Linear Magnetoresistance from Glassy Orders
Jaewon Kim, Ehud Altman, Shubhayu Chatterjee
Several strongly correlated metals display B-linear magnetoresistance (LMR) with a universal slope, in sharp contrast to the scaling predicted by Fermi liquid theory. We prov…
Error Threshold of SYK Codes from Strong-to-Weak Parity Symmetry Breaking
Jaewon Kim, Ehud Altman, Jong Yeon Lee
Quantum error correction (QEC) codes are fundamentally linked to quantum phases of matter: the degenerate ground state manifold corresponds to the code space, while topological exc…
Computational Phase Transitions in Two-Dimensional Antiferromagnetic Melting
Zack Weinstein, Jalal Abu Ahmad, Daniel Podolsky +1
A computational phase transition in a classical or quantum system is a non-analytic change in behavior of an order parameter which can only be observed with the assistance of a non…
Magnetization amplification in the interlayer pairing superconductor 4Hb-TaS
Chunxiao Liu, Shubhayu Chatterjee, Thomas Scaffidi +2
A recent experiment on the bulk compound 4Hb-TaS reveals an unusual time-reversal symmetry-breaking superconducting state that possesses a magnetic memory not manifest in the n…
Measurements conspire nonlocally to restructure critical quantum states
Samuel J. Garratt, Zack Weinstein, Ehud Altman
We study theoretically how local measurements perfomed on critical quantum ground states affect long-distance correlations. These states are highly entangled and feature algebraic…
Theory of a Strange Metal in a Quantum Superconductor to Metal Transition
Jaewon Kim, Erez Berg, Ehud Altman
Recent experiments with nanopatterned thin films revealed an unusual quantum superconductor to metal phase transition (QSMT) with a linear in temperature resistivity. In contrast,…
