Moving Detector Quantum Walk with Random Relocation
Md Aquib Molla, Sanchari Goswami
We study a discrete-time quantum walk in presence of a detector at initially. The detector here is repeatedly removed after a span of , the removal time, and reinserted…
Does Partial Consumption Help Foraging?
Md Aquib Molla, Sanchari Goswami
In this work, we consider partial consumption of food by a forager in presence of a threshold energy level. The forager considered here can survive for steps without food, name…
Percolative Instabilities and Sparse-Limit Fractality in 1T-TaS
Poulomi Maji, Md Aquib Molla, Koushik Dey +13
The low-temperature metallic phase of 1T-TaS2 may originate from current- and voltage-driven destabilization of the commensurate charge density wave (CDW) in a strongly correlated…
Forager with intermittent rest: Better for survival?
Md Aquib Molla, Sanchari Goswami, Parongama Sen
We study the fate of a forager who searches for food performing a random walk on lattices. The forager consumes the available food on the site it visits and leaves it depleted but…
An Insight of Heart-Like Systems with Percolation
Md Aquib Molla, Sanchari Goswami
We study the signal percolation through heart-like biological system. Starting from an initial distribution of waiting and inactive cells with probabilities and respect…
Kinetic Models of Wealth Distribution Having Extreme Inequality: Numerical Study of Their Stability Against Random Exchanges
Asim Ghosh, Suchismita Banerjee, Sanchari Goswami +2
In view of some persistent recent reports on a singular kind of growth of the world wealth inequality, where a finite (often handful) number of people tend to possess more than the…
Quantum Walker in Presence of a Moving Detector
Md Aquib Molla, Sanchari Goswami
In this work, we study the effect of a moving detector on a discrete time one dimensional Quantum Random Walk where the movement is realized in the form of hopping/shifts. The occu…
A poor agent and subsidy: an investigation through CCM model
Sanchari Goswami
In this work, the dynamics of agents below a \textit{threshold line} in some modified CCM type kinetic wealth exchange models are studied. These agents are eligible for subsidy as…
Current reversal in interacting colloids under time-periodic drive
Shubhashis Rana, Sanchari Goswami, Sakuntala Chatterjee +1
Using molecular dynamics simulations, we study particle-transport in a system of interacting colloidal particles on a ring, where the system is driven by a time-dependent external…
Fiber bundle model under heterogeneous loading
Subhadeep Roy, Sanchari Goswami
The present work deals with the behavior of fiber bundle model under heterogeneous loading condition. The model is explored both in the mean-field limit as well as with local stres…
A Recipe for Composite Materials: An Approach through Fiber Bundle Model
Subhadeep Roy, Sanchari Goswami
Strengthening of materials and preventing abrupt fracture are really challenging jobs in the field of engineering and material science. Such problems can be resolved by using compo…
Agent based models for wealth distribution with preference in interaction
Sanchari Goswami, Parongama Sen
We propose a set of conservative models in which agents exchange wealth with a preference in the choice of interacting agents in different ways. The common feature in all the model…
Kinetic Exchange Models in Economics and Sociology
Sanchari Goswami, Anirban Chakraborti
In this article, we briefly review the different aspects and applications of kinetic exchange models in economics and sociology. Our main aim is to show in what manner the kinetic…
Quantum random walk : effect of quenching
Sanchari Goswami, Parongama Sen
We study the effect of quenching on a discrete quantum random walk by removing a detector placed at a position abruptly at time from its path. The results show that thi…
Behavior of heat capacity of an attractive Bose-Einstein Condensate approaching collapse
Sanchari Goswami, Tapan Kumar Das, Anindya Biswas
We report calculation of heat capacity of an attractive Bose-Einstein condensate, with the number N of bosons increasing and eventually approaching the critical number Ncr for coll…
Antipersistent dynamics in kinetic models of wealth exchange
Sanchari Goswami, Arnab Chatterjee, Parongama Sen
We investigate the detailed dynamics of gains and losses made by agents in some kinetic models of wealth exchange. The concept of a walk in an abstract gain-loss space for the agen…
Complex Networks: effect of subtle changes in nature of randomness
Sanchari Goswami, Soham Biswas, Parongama Sen
In two different classes of network models, namely, the Watts Strogatz type and the Euclidean type, subtle changes have been introduced in the randomness. In the Watts Strogatz typ…
Thermodynamic properties of ultracold Bose gas: transition exponents and universality
Sanchari Goswami, Tapan Kumar Das, Anindya Biswas
We report exact numerical calculation of chemical potential, condensate fraction and specific heat of non-interacting bosons confined in an isotropic harmonic oscillator trap i…
Quantum Persistence: A Random Walk Scenario
Sanchari Goswami, Parongama Sen, Arnab Das
In this paper we extend the concept of persistence, well defined for classical stochastic dynamics, to the context of quantum dynamics. We demonstrate the idea via quantum random w…
Persistence of unvisited sites in presence of a quantum random walker
Sanchari Goswami, Parongama Sen
A study of persistence dynamics is made for the first time in a quantum system by considering the dynamics of a quantum random walk. For a discrete walk on a line starting at …
