We revisit the problem of the deformed oscillator with position-dependent mass [da Costa et
al., J. Math. Phys. 62, 092101 (2021)] in the classical and quantum formalisms by …

The effect of nonlinearity, initial atomic state, and different resonance cases on the
interaction between nonlinear SU (1, 1) quantum states and a two-level atom is discussed …

We develop generalized coherent states based on the Gazeau–Klauder formalism for a
particle with position-dependent mass trapped in an infinite square well. We study the …

Using ladder operators for the non-linear oscillator with position-dependent effective mass,
realization of the dynamic group SU (1, 1) is presented. Keeping in view the algebraic …

We develop generalized coherent states for a class of nonlinear oscillators with position-
dependent effective mass in the context of the Gazeau–Klauder formalism and discuss some …

A generalized scheme for the construction of coherent states in the context of position-
dependent effective mass systems has been presented. This formalism is based on the …

We explore two coupled dipole qubits interacting with two-mode cavity fields through non-
degenerate two-photon processes and under the influence of intrinsic noise. Our …

We generalize the technique called as the integration within a normally ordered product
(IWOP) of operators referring to the creation and annihilation operators of the harmonic …

In this paper, we study a Hamiltonian system constituted by two coupled two-level atoms
(qubits) interacting with a nonlinear generalized cavity field. The nonclassical two-qubit …

In this manuscript we consider q-deformed boson algebra by using the Tsallis' sq-deformed
exponential which arises in the non-extensive thermodynamics. Using this we construct q …
