Spectral functions in one-dimensional quantum systems at T>0
Thomas Barthel, Ulrich Schollwöck, Steven R. White
We present for the first time time-dependent density-matrix renormalization-group simulations (t-DMRG) at finite temperatures. It is demonstrated how a combination of finite-temper…

Entanglement and boundary critical phenomena
Huan-Qiang Zhou, Thomas Barthel, John Ove Fjaerestad +1
We investigate boundary critical phenomena from a quantum information perspective. Bipartite entanglement in the ground state of one-dimensional quantum systems is quantified using…
