This study validates universal Kibble-Zurek scaling laws within the Dicke model for experimentally realistic quantum systems, resolving long-standing issues regarding finite-size effects and energy dissipation. By unifying static and dynamic critical scaling analyses, the work provides a robust analytical framework for characterizing phase transitions in open quantum systems where photon loss is significant. These findings advance the theoretical understanding of light-matter interactions at mesoscopic scales, offering clearer pathways for interpreting rapid changes in complex quantum states.

Tsinghua University Confirms Kibble, Zurek Scaling in Light-Matter System

Quantum ZeitgeistSeptember 2, 20264 min read

Can complex light-matter interactions reliably predict system behaviour during rapid change? A new analytical framework confirms universal Kibble, Zurek scaling within the Dicke model, even when dealing with experimentally realistic sizes and energy loss. This resolves longstanding difficulties extracting accurate critical exponents from both static measurements *and* dynamic ‘ramping’ processes at mesoscopic scales.

Extracting precise critical exponents from quantum systems at experimentally accessible scales presents key challenges due to slow correlation times and photon loss influencing behaviour. A unified framework resolves static and dynamic critical scaling in both closed and open quantum systems using the Dicke model, enabling analysis previously obscured by finite size effects. An analytical method improves characterisation of phase transitions, points where materials change properties, at scales relevant to experiments. Standard…
