Statistical Thermodynamics of Polymer Quantum Systems
Symmetry, Integrability and Geometry: Methods and Applications, 2011 Polymer quantum systems are mechanical models quantized similarly as loop quantum gravity. It is actually in quantizing gravity that the polymer term holds proper as the quantum geometry excitations yield a reminiscent of a polymer material.

From the conformal anomaly to the Virasoro algebra
Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.Abstract The conformal anomaly and the Virasoro algebra are fundamental aspects of two‐dimensional conformal field theory and conformally covariant models in planar random geometry. In this article, we explicitly derive the Virasoro algebra from an axiomatization of the conformal anomaly in terms of real determinant lines, one‐dimensional vector spaces

Spin foam model from canonical quantization [PDF]
, 2007 We suggest a modification of the Barrett-Crane spin foam model of four-dimensional Lorentzian general relativity motivated by the canonical quantization. The starting point is Lorentz covariant loop quantum gravity. Its kinematical Hilbert space is found

Physical states in canonically quantized supergravity [PDF]
Nuclear Physics B, 1994 We discuss the canonical quantization of $N=1$ supergravity in the functional Schrodinger representation. Although the form of the supersymmetry constraints suggests that there are solutions of definite order $n$ in the fermion fields, we show that there are no such states for any finite $n$.

Energy Landscapes in Chemical Reactions and Transport
ChemPhysChem, Volume 26, Issue 6, March 15, 2025.Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

Inverse Design of Planar Clamped‐Free Elastic Rods From Noisy Data
International Journal for Numerical Methods in Engineering, Volume 126, Issue 5, 15 March 2025.ABSTRACT Slender structures, such as rods, often exhibit large deformations even under moderate external forces (e.g., gravity). This characteristic results in a rich variety of morphological changes, making them appealing for engineering design and applications, such as soft robots, submarine cables, decorative knots, and more.

Exact Quantization of Nonreciprocal Quasilumped Electrical Networks
Physical Review XFollowing a consistent geometrical description previously introduced [Quantum 8, 1466 (2024)2521-327X10.22331/q-2024-09-09-1466], we present an exact method for obtaining canonically quantizable Hamiltonian descriptions of nonlinear, nonreciprocal ...

Canonical quantization of the electromagnetic field on the Kerr background [PDF]
, 2005 We investigate the canonical quantization of the electromagnetic field on the Kerr background. We give new expressions for the expectation value of the electromagnetic stress-energy tensor in various quantum states and give a physical interpretation of ...

Vertex Algebroids over Veronese Rings
Symmetry, Integrability and Geometry: Methods and Applications, 2008 We find a canonical quantization of Courant algebroids over Veronese rings. Part of our approach allows a semi-infinite cohomology interpretation, and the latter can be used to define sheaves of chiral differential operators on some homogeneous spaces ...
