|Interacting quantum many-body systems pose interesting and important challenges to the condensed-matter physics research. Numerical methods have become important tools to study quantum many-body physics. Recently, rapid developments inspired by quantum information science and machine learning have improved the efficiency and accuracy of the simulations. This enables physicists to study more complicated systems.
In this panel, we will bring together experts on the application of quantum Monte Carlo, tensor network states, and machine learning to quantum many-body systems to present and discuss their own research.
Low Carbon and Green Energy

|Energy issues have recently become globally important public concerns, and low-carbon green energy will play a key role in the era of the Third Industrial Revolution. Taiwan’s dependence on imported fossil fuels is still high, with an energy self-sufficiency rate of only 1-2%. Although Taiwan has recently ranked among the top Asian countries in the World Competitiveness Yearbook, published by the International Institute for Management Development (IMD) (Lausanne, Switzerland), Taiwan is still lagging behind many other countries in renewable energy use. Furthermore, the global risk assessment of catastrophic losses, published by the Intergovernmental Panel on Climate Change (IPCC), ranked Taiwan as the fourth most vulnerable country. To reduce global greenhouse gas (GHG) emissions in response to globalization and increasingly stringent carbon emission policies, such as the Paris Agreement, adopted in 2015 at the 21st Conference of the Parties (COP21) of the United Nations Framework Convention on Climate Change (UNFCCC), Taiwan must follow the trend of energy transformation and establish green energy technologies. In light of the recent rapid development of novel functional materials for energy in Taiwan, our forum will focus on the theme of "low-carbon green energy.” We aim to accelerate the research and development of energy technologies in our country to improve Taiwan’s international scholarly and practical status. This will be achieved through multilateral exchange and integration between different scientific disciplines (including nanoscience, semiconductor, optics, and optoelectronics), as well as cross-university and cross-disciplinary horizontal and vertical integration of research and knowledge. We also seek to achieve Taiwan’s goals for the development of renewable energy.

|Complex oxides are gifted systems which have caught great attention in the past decade. The interplays of lattice, charge, orbital, and spin degrees of freedom, leading to novel (and exotic) ground states due to correlated electrons in complex oxides result in lots of emergent physical phenomena and cover a broad spectrum of intriguing functionalities, such as high temperature superconductivity, multiferroics, colossal magneto-resistance, and offer tremendous opportunities for next-generation electronic devices. In this panel, domestic and international experts in this research field will gather together to share their recent progress.
