CFT from TQFT via Holographic Tensor Network, and Precision Discretisation of CFT
Lin Chen, Haochen Zhang, Kaixin Ji +4
We show that the path-integral of conformal field theories in dimensions (CFT) can be constructed by solving for eigenstates of an RG operator following from the Turaev-Vir…
Exploring quantum phase transitions by the cross derivative of the ground state energy
H. Y. Wu, Yu-Chin Tzeng, Z. Y. Xie +2
In this work, the cross derivative of the Gibbs free energy, initially proposed for phase transitions in classical spin models [Phys. Rev. B 101, 165123 (2020)], is extended for qu…
Spatiotemporal scaling of two-dimensional nonequilibrium exciton-polariton systems with weak interactions
Quanyu Mei, Kai Ji, Michiel Wouters
We perform a numerical study on the two-dimensional nonequilibrium exciton-polariton systems driven by incoherent pumping based on the stochastic generalized Gross-Pitaevskii equat…
Cross derivative: a universal and efficient method for phase transitions in classical spin models
Y. Chen, K. Ji, Z. Y. Xie +1
With an auxiliary weak external magnetic field, we reexamine the fundamental thermodynamic function, Gibbs free energy F(T, h), to study the phase transitions in the classical spin…
Suppression of heating in quantum spin clusters under periodic driving as a dynamic localization effect
Kai Ji, Boris V. Fine
We investigate numerically and analytically the heating process in ergodic clusters of interacting spins 1/2 subjected to periodic pulses of external magnetic field. Our findings i…
Kadec-Klee property for convergence in measure of noncommutative Orlicz spaces
Zhenhua Ma, Lining Jiang, Kai Ji
In this paper, we study the Kadec-Klee property for convergence in measure of noncommutative Orlicz spaces , where is a vo…
