Entanglement spectrum as a marker for phase transitions in the density embedding theory for interacting spinless fermionic models
Xavier Plat, Chisa Hotta
Entanglement related properties work as nice fingerprint of the quantum many-body wave function. However, those of fermionic models are hard to evaluate in standard numerical metho…
Comparative study of the density matrix embedding theory for the Hubbard models
Masataka Kawano, Chisa Hotta
We examine the performance of the density matrix embedding theory (DMET) recently proposed in [G. Knizia and G. K.-L. Chan, Phys. Rev. Lett. 109, 186404 (2012)]. The core of this m…
Ferromagnetism out of charge fluctuation of strongly correlated electrons in -(BEDT-TTF)Hg(SCN)Br
Minoru Yamashita, Shiori Sugiura, Akira Ueda +10
We perform magnetic susceptibility and magnetic torque measurements on the organic -(BEDT-TTF)Hg(SCN)Br, which is recently suggested to host an exotic quantum dipole-liq…
Thermal Pure Quantum Matrix Product States Recovering a Volume Law Entanglement
Atsushi Iwaki, Akira Shimizu, Chisa Hotta
We propose a way to construct a thermal pure quantum matrix product state (TPQ-MPS) that can simulate finite temperature quantum many-body systems with a minimal numerical cost com…
Finite temperature thermodynamic properties of the spin-1 nematics in an applied magnetic field
Katsuhiro Tanaka, Chisa Hotta
We study numerically the thermodynamic properties of the spin nematic phases in a magnetic field in the spin-1 bilinear-biquadratic model. When the field is applied, the phase tran…
