Harvest Ambient Heat via Constraint-Shaped Phase-Change Cycles: Micro , Subcooled Liquid, and Liquid-Only Compression
Ting Peng
Conventional heat engines typically require two distinct thermal reservoirs, with their efficiency strictly bounded by the Carnot limit. We present a theoretical design for a phase…

Entropy Has No Direction: A Mirror-State Paradox Against Universal Monotonic Entropy Increase and a First-Principles Proof that Constraints Reshape the Entropy Distribution
Ting Peng
We revisit textbook claims that entropy must increase and show that, under time-reversal invariant microscopic dynamics, no universal trajectory-wise or statistical assertion that…

Geometry Challenges Entropy: Regime-DependentRectification in Nanofluidic Cascades
Ting Peng
Can geometry alone reshape equilibrium? Cascaded nanofluidic chambers show complex accumulation patterns, traditionally attributed to geometric diode effects. We use 3D molecular d…
