We explore an unconventional class of problems in the study of (quantum) critical phenomena, termed “deep boundary criticality”. Traditionally, critical systems are analyzed with two types of perturbations: those uniformly distributed throughout the bulk, which can significantly alter the bulk criticality by triggering a nontrivial bulk renormalization group flow, and those confined to a boundary or subdimensional defect, which affect only the boundary or defect condition. Here, we go beyond this paradigm by studying quantum critical systems with boundary perturbations that decay algebraically (following a power law) into the bulk. By continuously varying the decay exponent, such perturbations can transition between having no effect on the bulk and strongly influencing bulk behavior. We investigate this regime using two prototypical models based on (1+1)D massless Dirac fermions. Through a combination of analytical and numerical approaches, we uncover exotic scaling laws in simple observables and observe qualitative changes in model behavior as the decay exponent varies.

APS March Meeting in Hong Kong | March 16–22, 2025 The Physical Society of Hong Kong and the American Physical Society have agreed to hold a satellite conference in Hong Kong during the APS March Meeting from March 16 to 22, 2025. Some academic presentations made at the Hong Kong venue will be simultaneously broadcasted to the online platform of the APS March Meeting. Attendees can also view presentations from the APS online platform. This conference provides a valuable platform for researchers who are unable to attend the meeting in the United States due to visa issues. It offers them the opportunity to showcase their research achievements and engage in academic exchanges with international collaborators. Conference Organization: Host Organization: Physical Society of Hong Kong Co-organizer: American Physical Society | HK Institute of Quantum Science & Technology Organizing Institutions: City University of Hong Kong | Qebula Mind Limited Conference Chairs: Professor Xunli Wang: Chair Professor, Department of Physics, City University of Hong Kong | Board Member and International Councilor, American Physical Society Professor Zidan Wang: Chair Professor, Department of Physics, University of Hong Kong | Chairman of the Council, Physical Society of Hong Kong Professor Bei Zeng: Professor, Department of Physics, Hong Kong University of Science and Technology | President, Physical Society of Hong Kong Conference Committee Members: Sunny Xin Wang Xiao Li Zhedong Zhang Liang Dai Conference Secretary: Sunny Wang Xin: Department of Physics, City University of Hong Kong | Honorary Treasurer, Physical Society of Hong Kong Jointly Organized by: APS, HK Physical Society of Hong Kong, HK Institute of Quantum Science & Technology, City University of Hong Kong, and Qebula Mind Limited
