Selection Rules for Species Coexistence in a Hierarchical May-Leonard Model
Rakesh Samanta, Shraosi Dawn, Sk Jahiruddin +3
One of the central challenges in evolutionary dynamics is understanding why some species combinations persist while others disappear. Although cyclic-interaction models have provid…
On the Relation Between String Order Parameters, Entanglement, and Dynamical Quantum Phase Transitions in Topological Dynamics
Sirshendu Bhattacharyya, Szczepan Głodzik, Nicholas Sedlmayr
Topological order is defined by topological invariants, rather than symmetries and local order parameters. Nonetheless some topological phases can be characterized by string order…
Topological phase transition in anti-symmetric Lotka-Volterra doublet chain
Rukmani Bai, Sourin Chatterjee, Ujjwal Shekhar +3
We present the emergence of topological phase transition in the minimal model of two dimensional rock-paper-scissors cycle in the form of a doublet chain. The evolutionary dynamics…
Emergence of first-order and second-order phase transitions in a cyclic ecosystem exposed to environmental impact
Sirshendu Bhattacharyya
A cyclically dominating three-species ecosystem, modeled within the framework of rock-paper-scissor game, is studied in presence of natural death and an effect of the environment.…
Signature of quantum phase transition manifested in quantum fidelity at finite temperature
Protyush Nandi, Sirshendu Bhattacharyya, Subinay Dasgupta
The signature of quantum phase transition is generally wiped out at finite temperature. A few quantities that have been observed to carry this signature through a nonanalytic behav…
Optimizing the location of the colony of foragers with Collective Learning
Sanchayan Bhowal, Ramkrishna Jyoti Samanta, Arnob Ray +2
Animal groups collaborate with one another throughout their lives to better comprehend their surroundings. Here, we try to model, using continuous random walks, how the entire proc…
Effect of mobility in the rock-paper-scissor dynamics with high mortality
Sahil Islam, Argha Mondal, Mauro Mobilia +2
In the evolutionary dynamics of a rock-paper-scissor (RPS) model, the effect of natural death plays a major role in determining the fate of the system. Coexistence, being an unstab…
Detection of quantum phase boundary at finite temperatures in integrable spin models
Protyush Nandi, Sirshendu Bhattacharyya, Subinay Dasgupta
Quantum phase transitions occur when quantum fluctuation destroys order at zero temperature. With an increase in temperature, normally the thermal fluctuation wipes out any signs o…
Mortality makes coexistence vulnerable in evolutionary game of rock-paper-scissors
Sirshendu Bhattacharyya, Pritam Sinha, Rina De +1
Multiple species in the ecosystem are believed to compete cyclically for survival and thus maintain balance in nature. Stochasticity has also an inevitable role in this dynamics. C…
Exotic signature of dynamical quantum phase transition in the time evolution of engineered initial state
Sirshendu Bhattacharyya, Subinay Dasgupta
Dynamical phase transition in quantum many body systems is usually studied by taking it in the ground state and then quenching a parameter to a new value. We investigate here the d…
Dynamics in quantum Ising chain driven by inhomogeneous transverse magnetization
Sirshendu Bhattacharyya, Subinay Dasgupta
We study the dynamics caused by transport of transverse magnetization in one dimensional transverse Ising chain at zero temperature. We observe that a class of initial states havin…
Signature of a Continuous Quantum Phase Transition in Nonequilibrium Energy Absorption: Footprints of Criticality on Highly Excited States
Sirshendu Bhattacharyya, Subinay Dasgupta, Arnab Das
Understanding phase transitions in quantum matters constitutes a significant part of present day condensed matter physics. Quantum phase transitions concern ground state properties…
Transverse Ising Chain under Periodic Instantaneous Quenches: Dynamical Many-Body Freezing and Emergence of Solitary Oscillation
Sirshendu Bhattacharyya, Arnab Das, Subinay Dasgupta
We study the real-time dynamics of a quantum Ising chain driven periodically by instantaneous quenches of the transverse field (the transverse field varying as rectangular wave sym…
