Benford analysis of quantum critical phenomena: First digit provides high finite-size scaling exponent while first two and further are not much better
Anindita Bera, Utkarsh Mishra, Sudipto Singha Roy +3
Benford's law is an empirical edict stating that the lower digits appear more often than higher ones as the first few significant digits in statistics of natural phenomena and math…
Phase boundaries in alternating field quantum XY model with Dzyaloshinskii-Moriya interaction: Sustainable entanglement in dynamics
Saptarshi Roy, Titas Chanda, Tamoghna Das +3
We report all phases and corresponding critical lines of the quantum anisotropic transverse XY model with Dzyaloshinskii-Moriya (DM) interaction along with uniform and alternating…
Deterministic Quantum Dense Coding Networks
Saptarshi Roy, Titas Chanda, Tamoghna Das +2
We consider the scenario of deterministic classical information transmission between multiple senders and a single receiver, when they a priori share a multipartite quantum state -…
Emergence of entanglement with temperature and time in factorization-surface states
Titas Chanda, Tamoghna Das, Debasis Sadhukhan +3
There exist zero-temperature states in quantum many-body systems that are fully factorized, thereby possessing vanishing entanglement, and hence being of no use as resource in quan…
Wave-particle duality employing quantum coherence in superposition with non-orthogonal pointers
Sreetama Das, Chiranjib Mukhopadhyay, Sudipto Singha Roy +3
We propose the notion of quantum coherence for superpositions over states which are not necessarily mutually orthogonal. This anticipatedly leads to a resource theory of non-orthog…
