Charge and Entanglement Criticality in a U(1)-Symmetric Hybrid Circuit of Qubits
Ahana Chakraborty, Kun Chen, Aidan Zabalo +2
We study critical properties of the entanglement and charge-sharpening measurement-induced phase transitions in a non-unitary quantum circuit evolving with a U(1) conserved charge.…
Precursory Cooper Flow in Ultralow-Temperature Superconductors
Pengcheng Hou, Xiansheng Cai, Tao Wang +4
Superconductivity at low temperature -- observed in lithium and bismuth, as well as in various low-density superconductors -- calls for developing reliable theoretical and experime…
Origin of the Coulomb Pseudopotential
Tao Wang, Xiansheng Cai, Kun Chen +2
We address the outstanding problem of electron pairing in the presence of strong Coulomb repulsion at small to moderate values of the Coulomb parameter, , and demon…
Dynamic Response of an Electron Gas: Towards the Exact Exchange-Correlation Kernel
James P. F. LeBlanc, Kun Chen, Kristjan Haule +2
Precise calculations of dynamics in the homogeneous electron gas (jellium model) are of fundamental importance for design and characterization of new materials. We introduce a diag…
Exchange-correlation effect in the charge response of a warm dense electron gas
Peng-Cheng Hou, Bao-Zong Wang, Kristjan Haule +2
The study of warm dense matter, widely existing in nature and laboratories, is challenging due to the interplay of quantum and classical fluctuations. We develop a variational diag…
Entanglement and charge-sharpening transitions in U(1) symmetric monitored quantum circuits
Utkarsh Agrawal, Aidan Zabalo, Kun Chen +5
Monitored quantum circuits can exhibit an entanglement transition as a function of the rate of measurements, stemming from the competition between scrambling unitary dynamics and d…
