Universal entanglement signatures of interface conformal field theories
Qicheng Tang, Zixia Wei, Yin Tang +2
An interface connecting two distinct conformal field theories hosts rich critical behaviors. In this work, we investigate the entanglement properties of such critical interface the…
Charting the space of ground states with tensor networks
Marvin Qi, David T. Stephen, Xueda Wen +4
We employ matrix product states (MPS) and tensor networks to study topological properties of the space of ground states of gapped many-body systems. We focus on families of states…
Floquet's Refrigerator: Conformal Cooling in Driven Quantum Critical Systems
Xueda Wen, Ruihua Fan, Ashvin Vishwanath
We propose a general method of cooling -- periodic driving generated by spatially deformed Hamiltonians -- and study it in general one-dimensional quantum critical systems describe…
Flow of (higher) Berry curvature and bulk-boundary correspondence in parametrized quantum systems
Xueda Wen, Marvin Qi, Agnès Beaudry +5
This paper is concerned with the physics of parametrized gapped quantum many-body systems, which can be viewed as a generalization of conventional topological phases of matter. In…
Periodically, Quasi-periodically, and Randomly Driven Conformal Field Theories (II): Furstenberg's Theorem and Exceptions to Heating Phases
Xueda Wen, Yingfei Gu, Ashvin Vishwanath +1
In this sequel (to [Phys. Rev. Res. 3, 023044(2021)], arXiv:2006.10072), we study randomly driven dimensional conformal field theories (CFTs), a family of quantum many-body…
Floquet conformal field theories with generally deformed Hamiltonians
Ruihua Fan, Yingfei Gu, Ashvin Vishwanath +1
In this work, we study non-equilibrium dynamics in Floquet conformal field theories (CFTs) in 1+1D, in which the driving Hamiltonian involves the energy-momentum density spatially…
