Coherent intertwiner solution of simplicity constraint in all dimensional loop quantum gravity [PDF]
Physical Review D, 2019 We propose a new treatment of the quantum simplicity constraints appearing in the general ${SO(D+1)}$ formulation of loop quantum gravity for the ${(1+D)}$-dimensional space-time. Instead of strongly imposing the constraints, we construct a specific form

Bouncing evolution in a model of loop quantum gravity [PDF]
Physical Review D, 2019 To understand the dynamics of loop quantum gravity, the deparametrized model of gravity coupled to a scalar field is studied in a simple case, where the graph underlying the spin network basis is one loop based at a single vertex.

Advanced Photonics Research, EarlyView.A scalable, low‐cost approach for assembling single germanium nanowires (NWs) into photodetectors is demonstrated using a modified dielectrophoresis method with a voltage‐divider circuit. This self‐limiting assembly technique achieves ultrahigh responsivity (>6 × 105 A W−1) at 700 and 1550 nm without requiring nanoscale electrodes, offering a versatile

Burn‐Safe Biodegradable Magnetocaloric Composites for Temperature‐Controlled Biomedical Applications
Advanced Science, EarlyView.This work investigates a magnetocaloric (Mn,Fe)2(P,Si) compound tailored for precise, self‐regulating heating in biomedical use. With a Curie temperature tuned at 43 °C, it enables therapeutic activation without overheating. Encapsulation in a composite ensures controlled temperature rise under an alternating magnetic field (AMF), with high ...

Improved μ¯ -scheme effective dynamics of full loop quantum gravity [PDF]
, 2019 We propose a new derivation from the full Loop Quantum Gravity (LQG) to the Loop Quantum Cosmology (LQC) improved $\bar{\mu}$-scheme effective dynamics, based on the reduced phase space formulation of LQG and a proposal of effective Hamiltonian/action in

Gauge-invariant bounce from loop quantum gravity [PDF]
Classical and quantum gravity, 2019 We present a gauge-invariant treatment of singularity resolution using loop quantum gravity techniques with respect to local SU(2) transformations. Our analysis reveals many novel features of quantum geometry which were till now hidden in models based on
