Quest for optimal quantum resetting: Protocols for a particle on a chain

P Chatterjee, S Aravinda, R Modak - Physical Review E, 2024 - APS
In the classical context, it is well known that, sometimes, if a search does not find its target, it
is better to start the process anew. This is known as resetting. The quantum counterpart of …

Engineering skin effect across a junction of Hermitian and non-Hermitian lattice

R Modak - arXiv preprint arXiv:2308.05702, 2023 - arxiv.org
We study a system where the two edges of a non-Hermitian lattice with asymmetric nearest-
neighbor hopping are connected with two Hermitian lattices with symmetric nearest …

Complexity growth for one-dimensional free-fermionic lattice models

S Aravinda, R Modak - Physical Review B, 2023 - APS
Complexity plays a very important part in quantum computing and simulation where it acts
as a measure of the minimal number of gates that are required to implement a unitary circuit …

Quest for optimal quantum resetting protocols

P Chatterjee, S Aravinda, R Modak - arXiv preprint arXiv:2311.09150, 2023 - arxiv.org
In the classical context, it is well known that, sometimes, if the search does not find its target,
it is better to start the process anew again, known as resetting. The quantum counterpart of …

Probing quantum phase transitions via quantum speed limits

M Suman, S Aravinda, R Modak - Physical Review A, 2024 - APS
The quantum speed limit (QSL) is the lower bound on the time required for a state to evolve
to a desired final state under a given Hamiltonian evolution. Three well-known QSLs exist …

Solitons in Quasiperiodic Lattices with Fractional Diffraction

E Pavlyshynets, L Salasnich, BA Malomed… - arXiv preprint arXiv …, 2024 - arxiv.org
We study the dynamics of solitons under the action of one-dimensional quasiperiodic lattice
potentials, fractional diffraction, and nonlinearity. The formation and stability of the solitons is …
