Mechanisms of scrambling and unscrambling of quantum information in the ground state in spin chains: domain-walls, spin-flips and scattering phase shifts
Samudra Sur, Diptiman Sen
The spatiotemporal evolution of the out-of-time-order correlator (OTOC) measures the propagation and scrambling of local quantum information. For the transverse field Ising model w…

Field theoretical study of a spin-1/2 ladder with unequal chain exchanges
Sujit Sarkar, Diptiman Sen
We study the low-energy properties of a Heisenberg spin-1/2 zigzag ladder with different exchange constants on the two chains. Using a nonlinear sigma-model field theory and abelia…

Transport through quasi-ballistic quantum wires: the role of contacts
Siddhartha Lal, Sumathi Rao, Diptiman Sen
We model one-dimensional transport through each open channel of a quantum wire by a Luttinger liquid with three different interaction parameters for the leads, the contact regions…
