Skin-Anderson Localization Transition in Strongly Coupled Disordered Non-Hermitian Chains
S Rahul
The interplay between disorder and non-Hermitian effects gives rise to a variety of intriguing localization phenomena. While disorder tends to localize the eigenstates through Ande…
Controlling energy spectra and skin effect via boundary conditions in non-Hermitian lattices
S Rahul, Pasquale Marra
Non-Hermitian systems exhibit unique spectral properties, including the non-Hermitian skin effect and exceptional points, often influenced by boundary conditions. The modulation of…
Competing Localizations on Disordered Non-Hermitian Random Graph Lattice
S Rahul, A Harshitha
Phase transitions in one-dimensional lattice systems are well established and have been extensively studied within both Hermitian and non-Hermitian frameworks. In this work, we ext…
Zero Indirect Band Gap in Non-Hermitian Systems
S Rahul, Giandomenico Palumbo
Zero indirect gaps in band models are typically viewed as unstable and achievable only through fine-tuning. Recent works, however, have revealed robust semimetallic phases in Hermi…
A compact laser-plasma source for high-repetition-rate bi-modal X-ray and electron imaging
Angana Mondal, Ratul Sabui, Sonali Khanna +5
Bright sources of high-energy X-rays and electrons are indispensable tools in advanced imaging. Yet, current laser-driven systems typically support only single-modality imaging, re…
Enhanced hot electron generation from liquid jets in moderate intensity laser-plasma interactions
Ratul Sabui, S. V. Rahul, Angana Mondal +4
We report the generation of MeV temperature electrons using sub-terawatt laser systems with a liquid methanol jet as a target. Remarkably, even at laser intensities of 1016W/cm2, l…
Laser structured micro-targets generate MeV electron temperature at W/cm
Angana Mondal, Ratul Sabui, Sheroy Tata +14
Relativistic temperature electrons higher than 0.5 MeV are generated typically with laser intensities of about 10 W/cm. Their generation with high repetition rate lase…
Temporal Feedback Control of High-Intensity Laser Pulses to Optimize Ultrafast Heating of Atomic Clusters
M. J. V. Streeter, S. J. D. Dann, J. D. E. Scott +27
We describe how active feedback routines can be applied at limited repetition rate (5 Hz) to optimize high-power TW) laser interactions with clustered gases. Optimization of…
