Strongly frustrated 2D magnetism in a 3D hexagonal perovskite
Bocheng Yu, Otkur Omar, Songtai Lv +12
Exotic quantum phenomena are often found to occur in spin systems that exhibit low-dimensional magnetism. By combining nuclear magnetic resonance, neutron scattering, and muon-spin…
Giant bubbles of Fisher zeros in the quantum XY chain
Songtai Lv, Yang Liu, Erhai Zhao +2
We demonstrate an alternative approach based on a complex-valued inverse temperature and partition function to probe quantum phases of matter with nontrivial spectra and dynamics.…
Spontaneous Parity Breaking in Quantum Antiferromagnets on the Triangular Lattice
Songtai Lv, Yuchen Meng, Haiyuan Zou
Frustration on the triangular lattice has long been a source of intriguing and often debated phases in many-body systems. Although symmetry analysis has been employed, the role of…
Reducing the Computational Cost Scaling of Tensor Network Algorithms via Field-Programmable Gate Array Parallelism
Songtai Lv, Yang Liang, Rui Zhu +2
Improving the computational efficiency of quantum many-body calculations from a hardware perspective remains a critical challenge. Although field-programmable gate arrays (FPGAs) h…
Detecting Many-Body Scars from Fisher Zeros
Yuchen Meng, Songtai Lv, Yang Liu +3
The far-from-equilibrium dynamics of certain interacting quantum systems still defy precise understanding. One example is the so-called quantum many-body scars (QMBSs), where a set…
Exact Fisher zeros and thermofield dynamics across a quantum critical point
Yang Liu, Songtai Lv, Yuchen Meng +3
By setting the inverse temperature loose to occupy the complex plane, Fisher showed that the zeros of the complex partition function , if approaching the real axis, reve…
Many-body computing on Field Programmable Gate Arrays
Songtai Lv, Yang Liang, Yuchen Meng +5
A new implementation of many-body calculations is of paramount importance in the field of computational physics. In this study, we leverage the capabilities of Field Programmable G…
Signatures of quantum criticality in the complex inverse temperature plane
Yang Liu, Songtai Lv, Yang Yang +1
Concepts of the complex partition functions and the Fisher zeros provide intrinsic statistical mechanisms for finite temperature and real time dynamical phase transitions. We exten…
