Do any causeless phenomenon exist in Quantum realm which could not be explained by intrinsic property and even be attributed to else factors? Even if not accepted in mainstream academia are there any present hypothesis about causeless phenomenon in Quantum realm.

We’ve got another notable first in the field of physics to report: A specific type of quantum behavior in waves of heat has now been observed at room temperature, rather than at the ultra-low cryogenic temperatures that are usually required. The quantum behavior is phonon focusing, which is where atomic-level, heat-carrying vibrations (the quantum packets […]

Nature Communications, Published online: 05 September 2026; doi:10.1038/s41467-026-77413-3 The authors introduce a practical game that distinguishes quantum from classical behaviour without relying on unproven assumptions. Quantum computers achieve exponentially larger scores than any classical strategy, a result confirmed in experiments.

_Erkenntnis_. forthcomingWhat becomes of the kinematics-dynamics distinction if spacetime is not fundamental, as several approaches to quantum gravity suggest? Two conceptions of this distinction, the temporal evolution and the constraint-based account, coexist within well-confirmed physics. We argue that, where spacetime emergence challenges a fundamental separation between states and principles…

Brilliant paper https://arxiv.org/abs/2202.04203v2 recently published in Nature Communications (open access) https://www.nature.com/articles/s41467-024-47170-2 resolves and demystifies the Frauchiger-Renner paradox associated with the Wigner friend problem. The resolution of the... Read more

Scientists have uncovered an unusual form of electron behavior in zirconium pentatelluride, a quantum material that can act as both an insulator and a conductor. Under temperatures near absolute zero and magnetic fields reaching 60 tesla, electrons produced quantum oscillations that continued even after conventional physics predicted they should disappear.

Directly visualising the inherent uncertainty within empty space has long remained an elusive goal. Now, images from a Bose, Einstein condensate reveal spatial patterns arising from quantum vacuum fluctuations, a feat previously limited to observing their indirect effects via electromagnetic sampling. This system uniquely emulates a massive relativistic sine-Gordon field, enabling laboratory stud…

Coherent states in complex systems have traditionally demanded extensive computation or relied upon approximations that struggle with irregular boundaries. Now, a new mathematical technique offers an alternative by constructing these states without explicitly calculating eigenstates for certain geometries. This allows analytical solutions, utilising established functions like those of Jacobi and …

An ultra-clean crystal surface allowed individual molecules to preserve quantum coherence at the fundamental Fourier limit. A molecule placed on a surface should be easier to probe and manipulate than one hidden inside a solid or suspended in vacuum. In practice, however, surface contamination creates an unstable, noisy environment that can quickly degrade the molecule’s [...]

sensor in slit must interact with photon, so isn't sensor reason why patterns on screen change? So what is exactly weird in this experiment? Can we somehow observe photon in slit but do not physically interact with him?

Transitionless quantum driving is a concept that was invented by Berry in 2009. In his article on transitionless quantum driving he showed that it is possible to speed up adiabatic evolution of eigenstates without generating transitions between eigenstates. By introducing an auxiliary Hamiltonian known as a counter-diabatic Hamiltonian , it is possible to drive eigenstates of an arbitrary Hamilt…
