AttoscienceJun 01 2008Fascinating developments in optical pulse engineering over the last 20 years lead to the generation of laser pulses as short as few femtosecond, providing a unique tool for high resolution time domain spectroscopy. However, a number of the processes in ... More
Low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chainJan 16 2014We derive the low-temperature large-distance asymptotics of the transversal two-point functions of the XXZ chain by summing up the asymptotically dominant terms of their expansion into form factors of the quantum transfer matrix. Our asymptotic formulae ... More
Functions Characterizing the Ground State of the XXZ Spin-1/2 Chain in the Thermodynamic LimitNov 27 2013Apr 11 2014We establish several properties of the solutions to the linear integral equations describing the infinite volume properties of the XXZ spin-1/2 chain in the disordered regime. In particular, we obtain lower and upper bounds for the dressed energy, dressed ... More
