Lindblad driving for nonequilibrium steady
... The standard tool for describing nonequilibrium steady-state transport through a quantum system coupled to two leads with different chemical potentials is the Keldysh formalism [1]. However, when the quantum system is interacting, the treatment of interactions within the Keldysh formalism is difficu ...

Fundamental aspects of quantum Brownian motion
... we discuss some important consequences that must hold for open, dissipative quantum systems in thermal equilibrium. The issue of quantum dissipation is exemplified with the fundamental problem of a damped harmonic quantum oscillator. The role of quantum fluctuations is discussed in the context of bo ...

Spin Hamiltonians and Exchange interactions
... S might be (i) the spin of a single electron localized on an impurity in a semiconductor; (ii) the combined spin of several d electrons in a transition-metal ion (commonest case); (iii) a nuclear spin (of course this depends on the isotope) of an atom in a crystal; or (iv) the combined spin and orbi ...

As a result of this, alternative measures have been proposed, such as the logarithmic negativity [4]. It is also possible that some particular measurement scheme may result in a most na ...

Black Hole Singularities in the Framework... Gauge/String Duality by Guido Nicola Innocenzo Festuccia
... find a UV/UV connection that governs physics inside the horizon. For the case the bulk theory lives in 5 dimensions the dual theory is an SU(N) Yang-Mills theory on a sphere, a bounded many-body system. The signatures of the singularity we found are only present as N -+ oo. To elucidate the emergenc ...

Creating fractional quantum Hall states with atomic clusters
... We consider a cluster of bosonic atoms of (pseudo-)spin F , strongly confined along the spatial direction z, leading to quasi-two-dimensional (quasi-2D) dynamics in the x-y plane. An additional harmonic confinement is produced along x and y, of angular frequency ω—the trap being assumed perfectly is ...

... In order to illustrate our general framework, we will present here an explicit calculation of the σ transform of virtual Compton scattering on the quantum fluctuations of a lepton in QED at one-loop order [12], the same system which gives the Schwinger anomalous moment α/2π . This model has the adva ...
