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…
Majorana fermions and the Sensitivity Conjecture
Yingfei Gu, Xiao-Liang Qi
Recently, Hao Huang proved the Sensitivity Conjecture, an important result about complexity measures of Boolean functions. We will discuss how this simple and elegant proof turns o…
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…
On the relation between the magnitude and exponent of OTOCs
Yingfei Gu, Alexei Kitaev
We derive an identity relating the growth exponent of early-time OTOCs, the pre-exponential factor, and a third number called "branching time". The latter is defined within the dyn…
Spread of entanglement in a Sachdev-Ye-Kitaev chain
Yingfei Gu, Andrew Lucas, Xiao-Liang Qi
We study the spread of Rényi entropy between two halves of a Sachdev-Ye-Kitaev (SYK) chain of Majorana fermions, prepared in a thermofield double (TFD) state. The SYK chain model i…
