Stability of Collective Neutrino Oscillations -- A Distributional Approach
Rupak Majumder, Dwaipayan Mukherjee, Shamik Gupta +1
We study the stability of collective neutrino oscillations using a distributional approach motivated by the statistical mechanics of Kuramoto synchronization. Treating the ensemble…
Constructing Non-Hermitian Theories with Tunable Exceptional Points and Controlled State Purification
Soumya Kanti Pal, Rupak Majumder, Shamik Gupta
Exceptional points (EP's) are a hallmark of non-Hermitian quantum systems. We show that momentum-space deformation provides a general design principle for creating and controlling…
Analytical approach to subsystem resetting in generalized Kuramoto models
Rupak Majumder, Anish Acharya, Shamik Gupta
Stochastic resetting has emerged as a powerful mechanism for driving systems into nonequilibrium stationary states with tunable properties. While most existing studies focus on glo…
Synchronization with Annealed Disorder and Higher-Harmonic Interactions in Arbitrary Dimensions: When Two Dimensions Are Special
Rupak Majumder, Shamik Gupta
The impact of disorder on collective phenomena depends crucially on whether it is quenched or annealed. In synchronization problems, quenched disorder in higher dimensional Kuramot…
Finite-size fluctuations for stochastic coupled oscillators: A general theory
Rupak Majumder, Julien Barré, Shamik Gupta
Phase transitions, sharp in the thermodynamic limit, get smeared in finite systems where macroscopic order-parameter fluctuations dominate. Achieving a coherent and complete theore…
Manipulating phases in many-body interacting systems with subsystem resetting
Anish Acharya, Rupak Majumder, Shamik Gupta
Stabilizing thermodynamically unstable phases in many-body systems, such as suppressing pathological neuronal synchronization in Parkinson's disease or maintaining magnetic order a…
Kuramoto model subject to subsystem resetting: How resetting a part of the system may synchronize the whole of it
Rupak Majumder, Rohitashwa Chattopadhyay, Shamik Gupta
We introduce and investigate the effects of a new class of stochastic resetting protocol called subsystem resetting, whereby a subset of the system constituents in a many-body inte…
