Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Controls on Iron‐Redox State in Martian Magmas Quantified by Mössbauer Spectroscopy, Colorimetric Wet Chemistry, and XANES Spectroscopy

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract To elucidate the relationship between oxygen fugacities (fO2) recorded in martian basalts and redox processes in the martian interior, superliquidus 100‐kPa furnace experiments on a composition similar to Humphrey (Adirondack basalt) were conducted at variable fO2 and temperature. Quenched glasses were analyzed by EPMA, Mössbauer spectroscopy,

Phantasmic Encounters in the Arctic: Haunting Materialities Beyond the Ghosts of War

open access: yesAnthropology of Consciousness, Volume 37, Issue 1, Spring 2026.
ABSTRACT In the vast north, ghostly experiences are common for locals and outsiders alike. Here, we explore how cultural‐natural attributes, like remoteness and extreme seasonal variation, compound experiences of the haunting in visceral ways. This provides the Arctic region with an unusually pronounced baseline of other‐than‐human agency, which in the

Emergent Horizons in the Laboratory

open access: yes, 2010
The concept of a horizon known from general relativity describes the loss of causal connection and can be applied to non-gravitational scenarios such as out-of-equilibrium condensed-matter systems in the laboratory.

Breathing Life Flows Through Chaos: Reconfiguring the Effectiveness of Five‐Finger Breathing in Mental Health First Aid

open access: yesAnthropology of Consciousness, Volume 37, Issue 1, Spring 2026.
ABSTRACT This article questions the moral and causal certainties attributed to the clinical assumptions of the breath of chaos. Instead of seeing chaos as an exceptional intruder that causes problems in health, I suggest that chaos underlines the changing conditions of health and it's an intrinsic part of breathing and everyday life. I discuss the five‐

Averaged null energy condition in Loop Quantum Cosmology

open access: yes, 2008
Wormhole and time machine are very interesting objects in general relativity. However, they need exotic matters which are impossible in classical level to support them.

Granice fizyki w kosmologii

open access: yesZagadnienia Filozoficzne w Nauce, 2015
The message is that physics has an „outward bound” of scientific inquiry in the field of cosmology. I present it in the historical development. Physics and astronomy, developing since the seventeenth century, inherited from the early Greek philosophers ...

Consistent discrete gravity solution of the problem of time: a model

open access: yes, 2003
The recently introduced consistent discrete lattice formulation of canonical general relativity produces a discrete theory that is constraint-free. This immediately allows to overcome several of the traditional obstacles posed by the ``problem of time ...

The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, Volume 74, Issue 2, February 2026.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

Universal Constants, Standard Models and Fundamental Metrology

open access: yes, 2009
Taking into account four universal constants, namely the Planck's constant $h$, the velocity of light $c$, the constant of gravitation $G$ and the Boltzmann's constant $k$ leads to structuring theoretical physics in terms of three theories each taking ...
