Fibonacci sequence and its generalizations in doped quantum spin ladders
Sudipto Singha Roy, Himadri Shekhar Dhar, Aditi Sen De +1
An interesting aspect of antiferromagnetic quantum spin ladders, with complete dimer coverings, is that the wave function can be recursively generated by estimating the number of c…

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…
