Some Studies On Exact Solutions Of Models In Noncommutative Spaces
Manjari Dutta
The central theme of my thesis is to explore various simple prototype models that are exactly solvable in the framework of time dependent noncommutative spaces. By adopting the met…
Quantum regression theorem in the Unruh-DeWitt battery
Manjari Dutta, Arnab Mukherjee, Sunandan Gangopadhyay
In this paper, we employ the quantum regression theorem, a powerful tool in the study of open quantum systems, to analytically study the correlation functions of an Unruh-DeWitt de…
Quasi-normal modes of quantum gravity black hole with perfectly fluid dark matter
Arpita Jana, Manjari Dutta, Sunandan Gangopadhyay
In this work, we have studied the motion of a massless scalar photon in the renormalization group (RG) improved Schwarzschild black hole spacetime in the presence of perfectly flui…
Density matrix analysis of systems influenced by periodic Hamiltonians
Soham Sen, Manjari Dutta, Sunandan Gangopadhyay
In this work, we consider simple systems that are influenced by Hamiltonians with time periodicity. Our analysis is mainly focussed on the density matrix approach and aims to solve…
Area spectrum and black hole thermodynamics
Arpita Jana, Manjari Dutta, Sunandan Gangopadhyay
The role of horizon area quantization on black hole thermodynamics is investigated in this article. The coefficient appearing in the quantization of area is fixed by an appeal to t…
Quantum harmonic oscillator in a time dependent noncommutative background
Manjari Dutta, Shreemoyee Ganguly, Sunandan Gangopadhyay
This work explores the behaviour of a noncommutative harmonic oscillator in a time-dependent background, as previously investigated in [1]. Specifically, we examine the system when…
Lewis and Berry phases for a gravitational wave interacting with a quantum harmonic oscillator
Soham Sen, Manjari Dutta, Sunandan Gangopadhyay
In this work, we consider a gravitational wave interacting with a quantum harmonic oscillator in the transverse-traceless gauge. We take the gravitational wave to be carrying the s…
Exact solution of damped harmonic oscillator with a magnetic field in a time dependent noncommutative space
Manjari Dutta, Shreemoyee Ganguly, Sunandan Gangopadhyay
In this paper we have obtained the exact eigenstates of a two dimensional damped harmonic oscillator in the presence of an external magnetic field varying with respect to time in t…
Exact solutions of a damped harmonic oscillator in a time dependent noncommutative space
Manjari Dutta, Shreemoyee Ganguly, Sunandan Gangopadhyay
In this paper we have obtained the exact eigenstates of a two dimensional damped harmonic oscillator in time dependent noncommutative space. It has been observed that for some spec…
Photon velocity, power spectrum in Unruh effect with modified dispersion relation
Arnab Mukherjee, Sunandan Gangopadhyay, Manjari Dutta
In this paper we propose a new form of generalized uncertainty principle which involves both a linear as well as a quadratic term in the momentum. From this we have obtained the co…
