چکیده

The purpose of this work is to understand the effect of an external environment on the adiabatic dynamics of a quantum critical system. By means of scaling arguments we derive a general expression for the density of excitations produced in the quench as a function of its velocity and of the temperature of the bath. We corroborate the scaling analysis by explicitly solving the case of a one-dimensional quantum Ising model coupled to an Ohmic bath.

Characterizing the energy gap and demonstrating an adiabatic quench in an interacting spin system

Spontaneous symmetry breaking occurs in a physical system whenever the ground state does not share the symmetry of the underlying theory, e.g., the Hamiltonian [1, 2]. It gives rise to massless Nambu-Goldstone modes [1, 3] and massive Anderson-Higgs modes [4, 5]. These modes provide a fundamental understanding of matter in the Universe and appear as collective phase/amplitude excitations of an ...

Non-adiabatic quantum molecular dynamics: Ionization of many electron systems

Abstract We propose a novel method to describe realistically ionization processes with absorbing boundary conditions in basis expansion within the formalism of the so-called Non-Adiabatic Quantum Molecular Dynamics. This theory couples self-consistently a classical description of the nuclei with a quantum mechanical treatment of the electrons in atomic many-body systems. In this paper we extend...

Time-dependent density functional theory of open quantum systems in the linear-response regime.

Time-dependent density functional theory (TDDFT) has recently been extended to describe many-body open quantum systems evolving under nonunitary dynamics according to a quantum master equation. In the master equation approach, electronic excitation spectra are broadened and shifted due to relaxation and dephasing of the electronic degrees of freedom by the surrounding environment. In this paper...
