Spontaneous symmetry breaking in open quantum systems: strong, weak, and strong-to-weak [PDF]

arXiv
Depending on the coupling to the environment, symmetries of open quantum systems manifest in two distinct forms, the strong and the weak. We study the spontaneous symmetry breaking among phases with different symmetries. Concrete Liouvillian models with strong and weak symmetry are constructed, and different scenarios of symmetry-breaking transitions ...

Implantable Self‐Powered Systems for Electrical Stimulation Medical Devices

Advanced Science, EarlyView.
In this paper, the design strategy and clinical application of ISS are discussed in depth from four aspects: the design and optimization of the energy collection module, the selection and preparation of adaptive electrode materials, the innovation of system design strategy, and the biological effect of electrical stimulation of ISS.

Subsurface Oxygen Vacancy Mediated Surface Reconstruction and Depolarization of Ferroelectric BaTiO3 (001) Surface

Advanced Science, EarlyView.
In‐situ atomic‐scale electron microscopy reveals that vacuum‐annealed ferroelectric BaTiO3 (001) surfaces exhibit BaO termination with periodic Ba deficiency and TiOx adunits. Planar oxygen vacancy accumulation in the subsurface TiO2 layer mitigates the depolarization field, facilitating cooperative rumpling of surface and subsurface layers in a tail ...

Formation of defects associated with both spontaneous and explicit symmetry breaking [PDF]

arXiv
We discuss formation of cosmic strings associated with a spontaneously broken approximate $U(1)$ symmetry by performing classical field-theoretical simulations. An original $U(1)$ symmetry is explicitly broken down to its subgroup $Z_N$ even before spontaneous breaking takes place.

Assessment and Mitigation of CRISPR‐Cas9‐Induced Nontargeted Translocations

Advanced Science, EarlyView.
Various inverted repeat elements are dispersed throughout genomes. This study reveals that these elements can cause significant chromosomal rearrangements when CRISPR editing occurs in their proximity. The risk can be mitigated by incorporating inverted repeat‐homologous segments into the CRISPR system, which represents a promising strategy for ...

Heteroatom‐Synergistic Effect on Anchoring Polysulfides In Chalcone‐Linked Nanographene Covalent Organic Frameworks for High‐Performance Li─S Batteries

Advanced Science, EarlyView.
A series of nanographene‐type covalent organic framework sulfur‐hosting cathodes are developed by introducing pyridine and chalcone functionalities to amend strong lithium polysulfides (LiPSs) interactions to suppress the shuttle effect in lithium‐sulfur (Li─S) batteries. The cathode material showed a specific capacity of 1228 mA h g−1 at 0.5C with 80%
