Spatial, Spectral and Temporal Response of High Intensity Laser Plasma Mirrors- Direct Observation of the Ponderomotive Push
Sk Rakeeb, Animesh Sharma, Sagar Dam +5
Plasma-based optics have emerged as a powerful platform for manipulating and amplifying ultra-intense laser pulses. However, the inherently nonlinear and dynamic nature of plasma l…
Chaos aided regime of Laser/Electromagnetic Energy Absorption by plasma
Rohit Juneja, Amita Das, Trishul Dhalia +1
The absorption of laser energy by plasma is of paramount importance for various applications. Collisional and resonant processes are often invoked for this purpose. However, in som…
Efficient electron heating by laser in finite sized plasma micro-globular targets by repeated collisions of surface and bulk waves
Animesh Sharma, Amita Das, G Ravindra Kumar
A new mechanism of enhanced laser energy absorption in plasma microglobules is demonstrated with the help of two-dimensional Particle-In-Cell (PIC) simulations. The mechanism relie…
Bulk and surface dominated phenomena and the formation of pentagonal structures in 2-D strongly coupled finite dust clusters
Mamta Yadav, Aman Singh Katariya, Animesh Sharma +1
This paper explores the prevalence of size-dependent aspects in the context of dust clusters with the help of Molecular Dynamics (MD) simulations in two dimensions. The transition…
Diffusive transport of a 2-D magnetized dusty plasma cloud
Aman Singh Katariya, Amita Das, Animesh Sharma +1
Dusty plasma medium turns out to be an ideal system for studying the strongly coupled behavior of matter. The large size and slow response make their dynamics suitable to be captur…
Evolution of Shielding Cloud Under Oscillatory External Forcing in Strongly Coupled Ultracold Neutral Plasma
Mamta Yadav, Aman Singh Katariya, Animesh Sharma +1
This paper investigates the dynamics of crystalline clusters observed in Molecular Dynamics (MD) studies conducted earlier [Yadav, M., et al. Physical Review E, 107(5), 055214(2023…
