Phase transitions in coupled Ising chains and SO()-symmetric spin chains
Yohei Fuji, Sylvain Capponi, Lukas Devos +1
The paper studies quantum phase transitions in a one‑dimensional system made of multiple coupled Ising chains, showing that for two or three chains the transition is continuous (Is…

Loop-current orderings in SU() two-leg fermionic ladder through duality symmetries
M. Habchy, F. Rose, P. Lecheminant
We investigate the formation of loop-current ordered phases in half-filled SU() two-leg fermionic ladders. Using a low-energy approach, we uncover the existence of non-perturbat…

Infrared properties of two-dimensional nonlinear models at nonzero angles
Philippe Lecheminant, Yuya Tanizaki, Keisuke Totsuka
A general strategy is proposed to explore the low-energy properties of two-dimensional nonlinear models with terms. We demonstrate its application to nonlinear model…
