报告摘要
We explore the physics of the extended Bose-Hubbard model under the action of down-conversion-type Hamiltonians which break particle-number conservation, but keep interesting Z2 or U(1) symmetries. The bare model presents a variety of phases ranging from superfluid to insulating. We show that the introduction of downconversion terms potentially adds more phases, e.g., predicting Ising-type spontaneous symmetry breaking or supersolid-like behavior. As a side-product, we provide an example of a single-mode Hamiltonian that presents a continuous quantum phase transition, a result that challenges the common intuition that only infinite-size systems present such behavior. Our model is in the same universality class as the Dicke, Lipkin-Meshkov-Glick, and quantum Rabi models. We explore the possibility of implementing our ideas in moderns platforms such as superconducting circuits or optical lattices.
个人简介
Carlos Navarrete-Benlloch studied Theoretical Physics at the University of Valencia, where he got his PhD in Quantum Optics in 2011, for work developed partially at the Max-Planck Institute for Quantum Optics (Germany), the Massachusetts Institute of Technology (USA), and Swinburne University (Australia). In 2012 he joined Ignacio Cirac’s theory division at the Max-Planck Institute for Quantum Optics, until 2016, when he became Group Leader at Florian Marquardt's theory division at the Max-Planck Institute for the Science of Light (Germany). Since April 2019 he is an Associate Professor at the Wilczek Quantum Center of Shanghai Jiao Tong University. His research lies at the interface between quantum optics, phase transitions, and quantum information.
会议简介
会议名称：量子模拟和量子器件2019国际会议
会议地点：北京
主办方：中国科学院理论物理研究所The Workshop is hosted by Peng-Huan-Wu Research Center of the Institute of Theoretical Physics, Chinese Academy of Sciences at its South Building at Zhong Guan Cun east street 55, during the time period from November 18 to 23, 2019.
The workshop aims to bring together leading scientists at the forefront of quantum simulation and quantum devices, to discuss recent progress and new directions in this interdisciplinary field. The first three days was reserved to introductory tutorials aimed to students and young researchers. Cutting- edge research topics was covered by invited and contributed talks over the remaining days of the conference.
