Symmetric configurations highlighted by collective quantum coherence
Recent developments in quantum gravity have shown the Lorentzian treatment to be a fruitful approach towards the emergence of macroscopic space-times. In this paper, we discuss another related aspect of the Lorentzian treatment: we argue that collective ...

Endogenous/exogenous stimuli‐responsive smart hydrogels for diabetic wound healing
This figure illustrates smart hydrogels, persuaded to respond to various stimuli such as temperature, pH, and glucose levels. These smart hydrogels find extensive applications in drug delivery, tissue engineering, and diabetic wound healing due to adapting dynamically to environmental changes.

Quantum Big-Bounce as a phenomenology of RQM in the Mini-superspace
We investigate the emergence of a quantum Big-Bounce in the context of an isotropic Universe, filled by a self-interacting scalar field, which plays the role of a physical clock. The bouncing cosmology is the result of a scattering process, driven by the

Symplectic Structure of Intrinsic Time Gravity
The Poisson structure of intrinsic time gravity is analysed. With the starting point comprising a unimodular three-metric with traceless momentum, a trace-induced anomaly results upon quantization.

Relational Lorentzian Asymptotically Safe Quantum Gravity: Showcase Model
In a recent contribution, we identified possible points of contact between the asymptotically safe and canonical approaches to quantum gravity. The idea is to start from the reduced phase space (often called relational) formulation of canonical quantum ...

Micro-canonical and canonical description for generalised entropy
Few parameters dependent generalised entropy includes Tsallis entropy, Rényi entropy, Sharma-Mittal entropy, Barrow entropy, Kaniadakis entropy, etc as particular representatives. Its relation to physical systems is not always clear.

Tunnelling to holographic traversable wormholes
We study nonperturbative effects of quantum gravity in a system consisting of a coupled pair of holographic CFTs. The AdS$_4$/CFT$_3$ system has three possible ground states: two copies of empty AdS, a pair of extremal AdS black holes, and an eternal AdS
