SUMMARY:T Serkan Kasirga (Bilkent University): Optoelectronics and phase transitions of atomically thin materials via proximity engineering nbsp
DESCRIPTION:Speaker: T Serkan Kasirga\, Bilkent University\nUnlike three-dimensional materials\, screening of the interaction across quasiparticles in atomically thin materials can significantly alter their electronic and phononic properties. Earlier studies have demonstrated that dielectric screening can modify material parameters\, including electronic mobility\, conductivity\, Raman modes\, Seebeck coefficient\, and photoluminescence\, in semiconducting two-dimensional (2D) materials. In this talk\, I will discuss our efforts on finding novel two-dimensional materials with phase transitions via interlayer space modification and how screening modification via substrate engineering can be used in conjunction with scanning photocurrent microscopy to investigate the fundamental properties of 2D materials\, such as photoresponse mechanisms. Moreover\, I will illustrate how metals can be used to achieve screening\, despite the odds\, at the ultimate proximity to control the excitonic light emission from semiconducting 2D materials. Ultimately\, I will attempt to demonstrate how screening effects can be leveraged to enhance various electronic and optical properties of two-dimensional materials.

SUMMARY:Towards reconfigurable and deterministic twistronic 2D materials
DESCRIPTION:Speaker: Yuan Cao\, University of California at Berkeley\nTwo-dimensional materials (2DM) and their heterostructures offer tunable electrical and optical properties\, primarily modifiable through electrostatic gating and twisting. While electrostatic gating is a well-established method for manipulating 2DM\, achieving real-time control over interfacial properties remains a frontier in exploring 2DM physics and advanced quantum device technology. Current methods\, often reliant on scanning microscopes\, are limited in their application scope\, lacking the accessibility and scalability of electrostatic gating at the device level. In the first half of this seminar\, I will introduce an on-chip platform for 2DM with in situ adjustable interfacial properties\, employing a microelectromechanical system (MEMS). This platform comprises compact\, precise\, and versatile devices capable of voltage-controlled manipulation of 2DM\, including approaching\, twisting\, and pressurizing actions. We demonstrate this technology by creating synthetic topological singularities in the nonlinear optical susceptibility of twisted hexagonal boron nitride (h-BN).In the second half of this seminar\, I will talk about our recent progress in observing symmetry-forbidden second-harmonic generation in almost any 2D crystals\, which is extremely useful for deterministic twistronics. Optical spectroscopy based on second-order nonlinearity is a critical technique for characterizing two-dimensional (2D) crystals\, and it also finds numerous applications in bioimaging and quantum optics. It has been generally believed that second-harmonic generation (SHG) in crystals with inversion centers (centrosymmetric crystals)\, such as graphene and other bilayer 2D crystals\, is negligible without externally breaking the symmetry via strong surface effects. However\, with a new ultra-sensitive detection technique\, we could circumvent the symmetry-imposed constraint and observe robust SHG in pristine centrosymmetric crystals\, even without any symmetry-breaking field. With the exceptional sensitivity\, we directly observe polarization-resolved SHG in bilayer hexagonal boron nitride (h-BN)\, bilayer WSe2\, and remarkably\, Bernal-stacked bilayer graphene\, allowing us to unambiguously identify the crystallographic orientation in all these crystals via SHG. We also demonstrate that the new technique can be used to non-invasively detect uniaxial strain and geometric phase in these centrosymmetric crystals.

SUMMARY:Dr. John Martinis (UC Santa Barbara and Qolab): Prehistoric quantum bits: experiments testing the fundamental physics of superconducting quantum devices
DESCRIPTION:Abstract \n\n\n\nQuantum mechanics was developed to describe the physics of the small\, for fundamental particles\, atoms and molecules. But does it still work for macroscopic systems? My PhD thesis experiment in 1985 tested this idea\, showing the macroscopic current and voltages in a 1 cm chip obey the quantum phenomena of tunneling and energy-level quantization\, proving that a superconducting circuit can behave as a single `artificial atom.’ Over the last four decades\, many physicists around the world have continued research on quantum devices. The field has evolved from fundamental tests into a high-stakes effort to build quantum bits and a quantum computer. At Google\, our ‘quantum supremacy’ experiment was the culmination of this system-level optimization\, proving that a processor could outpace classical supercomputers by maintaining high-fidelity control over a huge computational (Hilbert) space. Now\, at my startup Qolab\, we are leveraging 300mm semiconductor fabrication to achieve the extreme uniformity and yield necessary to build a useful general-purpose quantum computer. \n\n\n\nBio \n\n\n\nJohn M. Martinis is an experimental physicist whose work laid much of the foundation for superconducting quantum circuits. Trained at the University of California\, Berkeley\, he carried out landmark experiments demonstrating macroscopic quantum tunneling and energy quantization in Josephson-junction circuits\, showing that electrical circuits can exhibit fully quantum behavior. As a long-time research scientist at NIST and professor at UC Santa Barbara\, he developed high-coherence superconducting qubits and precision measurement techniques that became standards in the field. He later led Google’s quantum hardware program\, where his team built and operated large-scale superconducting processors and demonstrated quantum computational advantage. More recently\, he co-founded Qolab\, focusing on scalable\, high-performance quantum hardware. His contributions to macroscopic quantum phenomena and superconducting quantum technology were recognized with the 2025 Nobel Prize in Physics.

SUMMARY:: Searching for chiral superconductors using ultrasound
DESCRIPTION:Speaker: Brad Ramshaw\, Cornell University\nFor more than a century\, superconductors have been the paradigmatic ‘quantum material’\, providing fundamental discoveries like gauge symmetry breaking and impacting technologies from medical imaging to quantum computing. Despite their central importance\, characterizing new types of superconductors is still a difficult task: all superconductors have zero resistance\, but their more subtle properties related to entanglement and topology are hard to probe experimentally. I will introduce chiral topological superconductors in two dimensions – a type of superconductivity with a ‘knot’ in the superconducting wave function. These superconductors can host Majorana edge modes and bound states in their vortex cores\, but finding a real-life example has proven challenging. I will show how we use ultrasound – deforming a crystalline lattice in a manner not unlike how gravity waves deform spacetime – to test whether a particular superconductor has the ‘right ingredients’ to be a 2D topological superconductor. I will present the progress we have made thus far – ruling out many proposed candidate materials and discovering an unexpected new type of superconductivity along the way. Most recently\, this has led us to the discovery of a multi-component superconducting state in UTe2 under hydrostatic pressure – a state that may indeed be topological. Finally\, I will give a prognosis for what I think the most promising route is for discovering a 2D topological superconductor.
