The Conjugate Composite Fermi Liquid
Nayan Myerson-Jain, Chao-Ming Jian, Cenke Xu
Recent experimental observations of the fractional quantum anomalous Hall effect in spin/valley polarized moiré systems call for a more expansive theoretical exploration of strongl…
Intertwined fractional quantum anomalous Hall states and charge density waves
Xue-Yang Song, Chao-Ming Jian, Liang Fu +1
Motivated by the recent experimental breakthrough on the observation of the fractional quantum anomalous Hall (FQAH) effects in semiconductor and graphene moiré materials, we explo…
Disorder Operator and Rényi Entanglement Entropy of Symmetric Mass Generation
Zi Hong Liu, Yuan Da Liao, Gaopei Pan +8
In recent years a consensus has gradually been reached that the previously proposed deconfined quantum critical point (DQCP) for spin-1/2 systems, an archetypal example of quantum…
Realizing a tunable honeycomb lattice in ABBA-stacked twisted double bilayer WSe
Haining Pan, Eun-Ah Kim, Chao-Ming Jian
The ideal honeycomb lattice, featuring sublattice and SU(2) spin rotation symmetries, is a fundamental model for investigating quantum matters with topology and correlations. With…
Higher-form Symmetries under Weak Measurement
Kaixiang Su, Nayan Myerson-Jain, Chong Wang +2
We aim to address the following question: if we start with a quantum state with a spontaneously broken higher-form symmetry, what is the fate of the system under weak local quantum…
Subsystem symmetry, spin glass order, and criticality from random measurements in a two-dimensional Bacon-Shor circuit
Vaibhav Sharma, Chao-Ming Jian, Erich J Mueller
We study a 2D measurement-only random circuit motivated by the Bacon-Shor error correcting code. We find a rich phase diagram as one varies the relative probabilities of measuring…
Measurement-induced entanglement transitions in quantum circuits of non-interacting fermions: Born-rule versus forced measurements
Chao-Ming Jian, Hassan Shapourian, Bela Bauer +1
We address entanglement transitions in monitored random quantum circuits of non-interacting fermions, in particular, the question of whether Born-rule and forced measurements yield…
Entanglement in one-dimensional critical state after measurements
Zhou Yang, Dan Mao, Chao-Ming Jian
The entanglement entropy (EE) of the ground state of a one-dimensional Hamiltonian at criticality has a universal logarithmic scaling with a prefactor given by the central charge $…
Quantum criticality under decoherence or weak measurement
Jong Yeon Lee, Chao-Ming Jian, Cenke Xu
Decoherence inevitably happens when a quantum state is exposed to its environment, which can affect quantum critical points (QCP) in a nontrivial way. As was pointed out in recent…
