The War and Treaty’s Michael and Tanya Trotter grew up in Cleveland, Ohio, and Washington, DC, respectively, but both have family roots in the South. They also grew up in the musical traditions of their churches – Tanya in the Black Baptist Church and Michael in the Seventh Day Adventist Church – where they learned the power of song to move people. After becoming a father at a very young age, Michael eventually joined the armed forces and served in Iraq and Germany, where he took up songwriting as a way of dealing with his experiences there. Meanwhile Tanya embarked on a singing and acting career after a breakthrough appearance in Sister Act 2 alongside Whoopi Goldberg and Lauryn Hill. Now, after a long and sometimes traumatic journey, Michael and Tanya are married, touring, winning all sorts of awards, and set to release their fifth album together, and their fourth as The War and Treaty. Sid talks to Michael and Tanya about the new record, Plus One , as well as their collaboration with Miranda Lambert, what it was like to record at FAME studios in Muscle Shoals, and how they’re blending country, soul, gospel, and R&B.

Episode 81: Pixelated Space Time with Philip Tee 1:02:26

for 25 dage siden1:02:26

1:02:26

Jim talks with Philip Tee about the effects of a fundamental length scale. Phil uses doubly special relativity to try to find observable effects of the pixelization of space, including its effect on light bending and the Casimir effect. Show notes: http://frontiers.physicsfm.com/81

Episode 80: Emergent Decoherent Histories with Philipp Strasberg 1:13:41

for 10 weeks siden1:13:41

1:13:41

Jim talks with Philipp Strasberg about his simulations of branching and recombining processes in the evolution of quantum states, and their meaning for not only for the many worlds interpretation but also for understanding quantum mechanics in general. Show Notes: http://frontiers.physicsfm.com/80

Episode 79: Primordial Black Holes with QCD Color Charge with Elba Alonso-Monsalve and David Kaiser 59:31

for 26 weeks siden59:31

59:31

Jim talks with Elba Alonso-Monsalve and David Kaiser about the prospects to describe dark matter as tiny black holes that were created at the end of cosmic inflation. Due to the large inhomogeneities in the distribution of matter at that time, the black holes could form directly from the matter distribution and not be color neutral (in the sense of QCD).

51:05

Jim talks with Bruna Shinohara of CMC Microsystems. Quantum computing and machine learning are both currently making huge strides. So it is not strange that people are trying to use quantum computing for machine learning.

for 49 weeks siden1:21:10

1:21:10

Jim talks with Alex Jurgens about Maxwellian ratchets, automata that are similar to Maxwell's Demon. They talk about their implications for information processing and entropy. http://frontiers.physicsfm.com/77

Episode 75: Categorical Probability and the Measurement Problem 1:07:24

for 2 years siden1:07:24

1:07:24

Jim talks with Nick Ormrod and V. Vilasini about their use of categorical probability theory to analyze the measurement problem. We discuss categorical probability theory, which allows them to abstract from particular mathematical formulations of quantum mechanics to more general ideas about states and measurements and observers than found in Hilbert space formulations. They use this to look at the various properties of quantum mechanics and how they relate to each other, in particular how relativity affects the measurement problem.

Jim talks with David Wolpert about the non-equilibrium behavior of computation, what it means for entropy, and how it relates to traditional thermodynamics. Show Notes: http://frontiers.physicsfm.com/74

Jim discusses quantum money with Jiahui Liu. Quantum money is a linchpin of quantum cryptography. The ability to create secure banknotes using quantum computers would allow even more secure methods of encryption for communications.

Episode 72: Born Rule and Gravity with Antony Valentini 1:13:54

for 2 years siden1:13:54

1:13:54

Jim talks with Antony Valentini about the difficulties of interpretation of quantum mechanics in light of quantum gravity. In particular, Antony discusses the failure of the Born Rule due to the impossibility of normalization (the fact that probabilities must sum to 100%) at that scale, and therefore the need to interpret the wavefunction as something more than merely the knowledge of the observer about the system. They spend some time talking about the de Broglie-Bohm interpretation in light of quantum gravity. Show Notes: http://frontiers.physicsfm.com/72…

Episode 70: Path Integrals and Entanglement with Ken Wharton 46:30

for 2 years siden46:30

46:30

Jim talks with Ken Wharton about how to describe entangled states as sums over histories of particle paths using the path integral method. He shows how this works for Bell-type experiments, entanglements swapping, delayed choice experiments, and the triangle network. This leads to a second way to describe what happens quantum mechanically without introducing non-locality (but requiring other classical ideas to break down).

Episode 69: The Flavor Puzzle with Joe Davighi 43:00

for 2 years siden43:00

43:00

Jim talks with Joe Davighi of the University of Zurich about the flavor unification at high energies - the merging of all leptons into one kind of particle. The discussion includes symmetries in particle physics, symmetry breaking at low temperatures, and unification schemes in general. Joe also discusses both leptoquarks and proton stability in the context of his theory.…

Episode 68: Quantum Resource Theories with Gilad Gour 51:29

for 2 years siden51:29

51:29

Jim talks with Gilad Gour of the University of Toronto about quantum resource theories. These are theories of largish systems that describe the relationships between possible states by the different levels of resources required for each. By using resources, a system can move from one state to another. This results in a partial order where between two states there could be two different states inaccessible to one another. Although (usually) these coalesce into an order based on a single property of thermodynamically-sized systems, the entropy, a few do not. Show Notes: http://frontiers.physicsfm.com/68…
