Interface vs. wavelength size effects unfortunately preclude the measurement of phonons by traditional spectroscopic techniques, making it difficult to unravel the primary excitations of the lattice and the symmetries that they represent across these functional interfaces. In this work, we employed synchrotron-based near-field infrared nanospectroscopy to image 180\u25e6 polar domain walls in multiferroic Ni_3 TeO_6. This is a unique platform because, in addition to hosting polar and chiral domains that are interlocked with one another, Ni_3 TeO_6 displays both charged and neutral interfaces depending upon the direction allowing the development of structure-property relations. Comparison of the contour, fixed distance, and fixed frequency plots reveals that charged walls are twice as wide as (and less stable than) the neutral interfaces due to additional strain created by the on-end chiral helices. Chirality is responsible for much of the interface stiffness and the hardening of certain phonons at the walls. The largest frequency shift, for instance, takes place in a mode consisting of a NiO_6 octahedral contraction and rotation along c, modifying the force constant by approximately 1%. Frequency shifts at walls of both types indicate that polarization switches via an Ising-type mechanism due to structural constraints associated with interlocked chirality. Our estimates also reveal that phonon lifetimes are on the order of 1 ps or less, with marked changes at the charged and neutral walls. The ability to quantify the consequences of charge accumulation at a functional interface in terms of phonon lifetimes opens new avenues for heat management in domain wall-based devices.\n\nReference: A.

treat AI as just another form of capital and predict a slowly evolving world, while computer science scaling laws applied to the whole economy predict explosive growth and the potential for a singularity-like event. Both views gloss over the asymmetric reality that intelligence capital or AI scales at computer-science speeds, whereas physical capital and labor do not. What\u2019s missing is a unified, parameter-driven framework that can nest assumptions from both economics and computer science to generate meaningful predictions of AI\u2019s wage and output impacts. Here we use a constant elasticity of substitution (CES) production function framework that separates physical and intelligence sectors. Whereas physical capabilities let us affect the world, intelligence capabilities let us do this as well: The two are complementary. Given complementarity between the two sectors, the marginal returns to intelligence saturate, no matter how fast AI scales. Because the price of AI capital is falling much faster than that of physical capital, intelligence tasks are automated first, pushing human labor toward the physical sector. The impact of automation on wages is theoretically ambiguous and can be non-monotonic in the degree of automation. A necessary condition for automation to decrease wages is that the share of employment in the intelligence sector decreases; this condition is not sufficient because automation can raise output enough to offset negative reallocation effects. In our baseline simulation, wages increase and then decrease with automation. Our interactive tool shows how parameter changes shift that trajectory. Wage decreases are steeper at high levels of automation when the outputs of the physical and intelligence sectors are more substitutable. After full automation, more AI and more physical capital increase wages, a classic prediction from standard production functions in capital and labor. Yet, when intelligence and physical are complementary, the marginal wage impact of AI capital saturates as AI grows large. More broadly, the model offers a structured way to map contrasting intuitions from economics and computer science into a shared parameter space, enabling clearer policy discussions and guiding empirical work to identify which growth and wage trajectories are plausible.", "occurrence_notes":null, "guid":"143691-21893653@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/143691", "building_id":"1005177", "building_name":"North Quad", "campus_maps_id":"553", "room":"4325", "location_name":"North Quad", "has_livestream":0, "cost":"", "tags":["seminar","Labor","Economics"], "website":"http:\/\/www.lsa.umich.edu\/econ", "sponsors":[ { "group_name":"Department of Economics", "group_id":"3302", "website":"http:\/\/www.lsa.umich.edu\/econ" }, { "group_name":"ISR-Zwerdling Seminar in Labor Economics", "group_id":"3551", "website":"" }, { "group_name":"Department of Economics Seminars", "group_id":"3566", "website":"" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/01\/event_143691_original-1.png", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_thumb\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/01\/event_143691_original-1.png", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/group_thumb\/media\/attachments\/2026\/01\/event_143691_original-1.png", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/group_thumb_square\/media\/attachments\/2026\/01\/event_143691_original-1.png", "group_large":"https:\/\/events.umich.edu\/media\/cache\/group_large\/media\/attachments\/2026\/01\/event_143691_original-1.png", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/group_large_lightbox\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/event_large_crop\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_list":"https:\/\/events.umich.edu\/media\/cache\/event_list\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/event_grid_2x\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/event_feature_large\/media\/attachments\/2026\/01\/event_143691_original-1.png", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/01\/event_143691_original-1.png" }, "occurrence_count":1, "first_occurrence":21893653 } , "146323-21898879": { "datetime_modified":"20260309T040203", "datetime_start":"20260311T143000", "datetime_end":"20260311T153000", "has_end_time":1, "date_start":"2026-03-11", "date_end":"2026-03-11", "time_start":"14:30:00", "time_end":"15:30:00", "time_zone":"America\/Detroit", "event_title":"Learning seminar in algebraic combinatorics: The Fundamental Theorem of Finite Semidistributive Lattices", "occurrence_title":"", "combined_title":"Learning seminar in algebraic combinatorics: The Fundamental Theorem of Finite Semidistributive Lattices: Ming Yean Lim", "event_subtitle":"Ming Yean Lim", "event_type":"Workshop \/ Seminar", "event_type_id":"21", "description":"Last time, we saw that the lattice of torsion classes is completely semidistributive.

Time permitting, we will also describe canonical join representations and the canonical join complex of a finite semidistributive lattice.", "occurrence_notes":null, "guid":"146323-21898879@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/146323", "building_id":"1000166", "building_name":"East Hall", "campus_maps_id":"53", "room":"4088", "location_name":"East Hall", "has_livestream":0, "cost":"", "tags":["Mathematics"], "website":"", "sponsors":[ { "group_name":"Learning Seminar in Algebraic Combinatorics - Department of Mathematics", "group_id":"4894", "website":"" }, { "group_name":"Department of Mathematics", "group_id":"3791", "website":"" } ], "image_url":"", "styled_images":{ "event_thumb":"", "event_large":"", "event_large_2x":"", "event_large_lightbox":"", "group_thumb":"", "group_thumb_square":"", "group_large":"", "group_large_lightbox":"", "event_large_crop":"", "event_list":"", "event_list_2x":"", "event_grid":"", "event_grid_2x":"", "event_feature_large":"", "event_feature_thumb":"" }, "occurrence_count":1, "first_occurrence":21898879 } }
