Beyond Integrability Preserving Renormalization-Group Protocol in Non-Hermitian Hamiltonians with Time-Dependent Interaction Strengths
Parameshwar R. Pasnoori
It is well established that in time-dependent quantum systems, integrability preserving time-dependent interaction strengths are identical to the renormalization group (RG) traject…
Exact many-body wavefunction of the Kondo model with time-dependent interaction strength
Parameshwar R. Pasnoori, Emil. A. Yuzbashyan
Quantum integrabilty has been applied to a large variety of low dimesional Hamiltonians in Quantum Field Theory, Condensed Matter Physics, and Statistical Mechanics to obtain exact…
Time-Dependent Dynamical Dimensional Transmutation in the Gross-Neveu Model with Time-Dependent Interaction Strength
Parameshwar R. Pasnoori
In this work we study driven Gross-Neveu (GN) model whose time-dependent interaction strength is constrained by quantum integrability within the recently developed generali…
Dissipation driven phase transition in the non-Hermitian Kondo model
Pradip Kattel, Abay Zhakenov, Parameshwar R. Pasnoori +2
Non-Hermitian Hamiltonians capture several aspects of open quantum systems, such as dissipation of energy and non-unitary evolution. An example is an optical lattice where the inel…
Quantum Integrability of Hamiltonians with Time-Dependent Interaction Strengths and the Renormalization Group Flow
Parameshwar R. Pasnoori
In this paper we consider quantum Hamiltonians with time-dependent interaction strengths, and following the recently formulated generalized Bethe ansatz framework [P. R. Pasnoori,…
Quantum Knizhnik-Zamolodchikov Equations and Integrability of Quantum Field Theories with Time-dependent Interaction Strength
Parameshwar R. Pasnoori
In this paper we consider the problem of solving quantum field theories with time dependent interaction strengths. We show that the recently formulated framework [P. R. Pasnoori, P…
