Exotic correlation spread in free-fermionic states with initial patterns
Sudipto Singha Roy, Giovanni Ramírez, Silvia N. Santalla +2
We describe a relation between the light-cone velocities after a quantum quench and the internal structure of the initial state, in the particular case of free fermions on a chain…
Link representation of the entanglement entropies for all bipartitions
Sudipto Singha Roy, Silvia N. Santalla, Germán Sierra +1
We have recently shown that the entanglement entropy of any bipartition of a quantum state can be approximated as the sum of certain link strengths connecting internal and external…
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…
Quantum discord and its allies: a review
Anindita Bera, Tamoghna Das, Debasis Sadhukhan +3
We review concepts and methods associated with quantum discord and related topics. We also describe their possible connections with other aspects of quantum information and beyond,…
