On window theorem for categorical Donaldson-Thomas theories on local surfaces and its applications

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: In this paper, we prove a window theorem for categorical Donaldson-Thomas theories on local surfaces as an analogue of window theorem for GIT quotient stacks. We give two applications of our main result. The first one is a proof of […]

Beyond Quality and Quantity: Contact Distribution Encodes Frictional Strength

Kavli Affiliate: Shmuel M. Rubinstein | First 5 Authors: Sam Dillavou, Yohai Bar Sinai, Michael P Brenner, Shmuel M Rubinstein, | Summary: Classically, the quantity of contact area $A_R$ between two bodies is considered a proxy for the force of friction. However, bond density across the interface – quality of contact – is also relevant, […]

Cobordism Conjecture in AdS

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Hirosi Ooguri, Tadashi Takayanagi, , , | Summary: McNamara and Vafa conjectured that any pair of consistent quantum gravity theories can be connected by a domain wall. We test the conjecture in the context of the AdS/CFT correspondence. There are topological constraints on existence of an interface […]

Thermal Instability in the CGM of $L_{star}$ Galaxies: Testing “Precipitation” Models with the FIRE Simulations

Kavli Affiliate: Andrey V. Kravtsov | First 5 Authors: Clarke J. Esmerian, Andrey V. Kravtsov, Zachary Hafen, Claude-Andre Faucher-Giguere, Eliot Quataert | Summary: We examine the thermodynamic state and cooling of the low-$z$ Circum-Galactic Medium (CGM) in five FIRE-2 galaxy formation simulations of Milky Way-mass galaxies. We find that the CGM in these simulations is […]

Ultrafast coherent control of a hole spin qubit in a germanium quantum dot

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Gang Xu, Fei Gao, He Liu, Rong-Long Ma | Summary: Operation speed and coherence time are two core measures for the viability of a qubit. Strong spin-orbit interaction (SOI) and relatively weak hyperfine interaction make holes in germanium (Ge) intriguing candidates for spin qubits with […]
