Reservoir engineering for classical nonlinear fields

Physical Review Research
Reservoir engineering has become a prominent tool to control quantum systems. Recently, there have been first experiments applying it to many-body systems, especially with a view to engineer particle-conserving dissipation for quantum simulations using ...

Experimental quantum simulation of non-Hermitian dynamical topological states using stochastic Schrödinger equation

npj Quantum Information, 2022
Noise is ubiquitous in real quantum systems, leading to non-Hermitian quantum dynamics, and may affect the fundamental states of matter. Here we report in an experiment a quantum simulation of the two-dimensional non-Hermitian quantum anomalous Hall (QAH)

Dual‐Percolative Planar‐Heterojunction Photoactive System for High‐Performance Stretchable Organic Photovoltaics Enhancing Power Output under Strain

Advanced Functional Materials, EarlyView.
A dual‐percolative planar‐heterojunction photoactive architecture enables intrinsically stretchable organic photovoltaics that combine high photovoltaic efficiency with enhanced mechanical robustness. Abstract Intrinsically stretchable organic solar cells (IS‐OSCs) are promising candidates for wearable power sources due to their ability to deform in ...

Quantum bistability in the hyperfine ground state of atoms

Physical Review Research, 2023
First-order phase transitions are ubiquitous in nature; however, this notion is ambiguous and highly debated in the case of open quantum systems. We construct a paradigmatic example which allows for elucidating the key concepts.

Quantum metrology with boundary time crystals

Communications Physics, 2023
Quantum sensing is one of the arenas that exemplifies the superiority of quantum technologies over their classical counterparts. Such superiority, however, can be diminished due to unavoidable noise and decoherence of the probe.

Scalable Thermal Engineering via Femtosecond Laser‐Direct‐Written Phononic Nanostructures

Advanced Functional Materials, EarlyView.
This study demonstrates that femtosecond laser‐induced periodic surface structures (fs‐LIPSS) can function as phononic metasurfaces, reducing thermal conductivity below the plain thin‐film limit. Phonon Monte Carlo analysis reveals that the periodic structures restrict phonon mean free paths.

Stacking‐Engineered Magnonic Topology and Transport in Honeycomb Homobilayers

Advanced Functional Materials, EarlyView.
ABSTRACT Topological magnons have emerged as a promising platform for dissipationless bosonic transport. However, a straightforward and effective strategy to engineer such topological states in real materials has yet to be fully realized. Here, a general scheme for controlling magnonic topological states via stacking engineering in van der Waals ...
