Strange Metals from Melting Correlated Insulators in Twisted Bilayer Graphene
Peter Cha, Aavishkar A. Patel, Eun-Ah Kim
Even as the understanding of the mechanism behind correlated insulating states in magic-angle twisted bilayer graphene converges towards various kinds of spontaneous symmetry break…
Attention-based Quantum Tomography
Peter Cha, Paul Ginsparg, Felix Wu +3
With rapid progress across platforms for quantum systems, the problem of many-body quantum state reconstruction for noisy quantum states becomes an important challenge. Recent work…
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…
