Entanglement concentration via measurement:- role of imaginarity
Indranil Biswas, Subrata Bera, Ujjwal Sen +2
The role of complex numbers in quantum theory extends beyond mathematical convenience, having recently been formalized as a resource under the framework of the resource theory of i…
Discrete time crystal order in spin chains enabled by Floquet flat bands
Mahbub Rahaman, Analabha Roy
We propose a novel protocol to realize discrete time-crystal (DTC) order in clean, periodically driven spin- chains. In each drive cycle, a global spin flip is followed by a t…
Galaxy evolution in the cosmic web: the relative impact of nodes and filaments in the EAGLE simulation
Suman Sarkar, Biswajit Pandey, Apashanka Das
Galaxies evolve within the intricate geometry of the cosmic web, yet the distinct roles of its primary components - nodes and filaments remain incompletely understood. Using the EA…
Ergotropic Mpemba crossings in finite-dimensional quantum batteries
Triyas Sapui, Tanoy Kanti Konar, Aditi Sen De
The quantum Mpemba effect is a counterintuitive phenomenon in which a state initially farther from equilibrium relaxes more rapidly than one that starts nearer to equilibrium. In t…
Protocols for sharing genuine multipartite entanglement by employing copies of biseparable states
Swati Choudhary, Ujjwal Sen, Saronath Halder
Sharing genuine multipartite entanglement by considering collective use of copies of biseparable states, which are entangled across all bipartitions but lack genuine multipartite e…
Localization from Infinitesimal Kinetic Grading: Finite-size Scaling, Kibble-Zurek Dynamics and Applications in Sensing
Argha Debnath, Ayan Sahoo, Debraj Rakshit
We study a one-dimensional lattice model with site-dependent nearest-neighbor hopping amplitudes that follow a power-law profile. The hopping variation is controlled by a grading e…
