AMO/IQSE Seminar: From table-top experiments for quantum gravity to quantum effects in cosmology

AMO/IQSE Seminar: From table-top experiments for quantum gravity to quantum effects in cosmology

Speaker: Yusef Maleki (IQSE, Texas A&M University)Host: IQSE, AMO

Quantization of gravity remains one of the most important, yet extremely elusive, challenges at the heart of modern physics. Any attempt to resolve this long-standing problem seems to be doomed, as the route to any direct empirical evidence (i.e., detecting gravitons) for shedding light on the quantum aspect of gravity [...]
AMO/IQSE seminar: Time-inversion in  quantum metrology

AMO/IQSE seminar: Time-inversion in quantum metrology

Speaker: Luiz Davidovich (Institute for Quantum Science and Engineering, Texas A&M University; Hagler Institute for Advanced Study; Federal University of Rio de Janeiro)

Quantum metrology aims to estimate parameters, like weak electric and magnetic fields, temperature, phases, small displacements, and the time duration of a dynamical process,  with precision beyond that attained by classical metrological methods. The usual procedure involves measuring a probe, prepared in a convenient initial state, after it has interacted [...]
AMO/IQSE seminar: Fluxes and partitioning of heavy metals in large river basins: multidisciplinary research

AMO/IQSE seminar: Fluxes and partitioning of heavy metals in large river basins: multidisciplinary research

Speaker: Galina Shinkareva

Historically aquatic systems are considered as cradles of civilizations and drivers of their evolution. However, the centuries-old use of river systems in anthropogenic activities leads to their severe pollution. The understanding of pollutant transport and sedimentation processes in river basins is crucial for the further development of cities and industries. [...]
AMO/IQSE seminar: Time and Quantum Gravity
September 27, 2022 11:30 am (CDT) MPHY 578 / IQSE Seminar Room
AMO/IQSE seminar: Time and Quantum Gravity

Speaker: William G. Unruh (Canadian Institute for Advanced Research; University of British Columbia; Institute for Quantum Science and Engineering, Texas A&M University; Hagler Institute for Advanced Study )

The very different roles that time plays in Quantum Mechanics and in Gravity seems to be one of the main impediments to developing a quantum theory of gravity. I will review these and the problems they cause each other. Unfortunately I will not give a solution.
