SUMMARY:High rank multipole order feeling the strain\, Ian Fisher
DESCRIPTION:Speaker: Ian Fisher\, Stanford University\nInteractions can lead to a wide variety of ordered states in materials. Phase transitions in which local atomic states develop spontaneous high rank multipole order provides a particularly rich arena for new insights. A key element in the study of such systems is the ability to couple to the associated order parameter. At its heart\, this colloquium will be about symmetry and thermodynamics.I will describe how one can couple to a variety of different multipolar states\, motivating new methodologies to measure a fundamental thermodynamic material property\, the multipole susceptibility. One can also identify effective transverse fields\, which\, when applied inside the ordered state\, induce quantum fluctuations and can drive a multipolar quantum phase transition. I will explain the very special roles that strain can play for each of the cases\, and will outline new experimental approaches in which the materials ‘feel the strain’ in different ways.Even while we manipulate the crystal lattice to tune electronic order\, hyperfine interactions are not always completely innocent. Along the way I will introduce the special case of an electro-nuclear quantum phase transition.And finally\, the confluence of new measurement techniques and new materials also leads to possibilities for new applications; I will briefly outline one such application\, based on a giant elastocaloric effect. Multipolar order\, it would seem\, is not only interesting from a fundamental perspective\, but can also be useful. Video Link (requires UW NetID)

SUMMARY:Separating QMA and QCMA with a classical oracle\, Chinmay Nirkhe
DESCRIPTION:Abstract:  \n\n\n\nWe construct a classical oracle proving that\, in a relativized setting\, the set of languages decidable by an efficient quantum verifier with a quantum witness (QMA) is strictly bigger than those decidable with access only to a classical witness (QCMA). The separating classical oracle we construct is for a decision problem we coin spectral Forrelation — the oracle describes two subsets of the boolean hypercube\, and the computational task is to decide if there exists a quantum state whose standard basis measurement distribution is well supported on one subset while its Fourier basis measurement distribution is well supported on the other subset. This is equivalent to estimating the spectral norm of a “Forrelation” matrix between two sets that are accessible through membership queries. \n\n\n\nOur lower bound derives from a simple observation that a query algorithm with a classical witness can be run multiple times to generate many samples from a distribution\, while a quantum witness is a “use once” object. This observation allows us to reduce proving a QCMA lower bound to proving a sampling hardness result\, which does not simultaneously prove a QMA lower bound. To prove said sampling hardness result for QCMA\, we observe that quantum access to the oracle can be compressed by expressing the problem in terms of bosons — a novel “second quantization” perspective on compressed oracle techniques\, which may be of independent interest. Using this compressed perspective on the sampling problem\, we prove the sampling hardness result\, completing the proof. \n\n\n\nJoint work with John Bostanci\, Jonas Haferkamp\, and Mark Zhandry: https://arxiv.org/abs/2511.09551
