Generalized Real-space Chern Number Formula and Entanglement Hamiltonian
Ruihua Fan, Pengfei Zhang, Yingfei Gu
We generalize a real-space Chern number formula for gapped free fermions to higher orders. Using the generalized formula, we prove recent proposals for extracting thermal and elect…
Linear in temperature resistivity in the limit of zero temperature from the time reparameterization soft mode
Haoyu Guo, Yingfei Gu, Subir Sachdev
The most puzzling aspect of the 'strange metal' behavior of correlated electron compounds is that the linear in temperature resistivity often extends down to low temperatures, lowe…
Emergent Spatial Structure and Entanglement Localization in Floquet Conformal Field Theory
Ruihua Fan, Yingfei Gu, Ashvin Vishwanath +1
We study the energy and entanglement dynamics of D conformal field theories (CFTs) under a Floquet drive with the sine-square deformed (SSD) Hamiltonian. Previous work has s…
Transport and chaos in lattice Sachdev-Ye-Kitaev models
Haoyu Guo, Yingfei Gu, Subir Sachdev
We compute the transport and chaos properties of lattices of quantum Sachdev-Ye-Kitaev islands coupled by single fermion hopping, and with the islands coupled to a large number of…
Fast scrambling on sparse graphs
Gregory Bentsen, Yingfei Gu, Andrew Lucas
Given a quantum many-body system with few-body interactions, how rapidly can quantum information be hidden during time evolution? The fast scrambling conjecture is that the time to…
fractionalized phases of a solvable, disordered, - model
Wenbo Fu, Yingfei Gu, Subir Sachdev +1
We describe the phases of a solvable - model of electrons with infinite-range, and random, hopping and exchange interactions, similar to those in the Sachdev-Ye-Kitaev models…
Thermoelectric transport in disordered metals without quasiparticles: the SYK models and holography
Richard A. Davison, Wenbo Fu, Antoine Georges +3
We compute the thermodynamic properties of the Sachdev-Ye-Kitaev (SYK) models of fermions with a conserved fermion number, . We extend a previously proposed Schwarzian…
