Transport and spectral properties of the XXXXZ diode and stability to dephasing
Kang Hao Lee, Vinitha Balachandran, Chu Guo +1
We study the transport and spectral property of a segmented diode formed by an XX XXZ spin chain. This system has been shown to become an ideal rectifier for spin current for l…
Thermopower in a boundary driven bosonic ladder in the presence of a gauge field
Bo Xing, Xiansong Xu, Vinitha Balachandran +1
We consider a bosonic two-legged ladder whose two-band energy spectrum can be tuned in the presence of a uniform gauge field, to four distinct scenarios: degenerate or non-degenera…
From ETH to algebraic relaxation of OTOCs in systems with conserved quantities
Vinitha Balachandran, Giuliano Benenti, Giulio Casati +1
The relaxation of out-of-time-ordered correlators (OTOCs) has been studied as a mean to characterize the scrambling properties of a quantum system. We show that the presence of loc…
Giant rectification in segmented, strongly interacting, spin chains despite the presence of perturbations
Kang Hao Lee, Vinitha Balachandran, Dario Poletti
In Phys. Rev. Lett. 120, 200603 (2018), a segmented XXZ spin chain with zero anisotropy in one half and a large anisotropy on the other half gave rise to a spin current rectificati…
