Emergent spacetime supersymmetry at 2D fractionalized quantum criticality
Zhengzhi Wu, Zhou-Quan Wan, Shao-Kai Jian +1
While experimental evidence for spacetime supersymmetry (SUSY) in particle physics remains elusive, condensed matter systems offer a promising arena for its emergence at quantum cr…
Phase transitions in sampling and error correction in local Brownian circuits

We study the emergence of anticoncentration and approximate unitary design behavior in local Brownian circuits. The dynamics of circuit averaged moments of the probability distribu…
Equilibration of Topological Defects Near the Deconfined Quantum Multicritical Point
Yu-Rong Shu, Shao-Kai Jian, Anders W. Sandvik +1
Deconfined quantum criticality (DQC) arises from fractionalization of quasi-particles and leads to fascinating behaviors beyond the Landau-Ginzburg-Wilson description of phase tran…

Shuo Liu, Shi-Xin Zhang, Shao-Kai Jian +1
Variational quantum algorithms (VQAs) hold great potentials for near-term applications and are promising to achieve quantum advantage on practical tasks. However, VQAs suffer from…
Universal chaotic dynamics from Krylov space
Johanna Erdmenger, Shao-Kai Jian, Zhuo-Yu Xian
Krylov complexity measures the spread of the wavefunction in the Krylov basis, which is constructed using the Hamiltonian and an initial state. We investigate the evolution of the…

Measurement-induced phase transitions (MIPT) have attracted increasing attention due to the rich phenomenology of entanglement structures and their relation with quantum informatio…
Holographic measurement and quantum teleportation in the SYK thermofield double
Stefano Antonini, Brianna Grado-White, Shao-Kai Jian +1
According to holography, entanglement is the building block of spacetime; therefore, drastic changes of entanglement will lead to interesting transitions in the dual spacetime. In…
Holographic measurement and bulk teleportation
