Universal Short-Imaginary-Time Quantum Critical Dynamics Near Boundaries
Yu-Rong Shu, Yuan-Biao Li, Shuai Yin
While imaginary-time evolution has long served as a standard paradigm for ground-state preparation in numerical simulations and quantum devices, its intrinsic dynamical properties…
Universal Driven Critical Dynamics near the Boundary
Yu-Rong Shu, Shuai Yin
The celebrated Kibble-Zurek mechanism (KZM) describes the scaling of physical quantities when external parameters sweep through a critical point. Boundaries are ubiquitous in real…
Finite-time scaling with two characteristic time scales: Driven critical dynamics with emergent symmetry
Yu-Rong Shu, Li-Ying Yang, Shuai Yin
Critical points with emergent symmetry exhibit intriguing scaling properties induced by two divergent length scales, attracting extensive investigations recently. We study the driv…
Scaling corrections in driven critical dynamics: Application to a two-dimensional dimerized quantum Heisenberg model
Jing-Wen Liu, Shuai Yin, Yu-Rong Shu
Driven critical dynamics in quantum phase transitions holds significant theoretical importance, and also practical applications in fast-developing quantum devices. While scaling co…

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…

Zhi-Xuan Li, Shuai Yin, Yu-Rong Shu
We explore the imaginary-time relaxation dynamics near quantum critical points with semi-ordered initial states. Different from the case with homogeneous ordered initial states, in…
Dual dynamic scaling in deconfined quantum criticality
Yu-Rong Shu, Shuai Yin
Emergent symmetry is one of the characteristic phenomena in deconfined quantum critical point (DQCP). As its nonequilibrium generalization, the dual dynamic scaling was recently di…
Nonequilibrium dynamics in deconfined quantum critical point revealed by imaginary-time evolution
Yu-Rong Shu, Shao-Kai Jian, Shuai Yin
As proposed to describe putative continuous phase transitions between two ordered phases, the deconfined quantum critical point (DQCP) goes beyond the prevalent Landau-Ginzburg-Wil…
Short-imaginary-time quantum critical dynamics in the J-Q spin chain
