Carbon Energy, EarlyView.By modifying wide‐bandgap high‐Cs perovskite surfaces with quaternary ammonium salts of varying alkyl‐chain lengths, tetrapropylammonium bromide (TPABr) is shown to successfully construct a 1D/3D heterojunction. This structure effectively passivates interface defects and optimizes energy level alignment, achieving a champion efficiency of 20.14% with ...

Geometric squeezing of rotating quantum gases into the lowest Landau level
Comptes Rendus. PhysiqueThe simulation of quantum Hall physics with rotating quantum gases is witnessing a revival due to recent experimental advances that enabled the observation of a Bose–Einstein condensate entirely contained in its lowest kinetic energy state, i.e.

Quantum geometrodynamics revived I. Classical constraint algebra
Classical and Quantum GravityAbstract In this series of papers, we present a set of methods to revive quantum geometrodynamics which encountered numerous mathematical and conceptual challenges in its original form promoted by Wheeler and De Witt. In this paper, we introduce the regularization scheme on which we base the subsequent quantization and continuum limit of

Quenching the Hubbard Model: Comparison of Nonequilibrium Green's Function Methods
Contributions to Plasma Physics, EarlyView.ABSTRACT We benchmark nonequilibrium Green's function (NEGF) approaches for interaction quenches in the half‐filled Fermi–Hubbard model in one and two dimensions. We compare fully self‐consistent two‐time Kadanoff–Baym equations (KBE), the generalized Kadanoff–Baym ansatz (GKBA), and the recently developed NEGF‐based quantum fluctuations approach (NEGF‐

Classification of Quench Dynamical Behaviours in Spinor Condensates [PDF]
, 2017 Thermalization of isolated quantum systems is a long-standing fundamental problem where different mechanisms are proposed over time. We contribute to this discussion by classifying the diverse quench dynamical behaviours of spin-1 Bose-Einstein ...

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.Coordinated engineering of the anode, electrolyte, and interface underpins the rational design of next‐generation solid‐state metal‐sulfur batteries. Solid‐state metal‐sulfur batteries are emerging as a transformative energy storage platform with the potential to overcome the fundamental limitations of conventional flooded cells, particularly ...

Overcoming decoherence in the collapse and revival of spin Schr\"odinger cats
, 2012 In addition to being a very interesting quantum phenomenon, Schr\"odinger cat swapping has the potential for application in the preparation of quantum states that could be used in metrology and other quantum processing.

Dynamics of Quantum Coherence and Quantum Fisher Information After Sudden Quench
, 2020 The dynamics of relative entropy and $l_{1}$-norm of coherence, as well as, the Wigner-Yanase-skew and quantum Fisher information are studied for a time-dependent coupled XY spin chain in presence of a time-dependent transverse magnetic field ...
