Schwinger-Dyson approximants

Bartomeu Fiol, Elena Gijon, Unai Lejarza Alonso

We revisit the solution to the Schwinger-Dyson equations in the simple case of the 0-dimensional $\frac{1}{2} m^{2} I ¨ ^{2} + \frac{I ^}{»} 4 I ¨ ^{4}$ theory with $m^{2} > 0$ and $I^» \geq 0$ . We argue…

Conformal line defects at finite temperature

Julien Barrat, Bartomeu Fiol, Enrico Marchetto +2

We study conformal field theories at finite temperature in the presence of a temporal conformal line defect, wrapping the thermal circle, akin to a Polyakov loop in gauge theories.…
