Quantum Langevin dynamics and the long-time behaviour of two charged coupled oscillators in a common heat bath
Koushik Mandal, Suraka Bhattacharjee
In this paper, the moderately long-time behaviours of the correlation functions for two charged coupled harmonic oscillators connected to a common heat bath are analyzed in the pre…
Decoherence and the ultraviolet cutoff: non-Markovian dynamics of a charged particle in a magnetic field
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
We derive a non-Markovian master equation for a charged particle in a magnetic field coupled to a bath and study decoherence by analysing the temporal decay of the off-diagonal ele…
Atomic Inversion and Entanglement Dynamics for Squeezed Coherent Thermal States in the Jaynes-Cummings Model
Koushik Mandal, M. V. Satyanarayana
The tussling interplay between the thermal photons and the squeezed photons is discussed. The `classical noise' is represented by the thermal photons and the `quantum noise' is rep…
Quantum Langevin Equation of a spin in a magnetic field : an analysis
Suraka Bhattacharjee, Koushik Mandal, Supurna Sinha
We derive a quantum Langevin equation for a quantum spin in the presence of a magnetic field and study its dynamics in the Markovian limit using the Ohmic bath model. We extend our…
Some aspects of Microscopic Mechanism of Superconductivity in conventional and non-conventional systems
Ranjan Chaudhury, Koushik Mandal
A broad review of theoretical research work involving different types of microscopic mechanism in various classes of superconductors, carried out in our research group over a decad…
A Theoretical Analysis of Superconducting Pairing in Correlated Metallic Systems
Koushik Mandal, Ranjan Chaudhury
We have introduced a Coulomb correlated normal state to study the superconducting pairing with a Fermi liquid like normal phase background in a 3 dimensional system. The role of th…
Atomic and entanglement dynamics in the mixed squeezed coherent state version of the Jaynes-Cummings interaction
Koushik Mandal, Pooja Jethwani, M. Venkata Satyanarayana
Coherent signal containing squeezed noise in a mixed state of radiation field is considered here as a non-Gaussian mixture of a coherent state density operator and a squeezed state…
Interplay of Pairing Correlation and Coulomb Correlation in Boson Exchange Superconductors
Koushik Mandal, Ranjan Chaudhury
A theoretical methodology for exploring the conventional Bardeen-Cooper-Schrieffer (BCS) pairing instability for superconductivity from a correlated normal phase for all possible d…
A novel application of Fiber Bragg Grating (FBG) sensors in MPGD
D. Abbaneo, M. Abbas, M. Abbrescia +153
We present a novel application of Fiber Bragg Grating (FBG) sensors in the construction and characterisation of Micro Pattern Gaseous Detector (MPGD), with particular attention to…
Fiber Bragg Grating (FBG) sensors as flatness and mechanical stretching sensors
D. Abbaneo, M. Abbas, M. Abbrescia +153
A novel approach which uses Fibre Bragg Grating (FBG) sensors has been utilised to assess and monitor the flatness of Gaseous Electron Multipliers (GEM) foils. The setup layout and…
Performance of a Large-Area GEM Detector Prototype for the Upgrade of the CMS Muon Endcap System
D. Abbaneo, M. Abbas, M. Abbrescia +134
Gas Electron Multiplier (GEM) technology is being considered for the forward muon upgrade of the CMS experiment in Phase 2 of the CERN LHC. Its first implementation is planned for…
