Regularization of a strong-weak duality between pointlike interactions in one dimension
Etienne Granet
Pointlike interactions between bosons in 1D are related to pointlike interactions between fermions through the Girardeau mapping. This mapping is a strong-weak duality since the co…
Duality between weak and strong interactions in quantum gases
Etienne Granet, Bruno Bertini, Fabian H. L. Essler
In one dimensional quantum gases there is a well known "duality" between hard core bosons and non-interacting fermions. However, at the field theory level, no exact duality connect…
Out-of-equilibrium dynamics of the XY spin chain from form factor expansion
Etienne Granet, Henrik Dreyer, Fabian H. L. Essler
We consider the XY spin chain with arbitrary time-dependent magnetic field and anisotropy. We argue that a certain subclass of Gaussian states, called Coherent Ensemble (CE) follow…
Quantum computing critical exponents
Henrik Dreyer, Mircea Bejan, Etienne Granet
We show that the Variational Quantum-Classical Simulation algorithm admits a finite circuit depth scaling collapse when targeting the critical point of the transverse field Ising c…
Systematic strong coupling expansion for out-of-equilibrium dynamics in the Lieb-Liniger model
Etienne Granet, Fabian H. L. Essler
We consider the time evolution of local observables after an interaction quench in the repulsive Lieb-Liniger model. The system is initialized in the ground state for vanishing int…
