Entanglement Dynamics in Two-Qubit Open System Interacting with a Squeezed Thermal Bath via Quantum Nondemolition interaction

Subhashish Banerjee, V. Ravishankar, R. Srikanth

We analyze the dynamics of entanglement in a two-qubit system interacting with an initially squeezed thermal environment via a quantum nondemolition system-reservoir interaction, w…

Quantum phase diagram of a spin-1/2 antiferromagnetic chain with magnetic impurity

Sujit Sarkar

We present the renormalization group (RG) flow diagram of a spin-half antiferromagnetic chain with magnetic impurity and one altered link. In this two parameters (competing interac…

Length-Scale Dependent Superconductor-Insulator Quantum Phase Transition in One Dimension

Sujit Sarkar

We study the dissipation physics of one dimensional mesoscopic superconducting quantum interference device array by using the field-theoretical renormalization group method. We obs…

Effect of strong correlation on the study of renormalization group flow diagram for Kondo effect in a interacting quantum wire

Sujit Sarkar

We present the study of Kondo effect in an interacting quantum wire. We mainly emphasis the effect of strong electronic correlations in the study of renormalization group flow diag…

qubit "mirror states" for optimal quantum communication

Sreraman Muralidharan, Siddharth Karumanchi, Sakshi Jain +2

We introduce a new genuinely 2N qubit state, known as the "mirror state" with interesting entanglement properties. The well known Bell and the cluster states form a special case of…

Quantum spin pumping at fractionally quantized magnetization state for a system with competing exchange interactions

Sujit Sarkar, C. D. Hu

We study the quantum spin pumping of an antiferromagnetic spin-1/2 chain with competing exchange interactions. We show that spatially periodic potential modulated in space and time…

Symmetry-noise interplay in quantum walk on an n-cycle

Subhashish Banerjee, R. Srikanth, C. M. Chandrashekar +1

Augmenting the unitary transformation which generates a quantum walk by a generalized phase gate G is a symmetry for both noisy and noiseless quantum walk on a line, in the sense t…
