Sp(2N, R) interferometry in multi-mode Gaussian bosonic systems for optimal metrology and quantum control
Chenwei Lv, Renbao Liu
Multi-mode interferometers for bosons in Gaussian states are important systems for quantum metrology with precision beyond the standard quantum limit and for bosonic quantum comput…
Efimovian Phonon Production for an Analog Coasting Universe in Bose-Einstein Condensates
Yunfei Xue, Jiabin Wang, Li Chen +2
Efimov effects arise from scale invariance, a fundamental symmetry with universal implications. While spatial Efimov physics has been extensively studied, realizing its temporal co…
Polarization-dependent chiral transport and chiral solitons in spin Kitaev models
Chenwei Lv, Thomas Bilitewski, Ana Maria Rey +1
Recent advances in synthetic quantum matter allow researchers to design quantum models inaccessible in traditional materials. Here, we propose protocols to engineer a new class of…
Geometric Optimization of Quantum Control with Minimum Cost
Chengming Tan, Yuhao Cai, Jinyi Zhang +3
We investigate the optimization of quantum control from a differential geometric perspective. In our approach, optimal control minimizes the cost associated with evolving a quantum…
Hidden curved spaces in Bosonic Kitaev model
Chenwei Lv, Qi Zhou
Quantum matter in curved spaces exhibits remarkable properties unattainable in flat spaces. To access curved spaces in laboratories, the conventional wisdom is that physical distor…
Synthetic tensor gauge fields

Synthetic gauge fields have provided physicists with a unique tool to explore a wide range of fundamentally important phenomena. However, most experiments have been focusing on syn…
Multipolar condensates and multipolar Josephson effects
Wenhui Xu, Chenwei Lv, Qi Zhou
When single-particle dynamics are suppressed in certain strongly correlated systems, dipoles arise as elementary carriers of quantum kinetics. These dipoles can further condense, p…
Nanophotonic cavity cooling of a single atom
Chenwei Lv, Ming Zhu, Sambit Banerjee +1
We investigate external and internal dynamics of a two-level atom strongly coupled to a weakly pumped nanophotonic cavity. We calculate the dipole force, friction force, and stocha…
Building Krylov complexity from circuit complexity
Chenwei Lv, Ren Zhang, Qi Zhou
Krylov complexity has emerged as a new probe of operator growth in a wide range of non-equilibrium quantum dynamics. However, a fundamental issue remains in such studies: the defin…
Emergent spacetimes from Hermitian and non-Hermitian quantum dynamics
Chenwei Lv, Qi Zhou
We show that quantum dynamics of any systems with symmetry give rise to emergent Anti-de Sitter spacetimes in 2+1 dimensions (AdS). Using the continuous circuit d…
Universal relations for dilute systems with two-body decays in reduced dimensions
Mingyuan He, Chenwei Lv, Qi Zhou
Physical systems in reduced dimensions exhibit intriguing properties. For instance, the dependences of two-body and many-body physics on scattering lengths are distinct from their…
Analogue Black Holes in Reactive Molecules
Ren Zhang, Chenwei Lv, Qi Zhou
We show that reactive molecules with a unit probability of reaction naturally provide a simulator of some intriguing black hole physics. The unit reaction at the short distance act…
Quantum Dynamics of Cold Atomic Gas with Symmetry
Jing Zhang, Xiaoyi Yang, Chenwei Lv +2
Motivated by recent advances in quantum dynamics, we investigate the dynamics of the system with symmetry. Instead of performing the time-ordered integral for the evoluti…
Curving the space by non-Hermiticity
Chenwei Lv, Ren Zhang, Zhengzheng Zhai +1
Quantum systems are often classified into Hermitian and non-Hermitian ones. Extraordinary non-Hermitian phenomena, ranging from the non-Hermitian skin effect to the supersensitivit…
