Tunable Quantum Fluctuation-Controlled Coherent Spin Dynamics

, 2008
Temporal evolution of a macroscopic condensate of ultra cold atoms is usually driven by mean field potentials, either due to scattering between atoms or due to coupling to external fields; and coherent quantum dynamics have been observed in various cold ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

Advanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Quantum jumps are more quantum than quantum diffusion

New Journal of Physics, 2014
It was recently argued (Wiseman and Gambetta 2012 Phys. Rev. Lett. http://dx.doi.org/10.1103/PhysRevLett.108.220402 108 http://dx.doi.org/10.1103/PhysRevLett.108.220402 ) that the stochastic dynamics (jumps or diffusion) of an open quantum system are not

Improving the oxygen redox reversibility of Li-rich battery cathode materials via Coulombic repulsive interactions strategy

Nature Communications, 2022
Tailoring the oxygen redox reactivity in Li-rich cathode is crucial for developing high-energy batteries. Here, the authors report a strategy to obtain a flexible crystal structure and enhance the oxygen redox reversibility.

Unique Performance Considerations for Printable Organic Semiconductor and Perovskite Radiation Detectors: Toward Consensus on Best Practice Evaluation

Advanced Functional Materials, EarlyView.
A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

Advanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Observing electron localization in a dissociating H2+ molecule in real time

Nature Communications, 2017
Time resolved measurements provide insights to the intriguing process of ultrafast molecular fragmentation. Here the authors use CEP-locked laser pulses in pump–probe scheme to explore the H2+dissociation and find out that the electron localization to ...

Integrable crosscap states in gl $$ \mathfrak{gl} $$ (N) spin chains

Journal of High Energy Physics, 2022
We study the integrable crosscap states of the integrable quantum spin chains and we classify them for the gl $$ \mathfrak{gl} $$ (N) symmetric models. We also give a derivation for the exact overlaps between the integrable crosscap states and the Bethe ...
