A multi-shell extension of the interacting boson model

Physics Letters B
A multi-shell extension of the simplest formulation of the interacting boson model that appends parity-conserving (2ħω) energy excitations to the non-extended theory is proffered.

Quantum simulation of spin-boson models with structured bath [PDF]

Nature Communications
The spin-boson model, involving spins interacting with a bath of quantum harmonic oscillators, is a widely used representation of open quantum systems that describe many dissipative processes in physical, chemical and biological systems.

Disentangling phase transitions and critical points in the proton–neutron interacting boson model by catastrophe theory

Physics Letters B, 2014
We introduce the basic concepts of catastrophe theory needed to derive analytically the phase diagram of the proton–neutron interacting boson model (IBM-2). Previous studies [1–3] were based on numerical solutions.

An intrinsic-state formalism for the Interacting Boson-Fermion Model with configuration mixing

Physics Letters B
In this letter, we present the intrinsic state formalism of the Interacting Boson-Fermion Model incorporating both 0p-0h and 2p-2h (regular and intruder) configurations. The framework allows to deal with the unpaired fermion in either a single-j or multi-

Characteristics of Energy States and their Calculation Using IBM-1 and IVBM of Isotones 180HF, 182W, 184Os, 186Pt [PDF]

Kirkuk Journal of Science, 2021
The positive ground-state band (GSB) of isotones for N = 108 has been calculated using the Interacting Bosons Model (IBM-1), and Interacting Vector Boson Model (IVBM), while the negative-parity band (NPB) of  , has been calculated using the (IVBM ...

Mimicking classical noise in ion channels by quantum decoherence [PDF]

Scientific Reports
The mechanism of selectivity in ion channels is still an open question in biology. Recent studies suggest that the selectivity filter may exhibit quantum coherence, which could help explain how ions are selected and conducted.
