Quantum error as an emergent magnetic field
Shao-Kai Jian, Chunxiao Liu, Xiao Chen +2
We investigate the effect of quantum errors on a monitored Brownian Sachdev-Ye-Kitaev (SYK) model featuring a measurement-induced phase transition that can be understood as a symme…
Frustrated Heisenberg model within the stretched diamond lattice of LiYbO2
Mitchell M. Bordelon, Chunxiao Liu, Lorenzo Posthuma +7
We investigate the magnetic properties of LiYbO, containing a three-dimensionally frustrated, diamond-like lattice via neutron scattering, magnetization, and heat capacity meas…
Non-unitary dynamics of Sachdev-Ye-Kitaev chain
Chunxiao Liu, Pengfei Zhang, Xiao Chen
We construct a series of one-dimensional non-unitary dynamics consisting of both unitary and imaginary evolutions based on the Sachdev-Ye-Kitaev model. Starting from a short-range…
Spin excitations in the frustrated triangular lattice antiferromagnet NaYbO
Mitchell Bordelon, Chunxiao Liu, Lorenzo Posthuma +6
Here we present a neutron scattering-based study of magnetic excitations and magnetic order in NaYbO under the application of an external magnetic field. The crystal electric f…
Subsystem Rényi Entropy of Thermal Ensembles for SYK-like models
Pengfei Zhang, Chunxiao Liu, Xiao Chen
The Sachdev-Ye-Kitaev model is an -modes fermionic model with infinite range random interactions. In this work, we study the thermal Rényi entropy for a subsystem of the SYK mod…
Competing orders in pyrochlore magnets from a spin liquid perspective
Chunxiao Liu, Gábor B. Halász, Leon Balents
The pyrochlore materials have long been predicted to harbor a quantum spin liquid, an intrinsic long-range-entangled state supporting fractionalized excitations. Existing pyrochlor…
