Cluster Formation and Phase Transitions Induced by Vibrational Strong Coupling

Angewandte Chemie, Volume 138, Issue 1, 2 January 2026.
Non ‐ resonant Rayleigh scattering reveals that vibrational strong coupling induces clustering and phase transitions in liquids that undergo well defined transitions with temperature and solvent composition. Abstract Vibrational strong coupling (VSC) has been shown to significantly modify the chemical and physical properties of molecules and materials.

Homomorphic Encryption on GPU

IEEE Access, 2023
Homomorphic encryption (HE) is a cryptosystem that allows the secure processing of encrypted data. One of the most popular HE schemes is the Brakerski-Fan-Vercauteren (BFV), which supports somewhat (SWHE) and fully homomorphic encryption (FHE).

A Pipelined Hardware Design of FNTT and INTT of CRYSTALS-Kyber PQC Algorithm

Information
Lattice-based post-quantum cryptography (PQC) algorithms demand number theoretic transform (NTT)-based polynomial multiplications. NTT-based polynomials’ multiplication relies on the computation of forward number theoretic transform (FNTT) and inverse ...

Ultrabroadband Spacetime Nanoscopy of Terahertz Polaritons in a van der Waals Cavity

Small, EarlyView.
This work introduces SYnchrotron SpaceTimE Mapping (SYSTEM), which captures real‐time evolution of polariton wave packets with ∼10 nm spatial and sub‐100 fs temporal resolution across an ultrabroadband 5 to 50 THz range. Here, SYSTEM directly visualizes the creation, interference, and decay of multiple high‐quality Fabry‐Pérot phonon polariton cavity ...
