Finite temperature correlation functions of the sine--Gordon model
M. Tóth, J. H. Pixley, G. Takács +1
The sine-Gordon model serves as a foundational -dimensional quantum field theory with numerous applications in condensed matter physics. Despite its integrability, characteriz…
Observing quantum phase transitions at non-zero temperature: non-analytic behavior of order-parameter correlation times
István Csépányi, Giuseppe Del Vecchio Del Vecchio, Benjamin Doyon +1
Phase transitions occur when a macroscopic number of local degrees of freedom coherently change their behavior. In ground states of quantum many-body systems, phase transitions due…
Full counting statistics in the sine-Gordon model
Botond C. Nagy, Marton Kormos, Márton Kormos +2
Full counting statistics (FCS) is a dynamical generalisation of the free energy, encapsulating detailed information about the distribution and large-scale correlation functions of…
Anomalous charge transport in the sine-Gordon model
Frederik Møller, Botond C. Nagy, Márton Kormos +1
We conduct a comprehensive study of anomalous charge transport in the quantum sine--Gordon model. Employing the framework of Generalized Hydrodynamics, we compute Drude weights and…
