Fermi-Dirac Wigner function for massive spin-1/2 particles in local equilibrium

Sudip Kumar Kar, Valeriya Mykhaylova·Nov 12, 2025

A recently proposed Boltzmann local equilibrium Wigner function for massive spin-1/2 particles is generalized to the case of Fermi-Dirac statistics. The resulting formula ensures the correct normalization of the mean polarization vector and reproduce...

Degeneracy beyond the parity-symmetry protection in one-dimensional spinless models: The parity-violating Kerr parametric oscillator

Jamil Khalouf-Rivera, Miguel Carvajal, Francisco Pérez-Bernal·Nov 12, 2025

One-dimensional quantum systems that undergo spontaneous symmetry-breaking, having a symmetric (non-degenerate) and a broken-symmetry (doubly-degenerate) phase, have been intensely studied in different branches of physics. In most cases, the spontane...

Private Remote Phase Estimation over a Lossy Quantum Channel

Farzad Kianvash, Marco Barbieri, Matteo Rosati·Nov 12, 2025

Private remote quantum sensing (PRQS) aims at estimating a parameter at a distant location by transmitting quantum states on an insecure quantum channel, limiting information leakage and disruption of the estimation itself from an adversary. Previous...

Operational Coherent Measurements with Steering and Randomness

Chellasamy Jebarathinam, Huan-Yu Ku, Hsi-Sheng Goan·Nov 12, 2025

Measurement incompatibility underpins randomness generation in nonlocal phenomena. However, at its root, a more fundamental quantum feature is noncommuting (or coherent) measurements. This raises a central question: How can we operationally character...
