Direct Experimental Observation of Quantum Mpemba Effect without Bath Engineering

Arijit Chatterjee, Sakil Khan, Sachin Jain +1

The quantum Mpemba effect refers to the phenomenon of a quantum system in an initial state, far away from equilibrium, relaxing much faster than a state comparatively nearer to equ…

Steady state correlation function beyond the standard weak coupling limit and consistency with KMS relation

Sakil Khan, Lokendra Singh Rathore, Sachin Jain

Thermalization of a system when interacting with a thermal bath is an interesting problem. If a system eventually reaches a thermal state in the long time limit, it's expected that…

Statistical Correlators and Tripartite Entanglement

Sakil Khan, Dipankar Home, Urbasi Sinha +1

It has recently been argued that among the various suggested measures of tripartite entanglement, the two particular measures, viz. the Concurrence Fill and the Genuine Multipartit…

Modified quantum regression theorem and consistency with Kubo-Martin-Schwinger condition

Sakil Khan, Bijay Kumar Agarwalla, Sachin Jain

We show that the long-time limit of the two-point correlation function obtained via the standard quantum regression theorem, a standard tool to compute correlation functions in ope…

Bootstrapping PT symmetric Hamiltonians

Sakil Khan, Yuv Agarwal, Devjyoti Tripathy +1

Bootstrapping in Quantum Mechanics uses positivity condition to derive the Eigenspectum. For non-hermitian systems usual positivity condition does not work. In this paper we define…

Quantum Regression theorem for multi-time correlators : A detailed analysis in the Heisenberg Picture

Sakil Khan, Bijay Kumar Agarwalla, Sachin Jain

Quantum regression theorem is a very useful result in open quantum system and extensively used for computing multi-point correlation functions. Traditionally it is derived for two-…
