ADVOKASI SOSIAL KOMUNITAS USUT TUNTAS TERHADAP PEMENUHAN HAK KORBAN DAN KELUARGA KORBAN TRAGEDI KANJURUHAN

Social advocacy is a systematic and organized effort to influence and bring about change, by providing support and defense for the less powerful (weak) towards those who are victims of policies and injustice. One of the problems that requires social advocacy is the problem in the world of football where this incident is in the world spotlight. This research uses a qualitative method with a descriptive type. The subjects in this research are members of the thorough investigation community, people who understand the Kanjuruhan tragedy. The data collection techniques used in this research used observation, interview and documentation techniques. The techniques used in this research are data reduction and data presentation and drawing conclusions. The results of this research are the social advocacy carried out by this thorough investigation community in fulfilling the rights of victims and families of victims of the Kanjuruhan tragedy, including seeking justice in the form of peaceful actions, raising donations in the form of seeking donations on the streets and on social media, and mental health support. in the form of establishing a mental health support post in the KNPI Malang building

Collective spontaneous emission from pairs of quantum dots: long-range vs. short-range couplings

We study the spontaneous emission from a coherently delocalized exciton state in a double quantum dot as a function of the distance between the dots, focusing on the similarities and differences between the cases of radiative (long-range, dipole) and tunnel coupling between the excitons in the dots. We show that there may be no qualitative difference between the collective emission induced by these two coupling types in spite of their essentially different physical properties.Comment: 3 pages, 2 figures.

Superradiance and enhanced luminescence from ensembles of a few self-assembled quantum dots

We study the evolution of photoluminescence (PL) from homogeneous and inhomogeneous ensembles of a few coupled QDs. We discuss the relation between signals from a given QD ensemble under strong and weak excitation (full inversion and linear response regimes): A system homogeneous enough to manifest superradiant emission when strongly inverted shows a non-exponential decay of the PL signal under spatially coherent weak excitation. In an inhomogeneous ensemble the PL decay is always nearly exponential with a qualitatively different form of the time dependence in the two excitation regimes and with a higher rate under weak excitation.Comment: 5 pages, 3 figures; moderate changes and extension

Collective spontaneous emission from a system of quantum dots

We study the spontaneous emission from a regular lateral array or a randomly distributed ensemble of quantum dots under strong excitation (full inversion) conditions. We focus on the similarities and differences between the cases of random and regular arrangement of the dots and show that there is very little difference between the evolution of luminescence in these two cases, both for identical dots and for a realistically inhomogeneously broadened ensemble. This means that the enhanced emission or superradiance effect is not due to accidental clustering of pairs of dots. Moreover, we point out that observation of an enhanced emission under weak excitation does not prove that true superradiance will develop in a fully inverted system.Comment: 4 pages, 4 figures, conference "Jaszowiec" 201

Non-equilibrium physics of Rydberg lattices in the presence of noise and dissipative processes

We study the non-equilibrium dynamics of driven spin lattices in the presence of decoherence caused by either laser phase noise or strong decay. In the first case, we discriminate between correlated and uncorrelated noise and explore their effect on the mean density of Rydberg states and the full counting statistics (FCS). We find that while the mean density is almost identical in both cases, the FCS differ considerably. The main method employed is the Langevin equation (LE) but for the sake of efficiency in certain regimes, we use a Markovian master equation and Monte Carlo rate equations, respectively. In the second case, we consider dissipative systems with more general power-law interactions. We determine the phase diagram in the steady state and analyse its generation dynamics using Monte Carlo rate equations. In contrast to nearest-neighbour models, there is no transition to long-range-ordered phases for realistic interactions and resonant driving. Yet, for finite laser detunings, we show that Rydberg lattices can undergo a dissipative phase transition to a long-range-ordered antiferromagnetic (AF) phase. We identify the advantages of Monte Carlo rate equations over mean field (MF) predictions
