题目:Non-Hermitian Parent Hamiltonian and Composite Quantum Phases | 青年科学半月谈 时间:2023年4月27日(周四)10:00 报告人:Yuchen Guo Abstract: In this talk, I plan to introduce our two recent works (arXiv: 2301.12448, arXiv: 2304.04588) on non-Hermitian interacting spin systems. I will be...
Dielectric microcavityLamb shiftWhispering gallery modeEffective potential wellWe study the normal modes and quasi-normal modes (QNMs) in circular dielectric microcavities through non-Hermitian Hamiltonian, which come from the modifications due to system鈥揺nvironment coupling. Differences between the two...
Hamiltonians having this property need not be Hermitian, but, except when PCT is spontaneously broken, the energy levels of such Hamiltonians are all real and positive! In this talk I examine quantum mechanical and quantum field theoretic systems whose Hamiltonians are non-Hermitian but obey PCT...
It is shown that the degree and type of such an instability are controlled by the environment-induced anti-Hermitian terms in Hamiltonians. Using the quantum-statistical approach for non-Hermitian Hamiltonians and related non-linear master equation, we derive the equations that are necessary to ...
