"Quenching the Lieb-Liniger model"

 

Abstract

 

Quantum quenches for the 1D Bose gas (Lieb-Liniger model) are discussed.

The first part of the talk discusses how the Algebraic Bethe Ansatz can be used for quantum quenches.  As an explicit example we quench the Lieb-Liniger model by instantaneously switching off the interactions.  The subsequent time evolution is studied for various correlation functions.  The long time average is compared with the predictions of several statistical ensembles.

The second part concerns the discussion of the generalized Gibbs ensemble for the Lieb-Liniger model by generalizing the well known TBA equations.

Possible applications and strategies are discussed.

"Full counting statistics of the interacting resonant level model"

 
 

Abstract

 

We discuss the full counting statistics of charge transport through a nano device and introduce a general way to calculate it numerically at zero-temperature.  We apply this to a strongly correlated model: the interacting resonant level model; where it turns out we can also calculate the full counting statistics exactly, to good agreement with the numerics.  From the analytic properties of the full solution, we show that the system undergoes charge fractionalization when the bias voltage exceeds a certain threshold.

"Artificial magnetic field for photons in a coupled cavity array"

 

Abstract

 

In this talk, I will present some of our recent theoretical results concerning photons in a coupled cavity array under a synthetic magnetic field.  A suitable coupling of the propagation and polarization degrees of freedom introduces a geometrical phase for photons tunneling between adjacent sites of a coupled cavity array, which gives rise to the artificial field.  I will discuss the feasibility of observing strong magnetic field effects in the optical spectra of realistic systems, including the Hofstadter butterfly spectrum.  I will also touch on the observability of a fractional quantum Hall effect for photons in these systems, which is expected to appear when effective interactions are induced between photons.
