Linear resistivity and Sachdev-Ye-Kitaev (SYK) spin liquid behavior in a quantum critical metal with spin- fermions
Peter Cha, Nils Wentzell, Olivier Parcollet +2
`Strange metals' with resistivity depending linearly on temperature down to low- have been a long-standing puzzle in condensed matter physics. Here, we consider a model of i…
Robust increase in supply by vessel dilation in globally coupled microvasculature
Felix J. Meigel, Peter Cha, Michael P. Brenner +1
Neuronal activity induces changes in blood flow by locally dilating vessels in the brain microvasculature. How can the local dilation of a single vessel increase flow-based metabol…
-linear resistivity in models with local self-energy
Peter Cha, Aavishkar A. Patel, Emanuel Gull +1
A theoretical understanding of the enigmatic linear-in-temperature () resistivity, ubiquitous in strongly correlated metallic systems, has been a long sought-after goal. Further…
Extensions of Theories from Soft Limits
Freddy Cachazo, Peter Cha, Sebastian Mizera
We study a variety of field theories with vanishing single soft limits. In all cases, the structure of the soft limit is controlled by a larger theory, which provides an extension…
