Click, Watch, Learn: The Impact of Student Self-Study Materials on Physics E&M Course Outcomes
Performance in introductory courses, particularly physics, is often crucial for student success in STEM majors and can impact an individual's tendency to persist in their chosen field. To enhance students' individual learning experiences, faculty at many universities have worked to develop open-access, self-study materials to help build conceptual understanding and problem-solving skills. Faculty at Texas A&M University have contributed to these efforts, creating more than 200 online video reso…

Non-Orthogonal Affine Frequency Division Multiplexing for Spectrally Efficient High-Mobility Communications
This paper proposes a novel non-orthogonal affine frequency division multiplexing {(nAFDM)} waveform for reliable high-mobility communications with enhanced spectral efficiency {(SE)}. The key idea is {to introduce} a bandwidth compression factor into the AFDM {modulator} to enable controllable subcarrier overlapping. We first {detail the proposed nAFDM transceiver} and derive the corresponding input-output {signal} relationship. Then, an efficient {nAFDM} signal generation method based on the …

Theory of bound magnetic polarons in cubic and uniaxial antiferromagnets
Motivated by a recent debate about the origin of remanent magnetization and the corresponding anomalous Hall effect in antiferromagnets and their subclass, altermagnets, a theory of bound magnetic polarons (BMPs) in anisotropic antiferromagnetic semiconductors is developed. The theory describes quantitatively the experimentally observed magnitude of excess magnetization and its dependence on the magnetic field in cubic antiferromagnetic EuTe. In contrast to the cubic case, our theory predicts t…
