Dissipative quantum chaos unveiled by stochastic quantum trajectories

Vincenzo Savona, Pasquale Scarlino, Fabrizio Minganti, Luca Gravina, Debbie Eeltink, Filippo Ferrari

We define quantum chaos and integrability in open quantum many-body systems as a dynamical property of single stochastic realizations, referred to as quantum trajectories. This definition relies on the predictions of random matrix theory applied to the sub ...

Drastic influence of substituent position on orientation of 2D layers enables efficient and stable 3D/2D perovskite solar cells

Mohammad Khaja Nazeeruddin, Paul Joseph Dyson, Andreas Züttel, Hiroyuki Kanda, Liping Zhong, Xiaoxin Gao, Ümmügülsüm Günes

The lack of long-term stability and reproducibility of perovskite solar cells (PSCs) is the main roadblock preventing their successful commercialization. 3D/2D PSCs are one of the most prominent ways to address these issues. Various salts that are mostly b ...

Additives-free indolo[3,2-b]carbazole-based hole-transporting materials for perovskite solar cells with three yeses: Stability, efficiency, simplicity

Ulf Anders Hagfeldt, Bowen Yang, Jiajia Suo, Yeonju Kim

Indolo[3,2-b]carbazole-based hole transporting materials (HTM1-3) are developed for dopant-free pemvskite solar cells (PSCs). The newly synthesized compounds are studied as alternatives of conventional hole-transporting materials which typically require ad ...

Ultralong Charge Carrier Recombination Time in Methylammonium Lead Halide Perovskites

László Forró, Andrzej Sienkiewicz, Márton Kollár, Ferenc Simon

Due to their exceptional photovoltaic properties, metal halide perovskites (MHPs) are extensively studied for their potential applications in solar cells. In recent years, the power conversion efficiencies of MHPs-based solar cells rapidly increased from t ...

Evolution of the Primordial Axial Charge across Cosmic Times

Oleksandr Sobol

We investigate collisional decay of the axial charge in an electron-photon plasma at temperatures 10 MeV-100 GeV. We demonstrate that the decay rate of the axial charge is first order in the fine-structure constant Gamma(flip) proportional to am(e)(2)/T an ...

Nonlinear kinetic simulation study of the ion-ion streaming instability in single- and multi-ion species plasmas

Stephan Brunner

The nonlinear evolution of the ion-ion streaming instability (IISI) is studied using numerical techniques novel to this problem that afford direct insight into the evolution of the particle distributions of each species. During the linear phase of the inst ...

Iterative Unbiasing of Quasi-Equilibrium Sampling

Michele Ceriotti, Bingqing Cheng, Federico Giberti

Atomistic modeling of phase transitions, chemical reactions, or other rare events that involve overcoming high free energy barriers usually entails prohibitively long simulation times. Introducing a bias potential as a function of an appropriately chosen s ...
