Extending the Feynman variational principle and analytical methods to lattice polarons
S. N. Klimin, J. Tempere, M. Houtput +6
We develop and compare several analytical approximations for the ground state and zero-temperature polaron dispersion in finite-width, nonparabolic conduction bands. The main focus…
Negative magnetoresistance in strained -Sn and -SnGe films in an in-plane magnetic field
Sunny Phan, Andrei Kogan, Jesse Thompson +3
To test the hypothesis that the chiral anomaly is responsible for negative magnetoresitance (MR) in \atn{}, we have studied magnetotransport in strained, epitaxial films of pure \a…
Euclid: Discovery of bright Lyman-break galaxies in UltraVISTA and Euclid COSMOS
R. G. Varadaraj, R. A. A. Bowler, M. J. Jarvis +163
We present a search for Lyman-break galaxies using the near-infrared UltraVISTA survey in the COSMOS field, reaching depths in of 26.2.…
Energy density driven ultrafast electronic excitations in a cuprate superconductor
Alessandra Milloch, Francesco Proietto, Naman Agarwal +7
Controlling nonequilibrium dynamics in quantum materials requires ultrafast probes with spectral selectivity. We report femtosecond reflectivity measurements on the cuprate superco…
Thackeray's globules in IC 2944: the rocket effect revisited by ALMA
M. Fernández-López, L. A. Zapata, B. Reipurth +4
The prominent Thackeray's globules are a collection of cloudlets seen in silhouette against the bright emission of the IC 2944 HII region, ionized by the Collinder 249 cluster of e…
Favorable modifications of Scrape-Off Layer (SOL) heat flux width through pulsed fuelling in ADITYA-U Tokamak
SK Injamul Hoque, Harshita Raj, Ritu Dey +19
Enhancement of the scrape-off layer (SOL) heat flux width has been observed in the ADITYA-U Tokamak following the injection of short fuel gas pulses. A notable reduction in paralle…
