27.11.2025 by pricpr

$A disruption in the spacetime manifold, $ \mathcal{M}\_{xt}$, manifests as an infinite value within the momentum-energy manifold, $ \mathcal{M}\_{kE}$, suggesting a fundamental correspondence between these geometric representations of physical reality.$

A new theoretical framework proposes a unified description of quantum mechanics by extending wavefunction evolution to both spacetime and momentum-energy domains.

Beyond the Usual: Thermodynamics in ‘Fuzzy’ Space

27.11.2025 by pricpr

$The partition function $Z_q(\beta)$ for an electron within a noncommutative plane exhibits variation as influenced by both the non-extensivity parameter $q$ and inverse temperature $\beta$, demonstrating a relationship between these variables in defining the system’s quantum state.$

The study demonstrates that a quantum system’s coherent superposition-manifesting as spatially separated lobes and interference-can selectively activate a latent gauge field, distorting it in a manner unattainable through classical mixtures with identical coarse-grained mass profiles, thereby revealing a coherence-selective coupling mechanism.

A new theoretical framework proposes that coherence, not just charge, can experience gauge interactions, potentially unlocking the secrets of decoherence and entanglement.

$Er$^{3+}$ energy level fluctuations within a GaX-TiO$_{2}$ heterostructure arise from the interplay of interfacial Er$^{3+}$ ions, diffusing Ga spins, oxygen vacancies, and resulting strain, manifesting as a distance-dependent inhomogeneous lineshape and spectral noise density-characterized by a $d^{-3}$ decay with a characteristic length of 4 nm-that reveals the complex magnetic landscape at the interface.$

New research reveals how controlling strain, defects, and interfacial chemistry can unlock long-lived quantum coherence in rare-earth ions embedded within complex heterostructures.

27.11.2025 by pricpr

$The interplay between dissipation and squeezing reveals a phase transition in a two-oscillator system, where increasing dissipation-represented by the parameter $ \gamma $-sharpens the boundaries between $PT$-symmetric and broken-$PT$-symmetric phases, ultimately dictating whether normal modes exhibit sustained oscillatory behavior or decay into overdamped, non-oscillatory dynamics within the $(M_1, M_2)$ plane.$

New research reveals how coupling quantum systems to squeezed light reservoirs enables directional energy flow and opens doors to advanced thermodynamic devices.
