Tripartite entanglement in chaotic eigenstates
Junjia Zhang, Ramanjit Sohal, Shinsei Ryu
It is now well-established that classical statistical mechanics emerges from the entanglement structure of quantum chaotic systems, as quantified by the (subsystem) eigenstate ther…
Twisted-Boundary-Condition Formalism for Thermal Transport and an Application to the One-Dimensional XY Spin Chain
Ryota Nakai, Taozhi Guo, Shinsei Ryu
We introduce and formulate the boundary condition twisted by the energy (time translation) in one-dimensional quantum many-body systems. The stiffness against this boundary conditi…
Lieb-Schultz-Mattis Theorem in Open Quantum Systems
Kohei Kawabata, Ramanjit Sohal, Shinsei Ryu
The Lieb-Schultz-Mattis (LSM) theorem provides a general constraint on quantum many-body systems and plays a significant role in the Haldane gap phenomena and topological phases of…
Spatial deformation of many-body quantum chaotic systems and quantum information scrambling
Kanato Goto, Taozhi Guo, Tomoki Nosaka +3
We study the effect of spatial inhomogeneity on quantum information scrambling, a process of spreading and locally hiding quantum information in quantum many-body systems. As a par…
Higher structures in matrix product states
Shuhei Ohyama, Shinsei Ryu
For a parameterized family of invertible states (short-range-entangled states) in dimensions, we discuss a generalization of the Berry phase. Using translationally-invarian…
Extracting higher central charge from a single wave function
Ryohei Kobayashi, Taige Wang, Tomohiro Soejima +2
A (2+1)D topologically ordered phase may or may not have a gappable edge, even if its chiral central charge is vanishing. Recently, it is discovered that a quantity regarded…
