Designing refrigerators in higher dimensions using quantum spin models
Tanoy Kanti Konar, Srijon Ghosh, Amit Kumar Pal +1
We design quantum refrigerators based on spin-j quantum XYZ and bilinear-biquadratic models with individual spins attached to bosonic thermal baths. By considering both local and g…
Circulating Genuine Multiparty Entanglement in Quantum Network
Pritam Halder, Ratul Banerjee, Srijon Ghosh +2
We propose a deterministic scheme of generating genuine multiparty entangled states in quantum networks of arbitrary size having various geometric structures -- we refer to it as e…
Quantum Battery with Ultracold Atoms: Bosons vs. Fermions
Tanoy Kanti Konar, Leela Ganesh Chandra Lakkaraju, Srijon Ghosh +1
We design a quantum battery made up of bosons or fermions in an ultracold-atom setup, described by Fermi-Hubbard and Bose-Hubbard models, respectively. We compare the performance o…
Necessary condition for information transfer under simulated parity-time-symmetric evolution
Leela Ganesh Chandra Lakkaraju, Shiladitya Mal, Aditi Sen De
Parity-time (PT) symmetric quantum theory can broaden the scope of quantum dynamics beyond unitary evolution which may lead to numerous counter-intuitive phenomena, including singl…
