Abstract

Employing quadratic fermionic and bosonic Hamiltonians for collective and internal subsystems with a linear rotating-wave-approximation coupling, we studied the role of heat-bath statistics on the dynamics of the collective motion. The master equations for the collective occupation number derived directly from the quadratic Hamiltonians and within the Non-Markovian Langevin approach are discussed and their solutions are obtained. Because of the different nature of the heat-bath statistics, the path to equilibrium or the relaxation time is affected as shown in the numerical calculations.

Employing the fermionic and bosonic Hamiltonians for the collective oscillator linearly FC-coupled with several heat baths, the analytical expressions for the collective occupation number are derived within the non-Markovian quantum Langevin approach. The master equations for the occupation number of collective subsystem are derived and discussed. In the case of Ohmic dissipation with Lorenzian cutoffs, the possibility of reduction of the system with several heat baths to the system with one heat bath is analytically demonstrated. For the fermionic and bosonic systems, a comparative analysis is performed between the collective subsystem coupled to two heat baths and the reference case of the subsystem coupled to one bath.

For the fermionic or bosonic oscillator fully coupled to several heat baths with mixed statistics, the analytical expressions for the occupation numbers are derived within the non-Markovian quantum Langevin approach. Employing two or three heat baths and the Ohmic dissipation with Lorenzian cutoffs, the role of statistics of the system and heat baths in the dynamics of the system is studied.

Non-Markovian dynamics with fermions

Vazgen Valerikovich Sargsyan, G. G. Adamian, N. V. Antonenko +1 more

Employing the quadratic fermionic Hamiltonians for the collective and internal subsystems with a linear coupling, we studied the role of fermionic statistics on the dynamics of the collective motion. The transport coefficients are discussed as well as the associated fluctuation-dissipation relation. Due to different nature of the particles, the path to equilibrium is slightly affected. However, in the weak-coupling regime, the time scale for approaching equilibrium is found to be globally unchanged. The Pauli-blocking effect can modify the usual picture in open quantum system. In some limits, contrary to boson, this effect can strongly hinder the influence of the bath by blocking the interacting channels.

Non-Markovian dynamics of fully coupled fermionic and bosonic oscillators

Vazgen Valerikovich Sargsyan, Denis Lacroix A, G. G. Adamian +1 more

The non-Markovian Langevin approach is applied to study the dynamics of fermionic (bosonic) oscillator linearly coupled to a fermionic (bosonic) environment. The analytical expressions for occupation numbers in two different types of couplings (rotating-wave approximation and fully coupled) are compared and discussed. The weak-coupling and high- and low-temperature limits are considered as well. The conditions under which the environment imposes its thermal equilibrium on the collective subsystem are discussed. The sameness of the results, obtained with both the Langevin approach and the discretized environment method are shown. Short- and long-time nonequilibrium dynamics of fermionic and bosonic open quantum systems are analyzed both analytically and numerically.

Non-Markovian modeling of Fermi-Bose systems coupled to one or several Fermi-Bose thermal baths

Denis Lacroix A, Vazgen Valerikovich Sargsyan, G. G. Adamian +2 more

A method is proposed to describe Fermi or Bose systems coupled to one or several heat baths composed of fermions and/or bosons. The method, called the coupled equations of motion method, properly includes non-Markovian effects. The approach is exact in the full-coupling approximation when only bosonic particles are present in the system and baths. The approach provides an approximate treatment when fermions are present either in the system and/or in one or several environments. Our approach has the advantage of properly respecting the Pauli exclusion principle for fermions during the evolution. We illustrate the approach for the single fermionic or bosonic oscillator coupled to one or two heat baths assuming different types of quantum statistics (fermion or boson) for them. The cases of a Fermi system coupled to fermion or boson heat baths or a mixture of both are analyzed in detail. With the future goal of treating Fermi systems formed of an increasing number of two-level systems (qubits), we discuss possible simplifications that could be made in the equations of motion and their limits of validity in terms of the system-bath coupling or of the initial heat bath temperatures.

Dynamics and thermalization of a fermion in a fermionic bath embedded in a bosonic bath.

Michael. Mwalaba

We consider a model consisting of a finite number of quantum dots each of which confines a spinless electron. We zoom in on a single quantum dot containing an electron of interest treating it as being strongly coupled to the surrounding finite bath of electrons. The fermionic bath is embedded in a bosonic Markovian bath. The master equation for the fermion of interest interacting with the fermionic bath is derived. Based on the master equation for this system, the reduced dynamics and thermalization of the spinless electron is studied. We start with a description of the Hamiltonian of the entire system which we call total Hamiltonian. Because the electron of interest is strongly coupled to the surrounding fermionic bath, we treat the Hamiltonian consisting of the electron of interest, the fermionic bath and the interaction between them as the system Hamiltonian. Then using techniques of linear algebra, we diagolize the system Hamiltonian making it appear in what we are calling quasi-fermionic picture. After this, we take the diagonalized system Hamiltonian back to the total Hamiltonian. We then use this total Hamiltonian to switch to the interaction picture. Since the general expression of the Markovian quantum master equation is in terms of the interaction Hamiltonian, we now substitute our interaction Hamiltonian into it and begin from there to derive the quantum master equation of our system. In the next step, we solve the derived quantum master equation casting the solution in Kraus representation. Using the explicit form of the Kraus operators and initial conditions, the density matrix of the reduced system is obtained in the quasifermionic picture. We then transform to the original fermionic picture and trace out the fermionic bath coming out with the density matrix of the electron of interest. We then check the normalization of the density matrix of the electron of interest by calculating the trace and then use it to calculate the mean number of fermions. The mean number of fermions is then plotted against time for different coupling strengths and varying numbers of fermions in the fermionic bath to visually check the dynamics and thermalization of the fermion of interest.
