Adiabatic freezing of entanglement with insertion of defects in a one-dimensional Hubbard model
Sreetama Das, Sudipto Singha Roy, Himadri Shekhar Dhar +3
We report on ground state phases of a doped one-dimensional Hubbard model, which for large onsite interactions is governed by the - Hamiltonian, where the extant entanglement…
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…
The separability versus entanglement problem
Sreetama Das, Titas Chanda, Maciej Lewenstein +3
We present a review of the problem of finding out whether a quantum state of two or more parties is entangled or separable. After a formal definition of entangled states, we presen…
