Quasi-autonomous quantum thermal machines and quantum to classical energy flow

New Journal of Physics, 2016
There are both practical and foundational motivations to consider the thermodynamics of quantum systems at small scales. Here we address the issue of autonomous quantum thermal machines that are tailored to achieve some specific thermodynamic primitive ...

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 ...

Removing Homocoupling Defects in Alkoxy/Alkyl‐PBTTT Enhances Polymer:Fullerene Co‐Crystal Formation and Stability

Advanced Functional Materials, EarlyView.
PBTTT‐OR‐R, a C14‐alkoxy/alkyl‐PBTTT polymer derivative, is of substantial interest for optoelectronics due to its specific fullerene intercalation behavior and enhanced charge‐transfer absorption. Comparing this polymer with (S) and without (O) homocoupling defects reveals that PBTTT‐OR‐R(O) forms stable co‐crystals with PC61BM, while PBTTT‐OR‐R(S ...

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.

Intrinsic Decoherence Dynamics in Smooth Hamiltonian Systems: Quantum-classical Correspondence

, 2003
A direct classical analog of the quantum dynamics of intrinsic decoherence in Hamiltonian systems, characterized by the time dependence of the linear entropy of the reduced density operator, is introduced.

Deciphering the Origin of Higher Shell Coordination on Single Iron Catalysts for Resilient Modulating Persulfate Oxidation Into Singlet Oxygen Pathway

Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reveals that higher shell S coordination can effectively modulate the spin state of FeN4 site via long‐range electronic interactions, giving rise to the oriented generation of singlet oxygen from peroxymonosulfate activation. Abstract Precise manipulation of coordination structure of single‐atom sites and establishment of schematic ...

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 ...
