Universal imaginary-time critical dynamics on a quantum computer
Shi-Xin Zhang, Shuai Yin
Quantum computers promise a highly efficient approach to investigate quantum phase transitions, which describe abrupt changes between different ground states of many-body systems.…
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…

Yuzhi Liu, Zi Yang Meng, Shuai Yin
The fluctuations of massless Dirac fermion can not only turn a first-order bosonic phase transition (in the Landau sense) to a quantum critical point, but also work reversely to en…

Shao-Kai Jian, Shuai Yin
We consider a heterostructure of semiconductor layers sandwiched between two superconductors, forming a two-dimensional Josephson junction. Applying a Zeeman field perpendicular to…
