Time-dependent integrable quantum field theories with dynamical boundaries

We present a method for constructing time-dependent integrable chiral quantum field theories on a finite spatial interval from the scattering and reflection data of an autonomous integrable model. Each particle carries a spectral label that is constant along its free trajectory. Requiring a right--left scattering event...

General Construction of Time-Dependent Integrable Chiral Field Theories

We develop a general procedure for constructing time-dependent integrable chiral field theories from autonomous unitary difference-form $S$-matrices satisfying the Yang-Baxter equation. Spectral parameters are transported along the free right- and left-moving characteristics, defining a map from physical spacetime to s...

Integrable Chiral Quantum Field Theories with Spacetime-Dependent Interactions

We construct a class of integrable chiral fermionic quantum field theories with interactions depending on both space and time. The construction starts with a unitary, regular, difference-form two-body scattering matrix that satisfies braiding unitarity and the Yang--Baxter equation. Each freely moving right- or left-mo...
