Cosmological Correlators Using Tensor Networks
Ujjwal Basumatary, Aninda Sinha, Xinan Zhou
We develop a nonperturbative tensor-network framework for computing cosmological correlators in de Sitter space and use it to test the proposal that suitably defined in-in correlat…

Lectures on Quantum Field Theory on a Quantum Computer
Aninda Sinha, Ujjwal Basumatary
The lecture notes cover the basics of quantum computing methods for quantum field theory applications. No detailed knowledge of either quantum computing or quantum field theory is…

Beyond Hawking evaporation of black holes formed by dark matter in compact stars
Ujjwal Basumatary, Nirmal Raj, Anupam Ray
The memory burden effect is an explicit resolution to the information paradox by which an evaporating black hole acquires quantum hair, which then suppresses its rate of mass loss…
