Variance-Driven Mean Temperature Reduction in Nonuniformly Heated Radiative-Conductive Systems

Juntao Lu, Zihan Zhang, Yongjian Xiong +1 more·Mar 4, 2026

Radiative-conductive systems are intrinsically nonlinear due to the quartic temperature dependence of thermal radiation. Under fixed total heating power, convexity arguments imply that nonuniform temperature distributions radiate more efficiently and...

Imaginary-time evolution of interacting spin systems in the truncated Wigner approximation

Tom Schlegel, Dennis Breu, Michael Fleischhauer·Mar 4, 2026

We present a semiclassical phase-space method to calculate thermal and ground states of large interacting spin systems. To this end, we extend the recently developed truncated Wigner approximation for spins (TWA) to the imaginary time, termed iTWA. T...

Kinematic budget of quantum correlations

Maaz Khan, Subhadip Mitra·Mar 4, 2026

The diversity of quantum correlations -- discord, entanglement, steering, and Bell nonlocality -- disappears at the observable second-moment kinematic level. By treating state purity as a finite resource, we introduce a local-unitary-invariant budget...
