Steady States of Infinite-Size Dissipative Quantum Chains via Imaginary Time Evolution

Directly in the thermodynamic limit, we show how to combine imaginary and real time evolution of tensor networks to efficiently and accurately find the nonequilibrium steady states (NESS) of one-dimensional dissipative quantum lattices governed by the Lindblad master equation. The imaginary time evolution first bypasses any highly correlated portions of the real-time evolution trajectory by directly converging to the weakly correlated subspace of the NESS, after which real time evolution completes the convergence to the NESS with high accuracy. We demonstrate the power of the method with the dissipative transverse field quantum Ising chain. We show that a crossover of an order parameter shown to be smooth in previous finite-size studies remains smooth in the thermodynamic limit.Comment: 5+3 pages, 5 figures, 2 table

Symmetry between repulsive and attractive interactions in driven-dissipative Bose-Hubbard systems

The driven-dissipative Bose-Hubbard model can be experimentally realized with either negative or positive onsite detunings, inter-site hopping energies, and onsite interaction energies. Here we use one-dimensional matrix product density operators to perform a fully quantum investigation of the dependence of the non-equilibrium steady states of this model on the signs of these parameters. Due to a symmetry in the Lindblad master equation, we find that simultaneously changing the sign of the interaction energies, hopping energies, and chemical potentials leaves the local boson number distribution and inter-site number correlations invariant, and the steady-state complex conjugated. This shows that all driven-dissipative phenomena of interacting bosons described by the Lindblad master equation, such as "fermionization" and "superbunching", can equivalently occur with attractive or repulsive interactions.Comment: single column 12 pages, 4 figures, 1 tabl

Rekonstruksi Perlindungan Hak-hak Korban Tindak Pidana

Victims as the suffred person because of crime, should receive the protection of their rights. Indonesian positive law (Penal Code and Criminal Procedure Code) was originally regulated only compensation to victims. Then, victims\u27 rights later evolved to become more widespread in Law No. 13 of 2006 on the protection of witnesses and victims. However, the protection of victims\u27 rights is not integrated to the criminal justice system. Therefore, the reconstruction of the protection of rights of victims was taken so that all victims can obtain the widest possible access to their rights. Keywords: Victims\u27 Rights and Laws Protection Korban sebagai pihak yang menderita akibat suatu tindak pidana, perlu mendapat perlindungan hukum terhadap hak-haknya. Hukum positif Indonesia (KUHP dan KUHAP) pada awalnya hanya memberikan hak ganti rugi terhadap korban. Hak-hak korban kemudian berkembang menjadi lebih luas dalam undang-undang nomor 13 tahun 2006 tentang perlindungan saksi dan korban. Namun, perlindungan hak-hak korban dalam undang-undang tersebut tidak terintegrasi dalam jaringan sistem peradilan pidana. Rekonstruksi perlindungan hak-hak korban dilakukan supaya semua korban dapat memperoleh akses seluas-luasnya atas hak-hakny

Collisional Energy Loss of Non Asymptotic Jets in a QGP

We calculate the collisional energy loss suffered by a heavy (charm) quark created at a finite time within a Quark Gluon Plasma (QGP) in the classical linear response formalism as in Peigne {\it et al.} \cite{peigne}. We pay close attention to the problem of formulating a suitable current and the isolation of binding and radiative energy loss effects. We find that unrealistic large binding effects arising in previous formulations must be subtracted. The finite time correction is shown to be important only for very short length scales on the order of a Debye length. The overall energy loss is similar in magnitude to the energy loss suffered by a charge created in the asymptotic past. This result has significant implications for the relative contribution to energy loss from collisional and radiative sources and has important ramifications for the ``single electron puzzle'' at RHIC.Comment: 15 Pages, 11 figures, revte
