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-…
