Kauzmann Paradox, Supercooling, and Finding Order in Chaos

Angewandte Chemie, Volume 137, Issue 10, March 3, 2025.
80 years later: Kauzmann temperature (Tk), and associated entropy catastrophe/paradox remains an enigma for nearly 80 years without any unifying resolution. Potential resolutions to the Kauzmann paradox, however, have so far been limited in the existence of an equilibrium ideal glass transition and traditional description of phase transition. Continued

Calculation of the Density of States Using Discrete Variable Representation and Toeplitz Matrices

, 1995
A direct and exact method for calculating the density of states for systems with localized potentials is presented. The method is based on explicit inversion of the operator $E-H$.

Sound Attenuation in Quark Matter Due to Pairing Fluctuations

, 2016
The sound wave in dense quark matter is subject to strong absorption due to diquark field fluctuations above T critical. The result is another facet of Mandelshtam-Leontovich slow relaxation time theory.Comment: Talk at the 19th International Seminar ...

Toric amplitudes and universal adjoints

Journal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract A toric amplitude is a rational function associated with a simplicial polyhedral fan. The definition is inspired by scattering amplitudes in particle physics. We prove algebraic properties of such amplitudes and study the geometry of their zero loci. These hypersurfaces play the role of Warren's adjoint via a dual volume interpretation.

Physicochemical Characterization of Solid Catalysts: Morphological, Structural, Textural, Reducibility, and Acid‐Base Insights

ChemCatChem, Volume 17, Issue 23, December 8, 2025.
This review provides a practical guide for the characterization of solid catalysts, emphasizing key techniques such as SEM, TEM, XRD, Raman spectroscopy, and gas physisorption. It also covers reducibility and acid‐based analyses through TPR, TPD, and FTIR.

Pseudo-time Schroedinger equation with absorbing potential for quantum scattering calculations

, 2001
The Schroedinger equation with an energy-dependent complex absorbing potential, associated with a scattering system, can be reduced for a special choice of the energy-dependence to a harmonic inversion problem of a discrete pseudo-time correlation ...

Holomorphic field theories and higher algebra

Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Global Lunar Boulder Map From LRO NAC Optical Images Using Deep Learning: Implications for Regolith and Protolith

Journal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Boulders on the lunar surface indicate relatively recent surface activity, related to mass wasting or bedrock excavation by impact cratering, and degrade over time, producing regolith. Previously, the distribution of boulders was indirectly assessed using the anisothermality effects observed by the Lunar Reconnaissance Orbiter (LRO) Diviner ...
