-type alternative to bismuth telluride. It is demonstrated
that the concentration of Ag interstitials, grain boundaries, and dislocations
are directly correlated to the sintering temperature, and achieve a figure of
merit of 1.1 from RT to 100 °C after optimization. Moreover, insights into and
resolve Ag2Se's challenges are provided, including stoichiometry issues leading
to irreproducible performances. This work highlights the potential of RT solution
synthesis in expanding the repertoire of high-performance thermoelectric materials
for practical applications.

text: Current knowledge suggests a drought Indian monsoon (perhaps a severe one)
when the El Nino Southern Oscillation and Pacific Decadal Oscillation each exhibit
positive phases (a joint positive phase). For the monsoons, which are exceptions
in this regard, we found northeast India often gets excess pre-monsoon rainfall.
Further investigation reveals that this excess pre-monsoon rainfall is produced
by the interaction of the large-scale circulation associated with the joint phase
with the mountains in northeast India. We posit that a warmer troposphere, a consequence
of excess rainfall over northeast India, drives a stronger monsoon circulation
and enhances monsoon rainfall over central India. Hence, we argue that pre-monsoon
rainfall over northeast India can be used for seasonal monsoon rainfall prediction
over central India. Most importantly, its predictive value is at its peak when
the Pacific Ocean exhibits a joint positive phase and the threat of extreme drought
monsoon looms over India.
