Symmetry‐Imposed Selection Rules for Excitations of Nontrivial Plasmonic Topologies
Advanced Science, EarlyView.A unified group‐theory selection rule governs the excitation of vectorial nearfield topologies across three plasmonic spin states. Derived from first principles, it predicts spin–orbit vortex splitting and multidimensional nested vortices, confirmed by phase‐resolved in situ measurements.

Stochastic thermodynamics and hierarchy of fluctuation theorems with multiple reservoirs
New Journal of Physics, 2018 We reformulate stochastic thermodynamics in terms of noise realizations for Langevin systems in contact with multiple reservoirs and investigate the structure of the second laws of thermodynamics.

Nonequilibrium thermodynamics of erasure with superconducting flux logic
Physical Review Research, 2020 We implement a thermal-fluctuation-driven logical bit reset on a superconducting flux logic cell. We show that the logical state of the system can be continuously monitored with only a small perturbation to the thermally activated dynamics at 500 mK.

Fluctuation theorems for excess and housekeeping heat for underdamped Langevin systems
, 2014 We present a simple derivation of the integral fluctuation theorems for excess and housekeeping heat for an underdamped Langevin system, without using the concept of dual dynamics.

Advanced Science, EarlyView.As CMOS technology approaches fundamental energy limits, new paradigms for low‐power information processing are required. Magnetic systems are attractive for their spin transport, yet current‐induced magnetization control is energy inefficient. Multiferroic heterostructures enable energy‐efficient electric field manipulation of magnetism.

Advanced Science, EarlyView.A nuclear‐pore‐inspired nested dual‐loop architecture redistributes electromagnetic energy through coupled transport, confinement, and dissipation pathways. Integrated with Co/Fe3O4 dual‐magnetic composites and topology optimization, the 11‐mm‐thick absorber delivers continuous 2–40 GHz attenuation, raises finite‐band structural utilization to 82%, and

Fluctuation theorems in general relativistic stochastic thermodynamics [PDF]
Based on the recently proposed framework of general relativistic stochastic mechanics and stochastic thermodynamics at the ensemble level, this work focuses on general relativistic stochastic thermodynamics at the trajectory level.

Fluctuation theorem as a special case of Girsanov theorem
Journal of Physics A: Mathematical and TheoreticalAbstract Stochastic thermodynamics is an important development in the direction of finding general thermodynamic principles for non-equilibrium systems. We believe stochastic thermodynamics has the potential to benefit from the measure-theoretic framework of stochastic differential equations (SDEs).

Fluctuation Theorem for Heat Flow
International Journal of Thermophysics, 2001 Thermal conduction in a classical many-body system which is in contact with two isothermal reservoirs maintained at different temperatures is considered. The probability that when observed for a finite time, the heat flux of a finite system flows in the reverse direction to that required by the Second Law of Thermodynamics is calculated from first ...

Advanced Science, EarlyView.Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.
