Continuous harvesting of intermittent and continuous heats by a mixed ion/electron thermoelectric generator using an ionogel blended with carbon nanotube ionogels

This study presents a mixed ion/electron thermoelectric generator (MTEG) utilizing a carbon nanotube-blended ionogel that overcomes the intermittent limitations of traditional ionic devices to continuously harvest both steady and fluctuating heat into electricity with a thermopower significantly exceeding that of conventional electronic materials.

Density-Dependent Microwave Heating of Aluminum Nanoparticle Compacts: Experimental Thermography, HFSS Simulation, and Effective-Medium Modeling

This study demonstrates that increasing the relative density of cold-pressed aluminum nanoparticle compacts enhances microwave heating rates and steady-state temperatures due to improved energy conversion from reduced interparticle spacing, a trend validated by experimental thermography, HFSS simulations, and effective-medium modeling that collectively identify an optimal intermediate density for efficient microwave coupling.

Lightweight phase-field surrogate for modelling ductile-to-brittle transition through phenomenological elastoplastic coupling

This paper proposes a computationally efficient, lightweight phase-field surrogate model implemented in FEniCSx that captures the ductile-to-brittle transition in body-centred cubic systems by prescribing temperature dependence through phenomenological elastoplastic coupling, thereby enabling rapid parametric studies without the prohibitive cost of fully coupled thermomechanical simulations.

Hyperelastic characterization of a cylinder under tension -- torsion

This study presents a theoretical framework based on the Pucci–Saccomandi model to analyze the nonlinear mechanical response of an incompressible hyperelastic cylinder under combined tension and torsion, revealing pronounced strain-stiffening, strong axial-twist coupling, and the potential for Poynting effect reversal depending on material parameters.

Temporal-Mode interference type Quantum Photonic computation on curved-time photonic platforms

This paper proposes a quantum-photonic framework utilizing engineered acceleration-induced lapse fields on QCM/SAW substrates to treat time as a quantized harmonic coordinate, thereby enabling curved-time potentials that confine wavefunctions into discrete temporal eigenmodes and break conventional time-frequency trade-offs to facilitate ultrabroadband quantum computation and communication.

Occupation-selective topological pumping from Floquet gauge fields

This paper demonstrates that periodically driving a one-dimensional superlattice with density-dependent hopping creates occupation-selective topological pumping, where interaction-induced Floquet gauge fields enable two-body bound states (doublons) to exhibit quantized transport and distinct Chern numbers even when single-particle bands remain topologically trivial.

Hamiltonian dynamics from pure dissipation

This paper demonstrates that internal Hamiltonian dynamics can be effectively simulated using only external pure dissipation (Lindbladians without a coherent part) with optimal time scaling, establishing fundamental limits on the decoherence cost required to mimic reversible evolution and revealing significant implications for quantum complexity, simulation efficiency, and dynamical control.
