# Matrix product state approach for a quantum system at finite temperatures using random phases and Trotter gates

8 Mar 2021ShimpeiGoto/RPMPS-T

We develop a numerical method based on matrix product states for simulating quantum many-body systems at finite temperatures without importance sampling and evaluate its performance in spin 1/2 systems.

# Window Function for Chirped Pulse Spectroscopy with Enhanced Signal-to-noise Ratio and Lineshape Correction

2 Mar 2021phlam-spectro-THz/voigt-1d

The application of window function as a tool for lineshape correction and signal-to-noise ratio (SnR) enhancement is rarely discussed in chirped spectroscopy, with the only exception of using Kaiser-Bessel window and trivial rectangular window.
