Dynamics of entanglement in a two-mode nonlinear Jaynes-Cummings mode
A B M Ahmed, S Sivakumar
Dynamics of entanglement due to intensity-dependent interaction between a two-level atom and a single-mode electromagnetic field in a Kerr medium is studied. The form of the intera…
Regional versus Global Entanglement in Resonating-Valence-Bond states
Anushya Chandran, Dagomir Kaszlikowski, Aditi Sen De +2
We investigate the entanglement properties of resonating-valence-bond states on two and higher dimensional lattices, which play a significant role in our understanding of various m…
Entanglement, avoided crossings and quantum chaos in an Ising model with a tilted magnetic field
J. Karthik, Auditya Sharma, Arul Lakshminarayan
We study a one-dimensional Ising model with a magnetic field and show that tilting the field induces a transition to quantum chaos. We explore the stationary states of this Hamilto…
Quantum chaos in the spectrum of operators used in Shor's algorithm
Krishnendu Maity, Arul Lakshminarayan
We provide compelling evidence for the presence of quantum chaos in the unitary part of Shor's factoring algorithm. In particular we analyze the spectrum of this part after proper…
Wave packet dynamics of entangled two-mode states
C. Sudheesh, S. Lakshmibala, V. Balakrishnan
We consider a model Hamiltonian describing the interaction of a single-mode radiation field with the atoms of a nonlinear medium, and study the dynamics of entanglement for specifi…
Non-classical properties of quantum wave packets propagating in a Kerr-like medium
C. Sudheesh, S. Lakshmibala, V. Balakrishnan
We investigate non-classical effects such as fractional revivals, squeezing and higher-order squeezing of photon-added coherent states propagating through a Kerr-like medium.The Wi…
