Morphology-resolved scrambling in a chaotic quantum billiard
Pranaya Pratik Das
Chaotic quantum systems can retain spatial memory through scarred eigenstates, but whether these static structures control scrambling remains unclear. This work establishes a morph…
Dimensional Crossover of Mass Anisotropy in Ta-doped WTe2
P. Das, D. Das, P. Kumar +2
The observation of extremely large magnetoresistance in WTe2 has attracted considerable attention towards understanding its underlying origin. With its layered van der Waals struct…
Chaos in cymatics-inspired Gaussian landscapes
Tanmayee Patra, Pranaya Pratik Das, Biplab Ganguli
This paper presents a focused investigation of a conservative chaotic system, specifically within the context of a two-dimensional harmonic potential well. We analyse the emergence…
Classical and quantum chaos in bean- and peanut-shaped billiards
Pranaya Pratik Das, Tanmayee Patra, Biplab Ganguli
The geometry of a billiard boundary fundamentally governs its dynamics, ranging from integrable to mixed and fully chaotic regimes. Bean- and peanut-shaped billiards have varying c…
Out-of-Time-Order-Correlation in perturbed quantum wells
Pranaya Pratik Das, Biplab Ganguli
Out-of-Time-Order-Correlator (OTOC) and Loschmidt Echo (LE) are commonly regarded as diagnostic tools for chaos, although they may yield misleading results because of various other…
Cyclically Symmetric Thomas Oscillators As Swarmalators : A paradigm for Active Fluids & Pattern Formation
Vinesh Vijayan, Pranaya Pratik Das
In this letter, we demonstrate the cyclically symmetric Thomas oscillators as swarmalators and describe their possible collective dynamics. We achieve this by sewing Kuromoto-type…
Dynamics of a Charged Thomas Oscillator in an External Magnetic Field
Vinesh Vijayan, Pranaya Pratik Das
In this letter, we provide a detailed numerical examination of the dynamics of a charged Thomas oscillator in an external magnetic field. We do so by adopting and then modifying th…
