The Thermodynamics of the Gravity from Entropy Theory

Ginestra Bianconi·Oct 26, 2025

The Gravity from Entropy (GfE) action posits that the fundamental nature of gravity is information encoded in the metric degrees of freedom. This statistical mechanics theory is associated with the GfE Lagrangian given by the Geometric Quantum Relati...

Nonlinear optical behavior of confined electrons under torsion and magnetic fields

Carlos Magno O. Pereira, Edilberto O. Silva·Oct 25, 2025

In this work, we investigate the influence of torsion, Aharonov-Bohm flux, and external magnetic fields on the linear and nonlinear optical properties of a confined quantum system. The confinement potential is not assumed a priori, but emerges as a r...

The spinterface mechanism for the chiral-induced spin selectivity effect: A Critical Perspective

Subhajit Sarkar, Amos Sharoni, Oliver L. A. Monti +1 more·Oct 24, 2025

The chiral-induced spin selectivity (CISS) effect, whereby chiral molecules preferentially transmit electrons of one spin orientation, remains one of the most intriguing and debated phenomena at the interface of spintronics, molecular electronics, an...

Absence of gravitationally induced entanglement in certain semi-classical theories of gravity

Ward Struyve·Oct 23, 2025

Bose et al. and Marletto and Vedral proposed an experiment to test whether gravity can induce entanglement between massive systems, arguing that the capacity to do so would imply the quantum nature of gravity. In this work, a class of semi-classical ...

Landau Polarons as Generators of Quantum-Coherent States

Arnab Ghosh, Patrick Brosseau, Dmitry N. Dirin +3 more·Oct 23, 2025

Since Landau's theory, polarons have been understood as quasiparticles in which charges are dressed by the lattice field, yet decades of transport and spectroscopic studies have yielded only static indirect renormalizations. Whether such dressing can...

Restoring Quantum Superiority of Noisy Quantum Illumination

Wei Wu, Jun-Hong An·Oct 23, 2025

Quantum illumination uses quantum entanglement as a resource to enable higher-resolution detection of low-reflectivity targets than is possible with classical techniques. This revolutionary technology could transform modern radar. However, it is wide...

Kondo breakdown induced by the non-Hermitian complex hybridization

Kazuki Yamamoto, Masaya Nakagawa, Norio Kawakami·Oct 23, 2025

Recently, a non-Hermitian Anderson impurity model with one-body loss has been studied in [Phys. Rev. B 111, 125157 (2025)}], and it has been demonstrated that the renormalization effect generated by strong correlations counterintuitively changes the ...

Absence of measurement- and unraveling-induced entanglement transitions in continuously monitored one-dimensional free fermions

Clemens Niederegger, Tatiana Vovk, Elias Starchl +1 more·Oct 22, 2025

Continuous monitoring of one-dimensional free fermionic systems can generate phenomena reminiscent of quantum criticality, such as logarithmic entanglement growth, algebraic correlations, and emergent conformal invariance, but in a nonequilibrium set...
