非对称量子Rabi模型中的标度行为
Scaling behavior in the asymmetric quantum Rabi model
本文研究了非对称量子拉比模型中的标度行为和临界指数,该模型破坏了宇称对称性。该模型呈现出相变现象,并可用于推导临界指数。本文建立了一个包含两个标度变量的通用标度函数。此外,本文建立了临界指数之间的量子超标度关系。本文的研究表明,即使在临界耦合以下,仍然可以使用另一个标度变量来适用标度形式。本文希望这一发现能够为超辐射相变的实验研究提供有价值的见解,特别是在腔平台上,这个平台一直受制于众所周知的no-go定理的限制。
he scaling behavior and critical exponents are examined in the asymmetric quantum Rabi model, where the parity symmetry is violated. A phase transition occurs in this model, allowing for the determination of critical exponents. A general scaling function is formulated, encompassing two scaling variables. Additionally, a quantum hyper-scaling relation between critical exponents is established. The investigation reveals that the scaling form remains applicable, employing an alternative scaling variable, even when the coupling is below the critical point. This discovery offers valuable insights into the experimental investigation of the super-radiant phase transition, particularly in the cavity platform, which has been limited by the well-known no-go theorem.
