Another preprint (arxiv:2607.13262). We introduce transient depth thermography, a non-contact optical approach that exploits wavelength-dependent optical penetration depth to reconstruct spatiotemporal temperature profiles and quantify out-of-plane thermal conductivity and interfacial thermal resistance. We demonstrate the method in fused silica and MgF2 and further show through simulations its extension to multilayer thin films for probing interfacial thermal resistance. This is a collaboration work with Prof. Nandika D'Souza's group at UT-Dallas. Congratulations to Dmytro and Chun!

The first preprint from our group in 2026 is now on arXiv (arxiv:2607.10577). In this work, we theoretically investigate the temporal evolution and amplification of thermal (blackbody) radiation in a photonic time crystal. We show that the spatial spectra of initially blackbody radiation converge periodically toward Gaussian profiles with progressively increasing amplitudes, coherence lengths, and spatial- and wavenumber-domain purities. Congrats to Luis, Naren, and Jack!
