🎉 ULASAN NOBEL FISIKA 2026!
“Francis Halzen, IceCube, dan ‘Partikel Hantu’ dari Antariksa”

👋 Halo Sobat-Q! Nobel Fisika 2026 di pekan ini baru saja dianugerahkan kepada Francis Halzen “for decisive contributions to the IceCube Neutrino Observatory and the discovery of high-energy neutrinos of astrophysical origin”.

👻 Neutrino sering dijuluki “partikel hantu”. Partikel elementer ini tidak bermuatan, massanya sangat kecil, bergerak mendekati kecepatan cahaya, dan hampir tidak berinteraksi dengan materi. Triliunan neutrino dari matahari bahkan menembus tubuh kita setiap detik tanpa terasa.

⚡ Sejak diprediksi Pauli dari tahun 1930 hingga ditemukan beberapa kali oleh ilmuwan-ilmuan setelahnya, ternyata ada banyak sekali macam neutrino! IceCube yang dipimpin Halzen memburu neutrino yang berenergi sangat tinggi. Energinya dapat jauh melampaui energi partikel yang dipercepat di Large Hadron Collider (CERN). Dari mana datangnya? Dari proses-proses ekstrem di alam semesta, misalnya di sekitar objek kosmik yang sangat energik.

🧊 Masalahnya, neutrino sangat sulit dideteksi. Solusinya adalah memanfaatkan es Antartika yang tebal, jernih, dan gelap. IceCube menanam ribuan sensor cahaya jauh di bawah permukaan es. Ketika neutrino berinteraksi dengan materi, partikel bermuatan yang terbentuk dapat menghasilkan kilatan cahaya yang kemudian direkam oleh sensor.

🔭 Dari pola cahaya itu, ilmuwan dapat memperkirakan energi dan arah datang neutrino. Inilah yang membuat neutrino menjadi “pembawa pesan” dari tempat-tempat kosmik yang sangat jauh dan sulit dipelajari hanya dengan teleskop biasa.

🌌 Mengapa penting? Neutrino dapat membawa informasi langsung tentang proses fisika di lingkungan ekstrem, membantu kita melacak “alamat asal” akselerator kosmik, dan membuka cara baru mempelajari alam semesta melalui astronomi multimessenger.

🏅 Nobel 2026 ini juga menunjukkan pencapaian besar yang lahir dari kerja kolaboratif. IceCube menggandeng fisika teori, instrumentasi, komputasi, analisis data, dan logistik ekstrem di Kutub Selatan. Dalam konteks Indonesia, semangat ini semestinya harus dipupuk dengan nilai gotong royong dalam sains.

📚 ABSTRACT:
We are in the era of precision cosmology, driven by the advent of ongoing and future galaxy surveys. Galaxy clustering, utilizing the three-dimensional distribution of galaxies, is one of the most powerful probes for cosmology. To extract new physics from this data, however, we must focus on three key areas: higher-order statistics, nonlinear modeling, and systematics.

First, I will highlight the importance of higher-order statistics by presenting a joint analysis of the power spectrum and bispectrum using Euclid Flagship I simulations. The bispectrum captures additional information that standard two-point measurements miss, which improves our constraints on key cosmological parameters like the scalar amplitude, matter density, and primordial non-Gaussianity.

Next, I will tackle nonlinear modeling by detailing a model-independent, symmetry-guided approach to Lagrangian perturbation theory. Finally, I will address survey systematics in the galaxy bispectrum, presenting an exact method for window function convolutions and demonstrating how wide-angle effects can sometimes create false signals that mimic local primordial non-Gaussianity.

📚 ABSTRACT:
In 80’s, there were two remarkable discoveries in physics, i.e., quantum Hall effect and high temperature superconductors. The former introduced the concept of geometry and topology, while the latter the strong correlation in electronic systems. These two streams now merge into a large and single stream of research in condensed matter physics. In this talk, I will discuss the interplay between these two aspects of condensed matter physics including gauge theory of high Tc cuprates [1], anomalous Hall effect in magnets [2] and spin Hall effect in semiconductors [3], multiferroics in Mott insulators [4], topological spin textures in chiral magnets [5], nonlinear transport, and nonlinear optical responses in noncentrosymmetric materials [6].

🎉 CERITAKU (Cerita Kuantum) 2026 | EDISI #06
"Baterai Kuantum ala Min-Q: Makin Lambat, Makin Cepat?"

👋 Halo Sobat-Q, apa jadinya kalau para Min-Q dan desainer/admin quantumresearch.id melakukan riset kuantum bersama? Paper ini salah satu hasil kolaborasinya!

🔋 Pernah dengar baterai kuantum? Berbeda dari baterai biasa yang menyimpan energi lewat proses kimia, baterai kuantum memanfaatkan sistem kuantum untuk menyimpan dan memindahkan energi. Salah satu target risetnya adalah membuat pengisian lebih cepat dan efisien.

💡 Kandidat baterai kuantum yang kerap muncul di literatur adalah baterai berbasis osilator kuantum, yang secara ideal dapat menampung banyak tingkat eksitasi. Masalahnya, saat charger dan baterai terus terhubung, energi dapat bolak-balik di antara keduanya sehingga energi yang tersimpan menjadi terbatas.

⚡ Penelitian terbaru para Min-Q bersama seorang profesor dari Fisika ITB menawarkan solusi sederhana. Interaksi charger dan baterai tidak langsung dibuat kuat, tetapi dinaikkan perlahan melalui proses "slow quench".

⚛️ Hasilnya cukup mengejutkan. Semakin lambat quench dilakukan, semakin besar energi maksimum dan daya pengisian yang dapat dicapai. Dalam kondisi tertentu, proses yang lebih lambat justru menghasilkan charging yang lebih kuat.

🌊 Mengapa? Slow quench membantu menekan osilasi energi antara charger dan baterai. Energi dari sumber penggerak dapat terus terkumpul lalu dipindahkan ke baterai dengan lebih efektif. Min-Q menyebut perilaku ini "temporal extensivity", karena peningkatan performanya berasal dari lamanya proses pengisian.

🔬 Dalam sistem riil, kehilangan energi dan decoherence tetap membatasi efek ini sehingga ada durasi quench yang optimal. Studi ini masih teoretis, tetapi prediksinya diharapkan dapat diuji pada rangkaian superkonduktor dan "microcavity" kuantum.

📚 ABSTRACT:
Glueballs, particles composed solely of gluons, are considered to play a key role in understanding one of the most challenging problems in modern physics: color confinement and the origin of mass in QCD. In the dual superconductor picture, glueballs can be viewed as closed flux tubes. It has been conjectured that such states are described by topological solitons with knotted structures, known as Hopfions, in a low-energy effective model of QCD. In this talk, we develop a model of glueballs in terms of Hopfions. We perform semiclassical quantization of Hopfions and assign quantum numbers, such as spin, to these configurations. As a result, we obtain a quantized mass formula for Hopfions. We find that the Hopfion energy spectra are compatible with the prediction of glueball mass by lattice QCD, and that there exist some glueball candidates observed in experiments of which mass agrees very accurately with Hopfion energy.

📚 ABSTRACT:
Nuclear magnetic resonance (NMR) spectroscopy and imaging (MRI) of nuclei other than a proton, especially of mass-limited samples, is hampered by the low signal sensitivity due to the tiny differences in spin populations between the nuclear Zeeman energy levels. This intrinsic NMR insensitivity of nuclei such as carbon-13 or nitrogen-15 stems from their relatively low gyromagnetic ratio, leading to lower Boltzmann-dictated thermal nuclear polarization, thus lower NMR or MRI signal.

Dynamic nuclear polarization (DNP) or hyperpolarization via the dissolution method, an offshoot of a technology used in particle physics and nuclear scattering experiments, has solved this insensitivity problem by amplifying the magnetic resonance signals of insensitive nuclei such as carbon-13 by >10,000-fold. The trick is to transfer the high electron thermal polarization to the nuclear spins via microwave irradiation close to the electron spin resonance (ESR) frequency of the free radicals at low temperature (close to 1 K) and high magnetic field (>1 T).

In this talk, I will delve into the discussion of the physics, instrumentation and engineering aspects, optimization methods, and biomedical applications of the dissolution DNP technology. This cutting-edge physics technology is currently improving cancer diagnostics by providing biochemical and metabolic information at the molecular level with superb sensitivity and high specificity.

💦 ABSTRACT:
In the absence of a complete theory of quantum gravity, effective models provide useful laboratories for testing candidate descriptions. In symmetry-reduced loop quantum gravity (LQG), non-perturbative holonomy corrections raise the question of whether the resulting dynamics admits a consistent spacetime interpretation. Effective modified gravity (EMG) addresses this by extending pointwise holonomy modifications beyond standard polymerization while preserving covariance, leading to a robust non-singular black-to-white-hole transition. For scale-dependent holonomy corrections that decay asymptotically, the Hawking temperature and the universal low-energy absorption cross section remain unchanged at leading order, while quantum-geometry effects enter through subleading greybody-factor corrections. Nevertheless, they do impact energy emission of the black hole and its final state in a crucial way regarding one of the main questions of black-hole evaporation: whether a black-to-white-hole transition, or a stable remnant, is preferred. For the first time, a first-principles derivation based on backreaction reveals a mechanism capable of producing either end state.
