Minimal coupling in oscillator models of quantum dissipation
, 2012 The dissipative harmonic oscillator has two representations. In the first representation the central oscillator couples with its position to an oscillator bath. In the second one it couples with its momentum to the bath.

A quantum violation of the second law? [PDF]
, 2006 An apparent violation of the second law of thermodynamics occurs when an atom coupled to a zero-temperature bath, being necessarily in an excited state, is used to extract work from the bath.

Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Symmetry Enhanced Unconventional Spin Current Anisotropy in a Collinear Antiferromagnet
Advanced Functional Materials, EarlyView.Spin‐orbit torques (SOTs) are investigated in epitaxial FeSn, a topological antiferromagnet with kagome lattice symmetry. Combining experimental and theoretical approaches, the study identifies a six‐fold conventional damping‐like spin‐orbit torque (DL SOT), along with the coexistence of both six‐fold and uniaxial unconventional field‐like torque (FL ...

Rapid Diagnostics of Reconfigurable Intelligent Surfaces Using Space‐Time‐Coding Modulation
Advanced Functional Materials, EarlyView.A fast reconfigurable‐intelligent‐surface (RIS) diagnostics method is proposed based on spatio‐temporal modulation with orthogonal codes. Theoretical analysis demonstrates a clear distinction in code channel power between normal and faulty elements. Simulations validate its feasibility under high fault ratios and varying receiving angles.
